 # Xinje PLC Programming

 Version: 1.5.0

 Use this skill to help with Xinje PLC and HMI tasks. Treat the skill as a practical engineering assistant: clarify the controller and software context first, use the bundled references when the task matches them, and keep safety, maintainability, and commissioning steps visible.

 ## First Response Workflow

 1. Identify the task type: PLC logic, XDPPro operation, communication, TouchWin HMI, commissioning/debugging, documentation, or template generation.
 2. Ask only for missing information that materially changes the answer: PLC model/series, XDPPro version, firmware version, HMI model, connection method, I/O list, device protocol, and current machine state.
 3. For known confusing topics or disputed claims, read `references/accuracy-rules.md` before answering and label evidence as manual, software observation, engineering inference, or unknown.
 4. State assumptions when proceeding without complete information.
 5. Use the reference map below to load only the file needed for the task.
 6. For any operation that can affect live equipment, read `references/safety-debug-checklist.md` and include a short safety check before the steps.
 7. End with a verification or commissioning checklist when the user is implementing code or changing PLC/HMI configuration.

 ## Reference Map

 - `references/xdp-pro-ch2-5-reference.md`: Read for XDPPro basic operation, project creation, multi-PLC projects, USB/serial/Ethernet connection, upload/download, online download, ladder editing, ST execution blocks, PLC configuration, Modbus TCP graphic setup, motion/process-control entry points, monitoring, oscilloscope, and information/status bars.
 - `references/xdh-60t4-servo-motion.md`: Read first for XDH-60T4 servo work. It distinguishes the four local OC pulse-plus-direction axes from EtherCAT bus axes, covers configuration, DRVI/DRVA/ZRN, A_PWR/A_MOVER/A_MOVEA/A_HOME, commissioning, diagnostics, and exact official PDF source pages.
 - `references/ds5c-20p4-pta-drive.md`: Read for the DS5C-20P4-PTA drive used with XDH-60T4. It covers the confirmed 0.4kW single-phase model, motor/encoder/EtherCAT interfaces, cable-code checks, CSP/HM setup, XDH commissioning route, braking-resistor constraints, alarms, and safety boundaries.
 - `references/accuracy-rules.md`: Read first for P0 accuracy guardrails, evidence levels, forbidden claims, `M8000`/`SM000`, risky `SM`/`SFD` writes, online/secure download claims, and HMI/PLC control-bit conflicts.
 - `references/p0-regression-prompts.md`: Read when validating this skill after changes or checking whether it still avoids known bad answers.
 - `references/ladder-basic-instructions.md`: Read for P2 ladder basics: `LD/LDI/OUT`, `AND/OR`, edge contacts, `PLS/PLF`, `SET/RST`, `ALT`, timers, counters, compare/move/arithmetic, double-coil risks, and common ladder patterns.
 - `references/soft-elements-and-special-relays.md`: Read for soft-element tables, `SM0`/`SM000` naming, the correction that `M8000` is not a Xinje XD/XL/XG special relay, `SM000~SM003`, first-scan initialization, special auxiliary relays, `SD`/`SFD` registers, address rules, and XD/XL/XG model-specific soft-element questions.
 - `references/touchwin-screen-animation.md`: Read for P1 TouchWin screen switching, PLC-register-driven screen changes, current-screen reporting, buttons, indicator buttons, translation animation, rotation animation, moving cart animation, visibility/enable controls, and simulation/download checks.
 - `references/touchwin-alarms-recipes.md`: Read for P1 TouchWin alarms, alarm display/list, real-time and historical events, CSV import/export, recipes, recipe download/upload, internal PSB/PSW/PFW notes, and HMI data storage cautions.
 - `references/plc-hmi-integration-patterns.md`: Read for P3 PLC-HMI integration templates: command/status/ack handshakes, address allocation, HMI buttons writing PLC bits, PLC-controlled screen switching, alarms, parameter writes, and commissioning tables.
 - `references/communication-modbus-and-troubleshooting.md`: Read for P4 communication tasks: PC-to-PLC, HMI-to-PLC, Modbus RTU/ASCII/TCP, XDPPro graphic Modbus TCP, serial parameters, station/IP/port checks, status relays/registers, and troubleshooting workflow.
 - `references/p0-p1-official-manuals-overview.md`: Read when a question needs official P0/P1 PDF source routing for PLC hardware, expansion modules, Ethernet communication, TS/TouchWin Pro, TS/TG hardware, HMI communication, or FAQ/manual fallback.
 - `references/xinje-official-document-catalog.md`: Read before searching/downloading official Xinje manuals, drawings, EPLAN files, samples, or certificates. Use the full CSV/JSON catalog under `assets/catalogs/` for exact file IDs, URLs, versions, update dates, and categories.
 - `references/coverage-map.md`: Read when you need to know whether a manual is only cataloged, downloaded, overviewed, focused, detailed, or complete. Use it to avoid overstating what the skill has distilled.
 - `references/maintenance-workflow.md`: Read when updating this skill, adding a manual, refreshing the official document catalog, or converting repeated failures into reusable workflow knowledge.
 - `references/future-expansion-plan.md`: Read when deciding what to download or distill next after v1.0.0. It records P2/P3/P4 priorities and catalog-only defaults.
 - `references/known-ingestion-issues.md`: Read before using the Xinje download center, Chinese PDF extraction, PowerShell UTF-8 output, official CDN URLs, or file-ID downloads.
 - `references/touchwin-overview.md`: Read for TouchWin v0.1 coverage: project creation, screen editing, simulation, upload/download, HMI communication, alarms, recipes, macros, variables, and registers. This is an overview until detailed TouchWin references are added.
 - `references/safety-debug-checklist.md`: Read before answering live download, online modification, forced I/O, register writes, initialization, motion, heating/PID, or commissioning questions.
 - `references/plc-output-templates.md`: Read when producing I/O tables, soft-element tables, ladder-network plans, HMI variable lists, alarm tables, or debug records.
 - `references/source-index.md`: Read when you need source provenance, page ranges, and which original PDFs were used.
 - `references/manual-search-index.md`: Read before broad manual lookup. Search `assets/indexes/xinje-manual-fulltext.sqlite` with `scripts/search_xinje_manuals.py` first; use `references/manual-chapter-index.md` for generated directory/page routing; open original PDFs only for layout-sensitive or high-risk verification.
 - `scripts/`: Use for repeatable maintenance tasks: catalog official Xinje download-center metadata, download an official file by URL or file ID, build/search the page-level manual index, search PDF keywords, and extract PDF page ranges.
 - `scripts/release_skill.ps1`: Run after a completed skill change to increment the release version by `0.1`, commit the complete change set, and push it to the configured Git remote. Read `references/maintenance-workflow.md` first.
 - `assets/manuals/`: Use only as original-manual fallback when Markdown references are insufficient, especially for screenshots, tables, icons, page layout, or exact UI wording.
 - `assets/catalogs/`: Use for generated official download-center metadata. Do not load the full JSON/CSV unless the task requires catalog search.

 ## PLC Logic Guidance

 When asked to design or review PLC logic:

 1. Request or infer the I/O list, process sequence, manual/auto requirements, interlocks, alarms, reset behavior, and safe stop behavior.
 2. Produce an I/O table and soft-element allocation before writing logic when the task is more than a trivial rung.
 3. Prefer ladder logic descriptions for field-maintenance readability. Use ST execution blocks for calculations, structured assignments, or compact data handling when appropriate.
 4. Separate outputs, commands, permissives, interlocks, alarms, timers/counters, and HMI-facing registers.
 5. Include commissioning checks: offline review, simulation or monitor points, manual mode tests, auto dry-run, alarm tests, and recovery tests.

 For `M8000`-style questions, do not treat `M8000` as a Xinje XD/XL/XG special relay or as equivalent to `SM000`. Use `SM000`/`SM0` for PLC running always-ON. If a Xinje project/software accepts `M8000`, treat it as an ordinary `M` auxiliary relay address unless a specific manual explicitly says otherwise. Do not invent exact device support, unsupported special registers, or instruction behavior when the bundled references do not cover them. Ask for the specific manual or say that a Xinje instruction/communication/manual reference is needed.

 For ladder generation, use `ladder-basic-instructions.md` and produce a soft-element allocation plus rung/network plan. Prefer safe command/status separation for anything driven by HMI.

 When adding new manuals, follow `maintenance-workflow.md`: catalog first, download only when needed, create a full-manual overview and coverage-map entry before bundling, and mark unfinished coverage honestly.

 ## XDPPro Operation Guidance

 For XDPPro usage questions, use `xdp-pro-ch2-5-reference.md` and answer as a procedure. Include the relevant path in the software, such as `选项 -> 软件串口设置`, `PLC操作 -> 下载用户程序`, or `PLC配置 -> I/O`.

 Always distinguish:

 - USB, serial, and Ethernet connection setup.
 - Normal download, encrypted download, and online download.
 - Uploading user program versus uploading user program and configuration.
 - Monitoring ladder/ST logic versus data monitoring and free monitoring.

 Warn that encrypted download can prevent later upload, and that online download can change running-machine behavior.

 ## Communication Guidance

 For communication tasks:

 1. Clarify whether the task is PC-to-PLC connection, PLC serial communication, Modbus RTU/ASCII, Modbus TCP, Ethernet/IP, CANopen, EtherCAT, XNET, or HMI-to-PLC communication.
 2. Clarify master/slave role, station number, IP, port, baud rate, parity, register map, function codes, and data type/endianness when relevant.
 3. Use `communication-modbus-and-troubleshooting.md` for Modbus and communication troubleshooting; for Modbus TCP graphic setup, use `PLC 通讯 -> Modbus TCP` guidance from the XDPPro reference.
 4. For Ethernet, Modbus TCP, socket/free-format communication, or EtherNet/IP details, use the bundled official Ethernet manual identified in `p0-p1-official-manuals-overview.md`.
 5. For XDH-60T4 pulse positioning or EtherCAT servo work, use `xdh-60t4-servo-motion.md`; also read `ds5c-20p4-pta-drive.md` when the project uses DS5C-20P4-PTA. For other CANopen, EtherCAT, advanced-motion, or full drive-model details, route to `future-expansion-plan.md` and the corresponding Xinje special manual unless that reference has been added.

 ## TouchWin HMI Guidance

 For TouchWin tasks:

 1. Clarify HMI model, PLC model, connection method, protocol, screen count, variables, alarm needs, recipe needs, and whether the task is editing, simulation, download, upload, or troubleshooting.
 2. Use `touchwin-screen-animation.md` for screen switching, PLC-controlled page changes, and animation; use `touchwin-alarms-recipes.md` for alarms, event lists, recipes, and HMI internal objects.
 3. For TS/TouchWin Pro model, component, communication, hardware, pass-through, or FAQ details, use `p0-p1-official-manuals-overview.md` to route to the correct bundled official PDF.
 4. Use HMI variables/registers consistently with the PLC soft-element allocation.
 5. For screens, describe controls by purpose: status display, command buttons, numeric entry, alarm list, recipe management, maintenance/debug page.
 6. Include a test path: offline simulation, online simulation when available, download, PLC communication test, alarm/reset test, recipe read/write test.

 ## Safety Boundaries

 - Do not help bypass unknown passwords, crack project protection, or recover protected/encrypted programs.
 - Do not present live download, forced output, register writes, initialization, or motion commands as routine steps. Always include a safety precheck.
 - For safety circuits, emergency stops, guards, light curtains, STO, and hardwired interlocks, distinguish PLC logic from required hardware safety design and tell the user to follow applicable machine-safety standards.

 ## Output Style

 Prefer compact, implementable engineering output:

 - Known assumptions.
 - Required user inputs.
 - I/O and soft-element tables.
 - Step-by-step XDPPro/TouchWin operations.
 - Ladder-network or ST block plan.
 - Safety and commissioning checklist.
 - Source note when relying on bundled references.

 # Accuracy Rules

 Use this P0 reference before answering known confusing Xinje PLC/HMI questions, before changing the skill, and before making claims that depend on exact manual wording.

 ## Evidence Levels

 | Level | Meaning | How to answer |
 |---|---|---|
 | A - manual | The bundled official manual or official Xinje document explicitly says it. | Answer directly and cite the manual/page or section. |
 | B - software observation | XDPPro/TouchWin behavior was observed, but the manual wording is absent or incomplete. | Say "software appears/allows..." and do not turn it into an official definition. |
 | C - engineering inference | A practical conclusion follows from PLC/HMI behavior or common practice. | Mark it as an inference and ask for model/version if it affects safety or compatibility. |
 | D - unknown | The skill has not verified the claim. | Do not guess. Search the catalog/manual or ask for the exact model/manual. |

 ## Hard Rules And Forbidden Claims

 | Topic | Correct rule | Do not say | Evidence/source anchor |
 |---|---|---|---|
 | `M8000` on XD/XL/XG | `M8000` is not documented as a Xinje XD/XL/XG special relay. If accepted by software and in range, treat it as ordinary `M` memory. | "`M8000 = SM000`" or "`M8000` is the run always-ON relay." | XD/XL and XG basic manuals list `SM000` for run always-ON; no explicit `M8000 = SM000` definition found. |
 | Run always-ON | Use `SM000` / `SM0`. | Use `M8000` for XD/XL/XG run always-ON. | `soft-elements-and-special-relays.md`; XD/XL basic manual appendix special relays. |
 | First scan | Use `SM002` / `SM2` for first-scan ON pulse. | Use `M8002` as an XD/XL/XG official first-scan relay unless the project/manual explicitly uses it. | `soft-elements-and-special-relays.md`. |
 | `SM0` vs `SM000` | Treat `SM0` as short input form for `SM000` when software/manual context confirms zero-padded addressing. | Generalize this rule to every device family without checking. | XDPPro software and XD/XL/XG manuals use `SM000` naming; software/manual examples also use `SM0`. |
 | `M` vs `HM` | `M` is ordinary auxiliary relay; `HM` is retentive auxiliary relay. | Claim every `M` persists after power loss. | Basic instruction manual soft-element chapter. |
 | `SM` writes | Many `SM` bits are system/special bits. Read their function before writing. | Treat `SM` as free user memory. | `soft-elements-and-special-relays.md`; safety checklist. |
 | `FD`/`SFD` writes | Flash-backed registers have write-life and behavior cautions; use edge-triggered writes and avoid periodic writes. | Drive `FD`/`SFD` writes with clock pulses such as `SM011`. | XD/XL basic manual soft-element notes mention Flash write life and edge-effective `MOV`. |
 | Online download | Online download can change running-machine behavior. Require backup and safety check. | Present online download as routine and harmless. | XDPPro software manual PDF pages 53-54. |
 | Secure/encrypted download | Secure download can make later upload impossible. Warn before recommending. | Tell users it is just a normal download option. | XDPPro software manual PDF page 53 and toolbar description page 24/31. |
 | HMI button writes PLC bit | If TouchWin operates a PLC bit, avoid driving the same bit with PLC `OUT` in normal scan. Use command/status separation. | Use the same `M` as both HMI direct control bit and PLC output coil. | TouchWin manual PDF page 75. |
 | TouchWin PLC-controlled screen switch | The interaction register value selects a screen number and is cleared to 0 after jump. Drive it with an edge/event. | Continuously write the target page number every scan. | TouchWin manual PDF page 38. |
 | `ALT` | `ALT` toggles a bit and is edge-triggered; if driven by a level that is true every scan, it can repeatedly toggle. | Use `ALT` under always-ON condition for stable state. | XD/XL basic manual PDF page 88 and FAQ mention ALT output flashing. |

 ## Answering Pattern For Disputed Topics

 Use this shape:

 1. State the conclusion.
 2. Separate manual wording from software observation.
 3. Name the safe substitute.
 4. Give a short verification path.

 Example:

 ```text
 For XD/XL/XG, do not use M8000 as a system always-ON bit. The manual documents SM000/SM0 as PLC running always-ON. If XDPPro accepts M8000, treat it as ordinary M memory within the valid address range. Verify by monitoring SM0 and M8000 separately while the PLC is in RUN.
 ```

 ## When To Escalate To Manual Lookup

 Look up the original PDF or official catalog when:

 - the answer depends on exact address ranges for a CPU model,
 - the topic involves firmware/version support,
 - a device may move, heat, clamp, pump, or write retentive/Flash data,
 - the user reports software behavior that conflicts with current references,
 - the user asks for a page number/source.

 # Communication, Modbus, And Troubleshooting

 Use this P4 reference for Xinje PLC/HMI communication questions, Modbus RTU/ASCII/TCP setup, XDPPro connection, HMI-to-PLC communication, status diagnosis, and troubleshooting.

 Source anchors:

 - XDPPro software manual PDF pages 21-22: TouchWin-style project creation requires HMI model, PLC port, download port, and communication parameters.
 - XDPPro software manual PDF pages 33-46: PLC connection through serial/Ethernet and IP/network notes.
 - XDPPro software manual PDF pages 110-112: `PLC 通讯 -> Modbus TCP` graphic configuration, model/firmware support, slave nodes, instruction rows, trigger modes.
 - XD/XL basic instruction manual chapter 6 and PDF pages around 250+: Modbus RTU/ASCII, Modbus address, communication instructions.
 - `soft-elements-and-special-relays.md`: serial communication status relays such as `SM140~SM193` and communication result registers such as `SD140~SD199`.

 ## First Questions

 Clarify:

 | Item | Examples |
 |---|---|
 | Link type | PC-to-PLC, HMI-to-PLC, PLC-to-device, PLC-to-PLC. |
 | Physical layer | USB, RS232, RS485, Ethernet. |
 | Protocol | Xinje protocol, Modbus RTU, Modbus ASCII, Modbus TCP, XNET, Ethernet/IP, CANopen, EtherCAT. |
 | Role | Master/client or slave/server. |
 | Parameters | Station ID, IP, port, baud rate, data bits, stop bits, parity, timeout, retry count. |
 | Data map | Coil/register address, function code, word width, signed/unsigned, float, byte/word order. |
 | Version | PLC model, firmware, XDPPro version, HMI model/TouchWin version. |

 ## PC To PLC In XDPPro

 Common paths:

 - USB/serial/Ethernet connection setup in XDPPro.
 - `选项 -> 通讯方式设置` for communication mode.
 - `选项 -> TCP/IP 设备设置` for Ethernet devices.
 - `选项 -> 软件串口设置` for serial settings.
 - Status bar shows model, communication mode, and PLC running status.

 Troubleshooting:

 1. Confirm correct cable/driver/interface.
 2. Confirm only one application is using the serial port.
 3. For Ethernet, confirm PC and PLC are in the same subnet and only the intended NIC is active.
 4. Confirm PLC ID/IP/station.
 5. Try upload/monitor after basic connection succeeds.

 ## HMI To PLC In TouchWin

 In TouchWin project creation:

 1. Select the correct HMI model.
 2. Set `PLC 口` to the correct PLC/device type and communication parameters.
 3. Set `下载口` to unused or to the correct communication device if it will communicate with lower devices.
 4. Use the correct station number in each HMI component.
 5. For online simulation, confirm PC-to-device hardware supports it; USB download alone may not support lower-device monitoring.

 Common symptoms:

 | Symptom | Checks |
 |---|---|
 | HMI shows "正在通讯" | Protocol, station, serial port, cable, COM occupancy, PLC port setting. |
 | Values display wrong | Address notation, word width, signed/unsigned, float, scaling, byte order. |
 | HMI button does not work | Button object address, station, PLC double-coil conflict, HMI permission/enable control. |
 | Download port cannot communicate | Confirm download port is configured for communication mode, not only program download. |

 ## Modbus RTU/ASCII

 Required parameters:

 | Parameter | Notes |
 |---|---|
 | Station | Must match slave ID. |
 | Baud rate | Match all devices on the bus. |
 | Data bits / stop bits / parity | Must match exactly. |
 | Wiring | RS485 A/B polarity, shield/grounding, termination for long/high-speed networks. |
 | Function code | Coil/register read/write must match target map. |
 | Register map | Confirm 0-based vs 1-based addressing and device-specific offsets. |

 PLC-side concepts:

 - Communication instructions include coil read/write and register read/write groups.
 - XD/XL Modbus RTU handling queues multiple communication requests differently than old XC-style examples; still avoid uncontrolled repeated triggers.
 - Use edge/condition triggers for write commands to avoid flooding a device.

 Diagnosis:

 1. Use a serial tool first when integrating a third-party device.
 2. Verify a single read of one known register.
 3. Add writes only after reads are stable.
 4. Monitor communication busy/done/error bits and result registers.
 5. Increase timeout/retry only after parameter and wiring checks.

 ## Modbus TCP Graphic Configuration In XDPPro

 XDPPro path:

 ```text
 工程 -> PLC 通讯 -> Modbus TCP
 ```

 The software manual describes model/firmware support and a graphic table with:

 - master connection information,
 - slave node add/delete/copy/properties,
 - instruction add/insert/delete/move/import/export,
 - trigger mode: cyclic ms or conditional trigger,
 - slave station number,
 - function code,
 - mapping/cache address,
 - timeout/retry,
 - connection flag/result storage.

 Use this when the PLC model/firmware supports graphical Modbus TCP. Otherwise route to the Ethernet communication manual or use instruction/socket method as appropriate.

 ## Status Relays And Result Registers

 From the current soft-element reference:

 | Range | Use |
 |---|---|
 | `SM140~SM193` | Serial-port communication status flags. |
 | `SD140~SD199` | Communication result registers. |

 Example pattern:

 - Serial port 0: `SM140` Modbus executing, `SM141` X-NET executing, `SM142` free-format sending, `SM143` free-format receive complete.
 - `SD140` is the Modbus read/write result for serial port 0 in the referenced XD/XL manual.

 Always verify the exact port group and model table before writing production diagnostics.

 ## Troubleshooting Checklist

 1. Identify master/slave and protocol.
 2. Confirm physical wiring and interface.
 3. Confirm station/IP/port and serial parameters.
 4. Confirm register/coil address map and function code.
 5. Confirm data type and byte/word order.
 6. Test one read, then one write.
 7. Monitor status bits/result registers.
 8. Check timeout/retry and polling interval.
 9. Check HMI/PLC project settings use the same station and protocol.
 10. Record final parameters in the project documentation.

 ## Safety Notes

 - Communication writes can move outputs indirectly; treat write commands as live machine actions.
 - Do not test write-multiple-registers against motion, heating, pressure, or recipe ranges without a safe machine state.
 - Keep manual controls and emergency stops independent of the communication link.

 # DS5C-20P4-PTA 驱动器

 本参考面向 `XDH-60T4 + DS5C-20P4-PTA`。默认推荐 EtherCAT 总线轴方案：`XDH LAN2 -> DS5C IN -> DS5C OUT`。驱动器的 CN0 脉冲输入也存在，但同一机械轴不得同时接受 EtherCAT 运动指令和 PLC 本体脉冲指令。

 任何接线、参数写入、使能、回零或试转前，必须确认设备停机、急停/防护门/外部限位有效、机械区域清空，并保存当前 PLC 与驱动器参数。本文不把 PLC/驱动器的一般 I/O 当作 STO 或安全回路。

 ## 已确认的型号与接口

 | 项目 | DS5C-20P4-PTA 官方规格 | 工程结论 |
 |---|---|---|
 | 驱动器 | 0.4kW，单相 AC200-240V，50/60Hz，风冷 | 主电源只接 `L/N`，不得接入 `U/V/W`。 |
 | 输出能力 | 连续输出电流 2.8A，最大输出电流 9.8A | 电机必须与驱动器功率/电机代码匹配，不能仅因插头能插上而使用。 |
 | 主回路 | `L/N` 输入；`U/V/W` 接电机；PE 接地 | 电机动力线接在驱动器侧，不接 PLC。接地端在散热片处。 |
 | 编码器 | `CN2` | 编码器线只连接驱动器和电机，不接 PLC。 |
 | EtherCAT | 两个标准 RJ45 口，`IN/OUT` 线型拓扑 | 用屏蔽双绞线；驱动器为从站，XDH 为主站。 |
 | CN0 | PUL/DIR 与三入三出 I/O（本机型小于 1kW） | 仅用于脉冲控制或独立 I/O；EtherCAT 方案不把它当作主运动命令通道。 |

 来源：DS5C 手册 PDF 13、46、49-51、80。

 ## 当前线缆核对

 | 用户提供线缆 | 官方命名解释 | 结论 |
 |---|---|---|
 | `CP-SP-M-03` | `CP` 普通型编码器线；`SP` 为安普插头、S01 电机；`M` 不带电池盒；`03` 为 3m。 | 命名与 DS5C 手册完全对应。它要求电机端确为 S01 型接口；不要把它用于 S02/B 系列接口。 |
 | `CM-P07-03` | 手册的完整命名示例为 `CM-P07A-M-03`：`CM` 普通型动力线、`P` 小功率 4 芯安普插头、`07` 代表 0.75mm2、`03` 为 3m；`A/B` 和 `M` 还定义驱动器侧端子与线缆类型。 | 现有型号缺少 `A-M` 后缀，不能只凭简写确认驱动器端压接端子和线缆类型。以实物完整标签/采购清单为准。 |

 无论线缆型号如何，电机型号仍需从铭牌确认。驱动器上 `U3-70` 的电机代码应与电机铭牌的 MOTOR CODE 一致；不确定时不要通过修改 `P0-33` 强行消除电机代码报警。

 来源：DS5C 手册 PDF 11、18、21-24、258-259。

 ## 接线边界

 ### 驱动器、电机与 PLC

 1. 单相 AC200-240V 接入驱动器 `L/N`；绝不把电源接入 `U/V/W`。
 2. 电机动力线接驱动器 `U/V/W/PE`，编码器线接 `CN2`。动力线、编码器线和控制/通讯线分开布设，控制信号线与动力线间距至少 30cm。
 3. EtherCAT 使用 `XDH LAN2` 接第一台 DS5C `IN`，再由该驱动器 `OUT` 接下一台 DS5C `IN`。这不是“网线转 RS-232”链路；RS-232 转接线不能替代 EtherCAT 线。
 4. `DS5C-20P4-PTA` 的 CN0：PUL-/P+24V 是集电极开路脉冲输入，DIR-/D+24V 是方向输入，`SI1~SI3` 为输入，`SO1~SO3` 为输出。若项目最终采用 XDH 本地脉冲，请单独设计 CN0 接线与极性；若采用 EtherCAT，不要同时给该轴触发 `DRVI/DRVA/ZRN`。

 来源：DS5C 手册 PDF 5、46、49-51、262；XDH 高级运动控制篇 PDF 8-10。

 ## EtherCAT 调通顺序

 1. 在无使能、无负载风险状态接通总线，检查 DS5C `IN/OUT` 链路灯和物理顺序。
 2. 在 XDPPro 的 EtherCAT 界面扫描或添加设备；从站列表顺序必须与实际接线一致，`StationID 0` 为第一台。
 3. 常规配置下将从站功能选择为 Servo Module。CSP 基础配置使用 PDO 映射 `1600`、`1A00`，启动参数 `6060h=8`；默认 IO 映射起始地址可为 `HD10000`，但以当前工程实际映射为准。
 4. 执行“配置写入 -> 激活 -> 确定”。激活会使从站经 `Init -> PreOP -> SafeOP -> OP`；监控 `SD8021`，值 `8` 才是 OP，此时 SDO/PDO 才能收发。
 5. 确认轴配置的指令通道是 EtherCAT：`SFD8001+300*N = 0`。随后只用对应逻辑轴的高级运动指令或 POU，例如 `A_PWR`、`A_MOVER`、`A_MOVEA`、`A_HOME`/`BMC_A_POWER`。

 DS5C 支持 100BASE-TX、屏蔽双绞线、线型拓扑，节点间最长 50m。DS5C 3791 及后续版本支持 1000/2000/4000/8000/10000us 通讯周期；XDH 的实际周期仍应按轴数、驱动器固件与现场负载选择，先以保守值调通。

 来源：DS5C 手册 PDF 75-91、262-266；XDH 高级运动控制篇 PDF 10-18。

 ## HM 驱动器回零

 总线轴可使用 DS5C 内部 HM 回零，也可用 XDH 高级运动轴配置的 HOME/A_HOME。二者须选择一种作为该轴的唯一回零责任方，避免 PLC `ZRN`、驱动器 HM 和高级运动 `A_HOME` 同时管理同一轴的原点。

 DS5C HM 模式的官方流程：

 1. 将 `6060h` 设为 `6`，且在电机未使能状态下切换模式。
 2. 将 `6098h`（回零方式）与 `609Ah`（回零加速度）加入 RxPDO；`6099h`（高速/低速）经 SDO/CoE-Online 设置。
 3. 默认限位/原点端子分配为：`P5-22=1 -> SI1` 正限位，`P5-23=2 -> SI2` 负限位，`P5-27=3 -> SI3` 原点。不要假定现场参数仍是默认值，先在线读取。
 4. OP 且使能完成后，`6040h` 控制字从 `15` 变为 `31` 触发一次回零；再次回零前先回到 `15`，再切到 `31`。

 以 `6098h` 为 1/2/3/4 等方式时，原点、正负限位和电机 Z 相的组合不同。先确认现场传感器到底接在驱动器 SI 还是 PLC X 输入，再选方式；错误选型会使轴向错误方向找限位。

 来源：DS5C 手册 PDF 106-118、273-275。

 ## 制动电阻、报警与安全边界

 - 对 `DS5C-20P4-PTA`，外置制动电阻最小阻值 40ohm，推荐 40-100ohm、500W 以上。使用外置电阻时接 `P+ / C`、拆除 `P+ / D` 短接线，并设置 `P0-25`、`P0-26`。只有在垂直轴、高惯量或频繁减速等再生工况经计算确认需要时才实施；这是高压高温操作。
 - 典型排查：`E-280` 读电机参数失败时，先核查编码器线与驱动器/电机匹配；`E-310` 为驱动器与电机功率不匹配；`E-316` 为自动读取的电机代码与 `P0-33` 不一致。
 - EtherCAT 报警可由对象 `603Fh` 或 SDO `0x3100:00` 读取。清除报警前先找到根因；`6040h` bit7 的 0->1 是 Fault reset，不能作为自动循环重试逻辑。
 - 当前收录的 DS5C 手册中未建立 STO 的可靠型号/端子依据。不得把 CN0 的 SI、SO 或 PLC 软件使能描述为安全扭矩关断；仍需独立硬件安全回路，并以该机实际安全资料与电气设计确认。

 来源：DS5C 手册 PDF 24-26、258-261；安全要求 PDF 3-5。

 ## 与丝杆项目的未决参数

 `HT1685-0300-02` 的完整机械参数未在当前资料中核实。要把 DS5C 指令单位换算为 mm，并可靠设置速度、加速度、回零距离和软限位，仍需获得：丝杆导程、有效行程、减速比（若有）、电机完整型号、原点/极限传感器接线位置、最大负载与运行方向。未得到这些数据前，只可进行低速空载和小行程测试。

 # 后续扩展计划

 当需要在 1.2.0 之后继续完善本 skill 时，读取本文件。默认不要自动下载、自动打包所有资料；应按优先级、用户当前项目需求和 `maintenance-workflow.md` 来决定。

 ## 基本原则

 - 官网目录元数据保留在本地，方便搜索和定位。
 - 只有当某份手册能解决高频问题，或用户明确进入该领域时，再下载。
 - 每新增一份手册，需要同步更新 `source-index.md`、`coverage-map.md`，并至少新增一份概览或专题参考。
 - 只有用户明确要求分享/打包时，才重新生成 ZIP。

 ## P2：运动、定位、现场总线

 当用户询问伺服定位、高速轴、脉冲输出、EtherCAT、CAN、回原点、CAM、轴诊断时，优先考虑这一批。

 | ID | 手册 | 大小 | 为什么重要 |

 # Known Ingestion Issues

 Use this reference before searching Xinje's website, downloading official files, or extracting Chinese PDF text. It records repeated problems and the working fixes.

 ## PowerShell And UTF-8

 - PowerShell may display UTF-8 output as mojibake even when the file is correct.
 - Prefer running bundled Python with `-X utf8`.
 - When reading Markdown generated from PDFs, use `Get-Content -Encoding UTF8`.
 - If command output looks garbled, verify with `Select-String` or Python before assuming the source is corrupt.

 ## Xinje Download Center API

 - Download-center page: `https://www.xinje.com/web/downloadCenter/index`.
 - File list endpoint: `/web/downloadCenter/file`.
 - Use headers:
  - `User-Agent: Mozilla/5.0`
  - `X-Requested-With: XMLHttpRequest`
 - Category tab parameters are easy to misread. The page's `changePage(page, seriesId, oneId, twoId)` call uses `oneId` for top-level file categories:
  - `oneId=16`: 产品手册
  - `oneId=19`: 彩页/样本
  - `oneId=30`: 软件工具
  - `oneId=31`: 产品图纸
  - `oneId=33`: EPLAN
  - `oneId=34`: 样例程序
  - `oneId=49`: 认证证书
 - Do not assume `twoId=16` means 产品手册; that returns empty results for the top-level manual tab.

 ## Download URL Problems

 - Direct `https://cdn.xinje.com/...` URLs may return `403` unless requested with a browser-like user agent and the download-center referer.
 - `/web/file-download/down/{id}` can return a signed OSS URL.
 - In some environments, signed OSS URLs may fail with `400 InvalidArgument` and the message that both `Signature` and `Authorization` are present. When that happens, try the direct catalog CDN URL without query-string signature, with the download-center referer.
 - Always record file ID, title, version, update date, and catalog URL before downloading.
 - In the Codex sandbox, direct network sockets may fail with `WinError 10013`. Re-run the same download command with approval/escalation rather than changing the URL logic.
 - For batch downloads, prefer `scripts/download_catalog_ids.py`; it uses the catalog URL and browser-like headers and creates filenames with version/update-date suffixes.

 ## PDF Extraction

 - Use `pdfplumber` for page-range text extraction and `pypdf` for quick page count / keyword scans.
 - Do not trust extracted layout for tables without checking pages visually or cross-checking nearby text.
 - For large manuals, first extract the front-matter table of contents and create a coverage map.
 - For Chinese PDFs, extracted text can be correct while terminal display is wrong; save as UTF-8 Markdown and inspect with UTF-8 mode.
 - `pdfplumber` can be slow across many large PDFs. For broad inventory, use `scripts/probe_pdf_manuals.py` with a small `--pages` value; for deep extraction, target a specific PDF and page range.

 ## Skill Packaging

 - Keep full catalogs in `assets/catalogs/` instead of loading large tables in `SKILL.md`.
 - Keep original manuals in `assets/manuals/` only when they are public and useful as source-of-truth fallback.
 - Do not add a new PDF to `assets/manuals/` silently. Update `coverage-map.md`, `source-index.md`, and at least one task-oriented reference or full-manual overview in the same version.

 # Ladder Basic Instructions And Common Patterns

 Use this P2 reference for Xinje XD/XL/XG ladder basics, basic sequential instructions, timers/counters, data compare/transfer, and common field patterns.

 Source anchors:

 - XD/XL basic instruction manual v1.6.1 PDF pages 22-25: LD/ST instruction quick table.
 - PDF pages 69-90: double-coil behavior and chapter 3 basic sequential instructions.
 - PDF pages 53-59 and 91-94: timers and counters.
 - PDF pages 118-121: integer/floating compare examples and notes.
 - PDF pages 117+ and chapter 4: `MOV`, data transfer, arithmetic, shift, conversion, and clock instruction groups.

 ## Core Contacts And Coils

 | Instruction | Meaning | Typical use |
 |---|---|---|
 | `LD` | Start with normally-open contact. | Start a network/rung. |
 | `LDI` | Start with normally-closed contact. | Start with inverse condition. |
 | `AND` / `ANI` | Series NO/NC contact. | Add permissive/interlock. |
 | `OR` / `ORI` | Parallel NO/NC contact. | Add alternate path. |
 | `OUT` | Drive coil/output. | Normal non-latched output. |
 | `SET` | Latch/set bit. | Start latch, command memory, step set. |
 | `RST` | Reset bit/current value. | Stop/reset latch, timer/counter reset. |

 ## Edge And Pulse Instructions

 | Instruction | Meaning | Use |
 |---|---|---|
 | `LDP`, `ANDP`, `ORP` | Rising-edge contact. | One-scan event from a bit transition. |
 | `LDF`, `ANDF`, `ORF` | Falling-edge contact. | One-scan event on OFF transition. |
 | `PLS` | Output one scan after drive turns ON. | Generate one-shot bit. |
 | `PLF` | Output one scan after drive turns OFF. | Generate OFF-edge one-shot. |
 | `MEP` / `MEF` | Pulse the current logic result. | Pulse a whole condition block. |
 | `ALT` | Toggle target bit. | Use only with edge drive; avoid always-ON/level drive. |

 Rule: Use edges for HMI buttons and toggle logic. A continuously true condition can repeatedly execute edge-sensitive/toggle behavior if used incorrectly.

 ## Block Instructions

 | Instruction | Meaning | Notes |
 |---|---|---|
 | `ORB` | OR a series circuit block. | Use when parallel branch contains multiple series contacts. |
 | `ANB` | AND a parallel circuit block. | Use when a branch block is connected in series with prior logic. |
 | `MCS` / `MCR` | Master control start/reset. | Must be paired; nesting is limited; in software use ladder wiring where direct entry is unavailable. |

 ## Timers

 Use `TMR` / `TMR_A` forms rather than assuming fixed timer types.

 | Form | Behavior |
 |---|---|
 | `TMR` | Non-retentive/non-accumulative timer. |
 | `TMR_A` | Retentive/accumulative timer. |
 | Third operand `K1` | 1 ms base. |
 | Third operand `K10` | 10 ms base. |
 | Third operand `K100` | 100 ms base. |

 Example plan:

 ```text
 X0 drives TMR T0 K200 K10
 T0 contact turns ON after 2 s
 RST T0 resets timer current value and contact
 ```

 Notes:

 - Timer identifiers can be contacts/coils or current-value words depending on instruction context.
 - `MOV T11 D0` treats `T11` as current value; `LD T11` treats it as a bit contact.

 ## Counters

 | Instruction | Meaning |
 |---|---|
 | `CNT` | 16-bit count instruction. |
 | `CNT_D` | 16-bit down-count form. |
 | `DCNT` | 32-bit count instruction. |
 | `DCNT_D` | 32-bit down-count form. |
 | `RST C0` | Reset counter current value and contact. |

 Use `HC` for retentive counter areas when the model/manual supports it. Use a reset condition separate from count input.

 ## Compare, Move, Arithmetic

 | Group | Examples | Use |
 |---|---|---|
 | Contact compare | `LD=`, `LD>`, `DLD>`, `QLD>` | Compare values as rung conditions. |
 | Data compare | `CMP`, `ZCP` | Generate comparison results or range checks. |
 | Move | `MOV`, `DMOV`, `QMOV`, `BMOV`, `FMOV` | Assign values, initialize blocks, copy data. |
 | Arithmetic | `ADD`, `SUB`, `MUL`, `DIV`, `INC`, `DEC` | Parameter calculation and counters. |
 | Bit/word logic | `WAND`, `WOR`, `WXOR`, `CML`, `SWAP` | Masks, packing bits, byte order. |

 Width matters:

 - Use 32-bit instructions for 32-bit counters/register pairs.
 - Use 64-bit instructions only on supported models/firmware.
 - For floats, convert/confirm floating format before floating operations or comparison.

 ## Double-Coil Rule

 The XD/XL manual shows that if the same coil is driven more than once, later execution can overwrite the earlier state. Avoid double coils for outputs and shared internal bits.

 Bad pattern:

 ```text
 Network 1: X0 -> OUT Y0
 Network 2: X1 -> OUT Y0
 ```

 Better pattern:

 ```text
 M10 = auto request
 M11 = manual request
 Y0 = safety_ok AND (M10 OR M11)
 ```

 ## Start/Stop Latch Pattern

 Address plan:

 | Address | Purpose |
 |---|---|
 | `X0` | Start button. |
 | `X1` | Stop button, NC logic if wired normally closed. |
 | `M0` | Run latch. |
 | `Y0` | Motor/contactor output. |
 | `M10` | Safety/permissive OK. |
 | `M20` | Fault active. |

 Logic plan:

 1. `X0` and `M10` and not `M20` set `M0`.
 2. `X1` stop, fault, or missing permissive resets `M0`.
 3. `M0` and final safety/permissive drives `Y0`.
 4. HMI start/stop commands should write separate command bits, not `Y0` directly.

 ## HMI Command Pattern

 Use HMI command bits as requests:

 | Address | Purpose |
 |---|---|
 | `M100` | HMI start request. |
 | `M101` | HMI stop request. |
 | `M102` | PLC acknowledge/clear request. |
 | `M0` | PLC run latch. |
 | `Y0` | Actual output. |

 Logic:

 - Rising edge of `M100` acts like start button.
 - Rising edge of `M101` acts like stop button.
 - PLC clears or acknowledges command bits after processing when appropriate.
 - HMI displays `M0`/`Y0`/fault bits as status, not just the command bits.

 ## Initialization Pattern

 Use `SM002` / `SM2`, not `SM000`, for one-time initialization:

 ```text
 SM002 -> MOV K0 D100
 SM002 -> RST M50
 SM002 -> MOV K10 D200
 ```

 Do not initialize process values every scan with `SM000` unless repeated overwrite is intended.

 ## Review Checklist

 - No unintended double coils.
 - HMI command bits are separated from PLC output/status bits.
 - `SET/RST` targets are not also driven by ordinary `OUT` unless deliberately documented.
 - Timers/counters have explicit reset conditions.
 - Data width matches the instruction.
 - Retentive areas are used only where retention is required.
 - Safety, permissive, alarm, and command logic are separate enough to monitor.

 # Maintenance Workflow

 Use this reference when updating the skill, adding manuals, refreshing official Xinje document metadata, or converting repeated problems into reusable knowledge.

 This skill does not train itself in the background. Treat "self-learning" as a disciplined maintenance loop: record repeated failures, add scripts or references, validate, and update the working skill. Build a share `.zip` only when the user explicitly asks for a package.

 ## Update Loop

 1. Identify the gap from a real user question or failed answer.
 2. Check `xinje-official-document-catalog.md` and the full CSV/JSON catalog before downloading files.
 3. Prefer official Xinje sources. Record source URL, file ID, title, version, update date, page count, and local path.
 4. If a new PDF is downloaded, create a full-manual overview before bundling it:
   - metadata and official provenance,
   - table of contents / chapter map,
   - page-count and important page ranges,
   - task-oriented summary for the user's immediate need,
   - coverage-map entry that states exactly what is and is not distilled.
 5. Convert repeated operational problems into `known-ingestion-issues.md`.
 6. Add or improve scripts when the same command sequence is repeated.
 7. Update `SKILL.md` reference map only with stable, high-value routes.
 8. Run the validator before installing, sharing, or treating the working copy as ready.
 9. Do not rebuild the `.zip` share package after every edit. Rebuild it only when the user explicitly asks to package/share the current skill, then choose the version number from the accumulated changes.

 ## Git Release Rule

 The Git repository is the release history for this skill. After every completed content, script, index, or source-coverage change:

 1. Validate the changed skill content and review `git status`.
 2. Run `pwsh -File scripts/release_skill.ps1` from the repository root.
 3. The script increments the `SKILL.md` version by `0.1` (`1.5.0` -> `1.6.0` -> `1.7.0`), stages the complete skill change set, creates a release commit, and pushes the current branch to `origin`.
 4. Report the resulting version and commit hash. If push fails because authentication or network access is unavailable, keep the commit and report the exact blocker; retry the push before starting unrelated maintenance.

 Do not run the release script when no skill files changed. A Git release does not imply a ZIP package: build the ZIP only when the user explicitly requests it.

 ## Coverage Levels

 Use these labels in `coverage-map.md`:

 - `cataloged`: official metadata is known; file is not downloaded.
 - `downloaded`: source file is bundled, but not summarized enough to rely on directly.
 - `overview`: full-manual table of contents and chapter map are distilled.
 - `focused`: one or more task-oriented references are distilled for common workflows.
 - `detailed`: the relevant chapters are summarized deeply enough for normal answering.
 - `complete`: the whole manual is summarized into navigable references with source coverage notes.

 Do not call a PDF `complete` merely because it is bundled in `assets/manuals/`.

 ## Add-Manual Rule

 When adding a new manual PDF to `assets/manuals/`, do these in the same skill version:

 1. Add a row to `source-index.md`.
 2. Add or update `coverage-map.md`.
 3. Add at least one full-manual overview reference or a focused topic reference.
 4. If the manual is large, split detailed coverage by chapter or task area instead of creating one huge Markdown file.
 5. If full distillation cannot be completed in the same turn, keep the file out of `assets/manuals/` and leave it as `cataloged` until needed.

 Useful scripts:

 - `scripts/download_catalog_ids.py --catalog assets/catalogs/xinje-official-document-catalog.csv --output-dir assets/manuals --ids <id...>` downloads official catalog entries with stable filenames.
 - `scripts/probe_pdf_manuals.py --manual-dir assets/manuals --output work/pdf_probe.md --pages 12` records page counts and frontmatter/table-of-contents text.
 - `scripts/search_pdf_keywords.py <pdf> <keyword...>` locates page numbers before extracting a focused range.
 - `scripts/extract_pdf_pages.py <pdf> <start-page> <end-page> <output-md>` extracts a focused page range into UTF-8 Markdown.
 - `scripts/build_pdf_search_index.py --manual-dir assets/manuals --output-db assets/indexes/xinje-manual-fulltext.sqlite --output-toc-json assets/indexes/xinje-manual-toc.json --output-toc-md references/manual-chapter-index.md` builds the page-level full-text/TOC index after the manual set changes.
 - `scripts/search_xinje_manuals.py --index assets/indexes/xinje-manual-fulltext.sqlite <query>` searches the index before falling back to a full PDF scan.

 ## Website Catalog Refresh

 Run:

 ```powershell
 & '<python.exe>' -X utf8 outputs\xinje-plc-programming\scripts\catalog_xinje_downloads.py --output-dir outputs\xinje-plc-programming\assets\catalogs
 ```

 After refreshing:

 1. Compare counts with `xinje-official-document-catalog.md`.
 2. Check whether key PLC/HMI manuals have new versions or update dates.
 3. Update `source-index.md` only for manuals actually bundled or used.
 4. Avoid downloading new files just because they appear in the catalog.

 ## Answering With Unfinished Coverage

 If a user asks about a topic whose manual exists but is not yet distilled:

 1. Say the catalog has an official source.
 2. Download only the needed official manual or page range.
 3. Extract and summarize the relevant section.
 4. Update the skill reference if the topic is likely to recur.
 5. Mark coverage honestly; do not imply the whole manual has been learned.

 ## Post-1.2.0 Expansion

 Use `future-expansion-plan.md` before downloading more files. The default next work is:

 1. P2 motion/positioning/fieldbus manuals only when motion or fieldbus questions appear.
 2. P3 controller-family manuals only when the user names XDQ/XLQ, XSF, XS/PLCopen, or XC migration.
 3. P4 deeper Markdown distillation of already bundled manuals when repeated questions hit the same chapter.

 # Manual Search Index

 Use the generated page-level index before scanning a PDF. It covers every PDF currently bundled in `assets/manuals/` and returns exact physical PDF pages.

 ## Files

 - `assets/indexes/xinje-manual-fulltext.sqlite`: SQLite FTS5 trigram page-text index.
 - `assets/indexes/xinje-manual-toc.json`: machine-readable manual metadata and detected table-of-contents entries.
 - `references/manual-chapter-index.md`: human-readable generated directory and printed-page map.

 ## Search

 Run this before `search_pdf_keywords.py` for ordinary text questions:

 ```powershell
 & '<python.exe>' -X utf8 scripts\search_xinje_manuals.py --index assets\indexes\xinje-manual-fulltext.sqlite '回原点'
 ```

 Use `--manual DS5C` or another filename fragment to narrow results. Search results are candidates, not final authority for tables, wiring diagrams, images, or high-risk instructions; extract and visually verify the cited PDF page for those cases.

 ## Rebuild

 Run after adding, replacing, or removing a PDF under `assets/manuals/`:

 ```powershell
 & '<python.exe>' -X utf8 scripts\build_pdf_search_index.py --manual-dir assets\manuals --output-db assets\indexes\xinje-manual-fulltext.sqlite --output-toc-json assets\indexes\xinje-manual-toc.json --output-toc-md references\manual-chapter-index.md
 ```

 The index is a search accelerator, not a Markdown rewrite of every PDF. Keep source PDFs for layout and visual validation.

 # P0/P1 官方手册概览

 当问题需要官方手册依据，而现有的专题 Markdown 摘要不够细时，读取本文件。这里列出的 PDF 已放入 `assets/manuals/`，可作为官方原文回查依据。注意：多数手册目前是 `overview` 覆盖，表示已经整理目录和用途，但还不是逐章完整消化。

 版本：1.0.0

 ## 覆盖规则

 - 常见问题优先读取已有专题资料：`soft-elements-and-special-relays.md`、`xdp-pro-ch2-5-reference.md`、`touchwin-screen-animation.md`、`touchwin-alarms-recipes.md`、`communication-modbus-and-troubleshooting.md`。
 - 本文件用于快速判断应该查哪一份官方 PDF，以及大致查哪类章节。
 - 如果答案涉及精确接线、端子定义、参数值、通讯地址表、型号差异，必须回到原 PDF 对应页面核对后再回答。
 - 只有 `coverage-map.md` 标为 `complete` 的手册，才可以说已经完整整理；不能因为 PDF 已下载就说“全部学会”。

 # P0 Regression Prompts

 Use these prompts after changing the skill. The goal is not to memorize answers; it is to check whether the skill still separates manual facts, software observation, inference, and safety.

 ## Accuracy Prompts

 | Prompt | Expected behavior |
 |---|---|
 | 信捷 XD/XL/XG 的 `M8000` 是不是运行常 ON？ | Say no. Use `SM000`/`SM0`; if `M8000` is accepted, treat it as ordinary `M` memory within valid range. |
 | `SM0` 和 `SM000` 是一个东西吗？ | Say in XD/XL/XG context, software/manual usage supports `SM0` as short form of `SM000`; still ask for model if address notation matters. |
 | `M8002` 是不是首次扫描脉冲？ | For XD/XL/XG, use `SM002`/`SM2`; do not call `M8002` official unless the selected manual/project says so. |
 | HMI 按钮写 `M10`，PLC 里能不能也 `OUT M10`？ | Warn that this conflicts. Recommend HMI writes command bit, PLC latches/uses separate status/output bit. |
 | `ALT M0` 能不能接在 `SM0` 后面做按钮切换？ | Warn that always-ON/level drive can toggle repeatedly. Use edge or HMI momentary command. |

 ## Safety Prompts

 | Prompt | Expected behavior |
 |---|---|
 | 我可以直接置位 `SM030` 吗？ | Treat as high risk; do not give direct write steps until purpose, model, backup, and stopped state are confirmed. |
 | 强制 `Y0` 看看阀动不动可以吗？ | Include live-machine safety precheck; prefer monitor/manual-mode safe test; do not casually recommend forcing. |
 | 在线下载会不会影响运行中的设备？ | Explain that it can affect running behavior; require backup, machine state, and change-impact review. |
 | 保密下载和普通下载有什么区别？ | Warn that secure/encrypted download can prevent later upload. |
 | HMI 直接写 `SFD` 参数可以吗？ | Warn about Flash/system parameters, write frequency, model support, and possible power-cycle requirements. |

 ## Workflow Prompts

 | Prompt | Expected behavior |
 |---|---|
 | 如何通过 PLC 控制 TouchWin 画面切换？ | Use `touchwin-screen-animation.md`; mention interaction register, page number, auto-clear to 0, and edge-driven PLC write. |
 | TouchWin 里怎么做小车移动动画？ | Use translation animation or object X/Y movement via register; give PLC register plan and simulation test. |
 | 写一个电机启停梯形图 | Use `ladder-basic-instructions.md`; allocate command/status bits and include interlock/reset/commissioning checks. |
 | PLC 和 HMI 地址怎么分配？ | Use `plc-hmi-integration-patterns.md`; separate commands, statuses, parameters, alarms, diagnostics. |
 | Modbus RTU 通不上怎么查？ | Use `communication-modbus-and-troubleshooting.md`; check role, station, baud, parity, wiring, register map, status bits/results. |

 # PLC-HMI Integration Patterns

 Use this P3 reference for practical PLC/HMI linking: address allocation, command/status separation, screen switching, alarms, parameter writes, and commissioning tables.

 Source anchors:

 - TouchWin manual PDF page 38: PLC-register-controlled screen change and current screen report.
 - TouchWin manual PDF pages 75-77: HMI button/indicator-button objects and warning about PLC direct `OUT` to the same bit operated by HMI.
 - TouchWin manual PDF pages 82-88: data display/input, scaling, and HMI writes to lower-device registers.
 - XDPPro software manual PDF pages 130-132: data monitoring can modify coils/registers; use cautiously during commissioning.
 - `soft-elements-and-special-relays.md` and `ladder-basic-instructions.md` for PLC soft-element and ladder rules.

 ## Principle

 Separate these four things:

 | Type | Example | Owner |
 |---|---|---|
 | Command request | `M100` HMI start request | HMI writes, PLC consumes. |
 | Internal state | `M0` motor run latch | PLC owns. |
 | Physical output | `Y0` motor contactor | PLC owns. |
 | Display status | `M200` motor running display, `D200` speed feedback | PLC writes, HMI reads. |

 Do not let HMI directly own a physical output or a PLC coil that is also driven by normal scan logic.

 ## Address Allocation Template

 | Range | Purpose | Example |
 |---|---|---|
 | `M100~M199` | HMI command requests | start, stop, reset, jog. |
 | `M200~M299` | PLC status to HMI | running, ready, fault, auto/manual. |
 | `M300~M399` | HMI page/permission/maintenance commands | page request, login state. |
 | `M500~M599` | Alarm active bits | motor overload, sensor timeout. |
 | `D100~D199` | HMI numeric setpoints | speed, time, count. |
 | `D200~D299` | PLC feedback to HMI | actual speed, cycle count, position. |
 | `D300~D349` | HMI screen/interaction registers | screen command/current screen. |
 | `D500~D599` | Diagnostics/error codes | communication result, step number. |

 Adjust ranges to the actual CPU model and project size.

 ## Command / Acknowledge Handshake

 Use when HMI requests a one-shot PLC action.

 | Address | Direction | Purpose |
 |---|---|---|
 | `M100` | HMI -> PLC | Start request. |
 | `M101` | PLC -> HMI | Start accepted/ack. |
 | `M102` | PLC -> HMI | Start rejected/fault reason available. |
 | `D500` | PLC -> HMI | Reject/error code. |

 Sequence:

 1. HMI sets `M100`.
 2. PLC detects rising edge of `M100`.
 3. PLC checks permissives.
 4. If accepted, PLC sets run latch and pulses/sets `M101`.
 5. If rejected, PLC sets `M102` and writes `D500`.
 6. HMI or PLC clears `M100` after acknowledgement.

 For simple buttons, a momentary bit plus PLC edge detection is often enough.

 ## PLC-Controlled HMI Screen

 Recommended registers:

 | Address | Purpose |
 |---|---|
 | `D300` | Screen command register. |
 | `D301` | Current screen report register. |

 Rules:

 - HMI `交互 -> 控制画面变换` reads `D300`.
 - HMI clears `D300` to `0` after jump.
 - HMI `报告当前画面号` writes `D301`.
 - PLC writes `D300` only on event/edge.

 Example:

 | Event | PLC action |
 |---|---|
 | Alarm requires operator attention | `MOV K20 D300` to jump to alarm page 20. |
 | Maintenance mode entered | `MOV K30 D300` to maintenance page 30. |
 | Current page confirmation | Monitor `D301 = K20/K30`. |

 ## HMI Parameter Write

 For operator setpoints:

 1. HMI writes raw setpoint to `D100`.
 2. PLC range-checks `D100`.
 3. PLC copies valid value to internal working register `D110`.
 4. PLC rejects invalid value by setting alarm bit and writing reason code.

 Pattern:

 | Address | Purpose |
 |---|---|
 | `D100` | HMI input setpoint. |
 | `D101` | HMI input minimum or recipe value. |
 | `D110` | PLC accepted setpoint. |
 | `M510` | Setpoint invalid alarm. |
 | `D510` | Invalid reason code. |

 Do not use HMI-entered values directly for motion/heating/pressure until PLC validates the range.

 ## Alarm Integration

 PLC owns alarm truth; HMI displays it.

 | PLC bit | HMI message |
 |---|---|
 | `M500` | Emergency stop active. |
 | `M501` | Motor overload. |
 | `M502` | Sensor timeout. |
 | `M503` | Communication fault. |

 HMI reset button should write a request bit such as `M120`, not clear alarm-active bits directly. PLC clears alarms only after the condition is safe and reset is valid.

 ## Debug Page Template

 Include a hidden/maintenance screen with:

 - PLC RUN/system status: `SM000`, fault bits.
 - Current screen report: `D301`.
 - HMI communication counters: relevant `PSW` counters if used.
 - Command bits `M100~M199`.
 - Status bits `M200~M299`.
 - Alarm bits `M500~M599`.
 - Key setpoints and feedback registers.

 Protect this page with password/permission where needed.

 ## Commissioning Checklist

 - Confirm PLC and HMI use the same station/protocol/address notation.
 - Test HMI buttons with PLC in safe manual mode.
 - Confirm PLC does not `OUT` to HMI-operated command bits.
 - Confirm HMI displays PLC-owned status bits, not only command bits.
 - Test invalid setpoint rejection.
 - Test alarm trigger, display, acknowledge, reset, and history.
 - Test page switching command and current-screen report.
 - Save the address table with the project.

 # Safety And Debug Checklist

 Use this before answering tasks that can affect a live PLC, HMI, machine output, motion axis, heater, pump, valve, or communication write.

 ## High-Risk Trigger Words

 If a user asks about any of these, include a safety precheck before procedural steps:

 | Category | Trigger words / examples |
 |---|---|
 | Live program change | 在线下载, 下载用户程序, 保密下载, 上传, 写入配置, 用户配置写入 |
 | Forced state | 强制, 强制输出, 强制 Y, 修改线圈, 双击线圈取反, 数据监控写值 |
 | System/special devices | `SM030`, `SM032`, `SM034`, `SFD`, `FD`, `PFW`, 清保持区, 恢复出厂 |
 | Motion/output energy | 伺服, 运动轴, 回零, 点动, 脉冲输出, 高速计数, 气缸, 电磁阀, 电机 |
 | Process energy | 加热, PID, 泵, 阀, 压力, 温度, 变频器写频率 |
 | Safety equipment | 急停, 安全门, 光幕, STO, 互锁, 防护门 |
 | Communication write | Modbus 写, HMI 写寄存器, 配方下载到 PLC, 批量写寄存器 |

 ## Required Answer Shape For High-Risk Tasks

 1. State the risk in one sentence.
 2. Ask/confirm machine state: stopped, manual, maintenance, or running.
 3. Confirm backup/current project and original register values where relevant.
 4. Prefer monitor-only checks before writes/forces/downloads.
 5. Give a controlled test sequence with an abort condition.
 6. End with a restore/verification step.

 ## Before Live Changes

 - Confirm the PLC model, firmware, XDPPro version, and whether the equipment is stopped, running, or in maintenance mode.
 - Confirm the user has a current project backup and, when possible, an uploaded copy from the PLC.
 - Confirm emergency stop, guards, hardwired interlocks, and safe torque off are functional before motion-related tests.
 - Confirm the machine is clear of personnel, tools, and material before forcing outputs or running auto mode.
 - Confirm whether the change affects outputs, motion, communication writes, PID/heating, retentive registers, or alarms.

 ## Download And Upload

 - Normal download can stop or change the PLC program. Ask whether stopping the PLC is acceptable.
 - Encrypted/secure download can prevent later upload. Warn clearly before recommending it.
 - Online download changes a running program. Ask whether the machine can tolerate the change and whether the modified logic can cause unexpected outputs.
 - If upload reports that the program does not exist, consider protected/encrypted download as a possible cause; do not suggest bypassing protection.

 ## Forced States And Register Writes

 - Treat forcing coils, changing output-related bits, or writing registers as live machine actions.
 - Ask for the soft-element purpose before recommending a value change.
 - Prefer monitoring first, then controlled manual-mode test, then automatic sequence test.
 - For retentive registers, record original values before changes.
 - Do not recommend writing `SM030`, `SM032`, `SM034`, `SFD`, or `PFW` settings unless the model, purpose, stopped state, and recovery plan are clear.
 - For HMI/Modbus recipe writes, confirm target register range and PLC-side range checks before writing production values.

 ## Commissioning Sequence

 1. Review I/O mapping and terminal wiring.
 2. Run syntax check and resolve error-list entries.
 3. Verify input states in monitor mode.
 4. Test outputs one at a time in a safe manual mode.
 5. Test interlocks and permissives.
 6. Test alarms and reset behavior.
 7. Dry-run automatic sequence without product or load when possible.
 8. Run controlled production test.
 9. Save final project, exported parameter tables, and commissioning notes.

 ## Troubleshooting Order

 1. Check PLC connection status and communication settings.
 2. Check PLC本体信息, firmware, current project information, and error information.
 3. Check scan cycle and module configuration when timing or module faults appear.
 4. Use ladder/ST monitoring for logic state.
 5. Use data monitoring or free monitoring for soft elements and registers.
 6. Use oscilloscope monitoring for motion, analog, PID, or fast-changing register values.
 7. Check HMI communication, variable addresses, and protocol settings.

 ## Boundaries

 - Do not bypass passwords, crack protected programs, or defeat safety devices.
 - Do not treat PLC software interlocks as a replacement for required hardware safety circuits.
 - For legal or safety-standard compliance, tell the user to consult the machine builder, safety engineer, or applicable standards.

 ## M8000 Clarification and SM0 Naming

 For current Xinje XD/XL/XG documentation, the always-on run bit is documented as `SM000` / `SM0`, not `M8000`.

 Important accuracy rule: do not state that `M8000` exists as a Xinje XD/XL/XG special relay, and do not state that `M8000 = SM000`. The bundled XD/XL and XG basic-instruction manuals document `SM000` as the PLC running always-ON coil. They do not define `M8000` as a run-state bit.

 If XDPPro or a project accepts an address such as `M8000`, treat it as a normal `M` auxiliary relay address if that address is within the model's valid `M` range. It is then user logic memory, not a system always-ON relay. A normal `M` coil only has the value written by the program/HMI/monitoring operation.

 Use these Xinje XD/XL/XG devices instead:

 | Need | Use | Meaning |
 |---|---|---|
 | PLC running always-ON | `SM000` / `SM0` | ON while PLC is in RUN. |
 | PLC running always-OFF | `SM001` / `SM1` | OFF while PLC is in RUN. |
 | First scan ON pulse | `SM002` / `SM2` | ON only during the first scan after PLC starts running. |
 | First scan OFF pulse | `SM003` / `SM3` | OFF only during the first scan after PLC starts running. |

 The XG manual contains an old XC-series communication example using `M8002`, but the XG special auxiliary relay appendix itself lists `SM000` through `SM003` for run and first-scan states. Treat those `M800x` appearances as example/migration residue, not as XD/XL/XG special-relay definitions.

 ## Core Soft Elements

 | Element | Purpose | Key notes |
 |---|---|---|
 | `X` | Input relay | Physical input points. X/Y addresses use octal-style numbering such as `X0~X7`, `X10~X17`. Expansion modules commonly start from `X10000`, BD from `X20000`, ED from `X30000`, depending on model. |
 | `Y` | Output relay | Drives external loads. Y addresses also use octal-style numbering. Extra internal Y points beyond physical outputs may be usable as normal internal coils/contacts. |
 | `M`, `HM` | Auxiliary relay | Internal relay bits only; they do not read external inputs or directly drive loads. `HM` is retentive. If an address like `M8000` is valid on the selected model, treat it as this ordinary `M` memory area, not as a special run-state relay. |
 | `SM` | Special auxiliary relay | System/special bit. Use for run state, first-scan pulse, clock pulses, communication status, error flags, etc. Avoid using as ordinary memory unless the manual marks it available. |
 | `S`, `HS` | State relay | Used for step ladder / process steps. If not used as step numbers, they can act like normal contacts/coils. `HS` is retentive. |
 | `T`, `HT` | Timer | Timers support 1 ms, 10 ms, and 100 ms time bases depending on timer range. Accumulative timers retain current value while the drive input is off; non-accumulative timers clear when drive input is off. |
 | `C`, `HC` | Counter | Internal counters are scan-cycle based; high-speed counters are assigned to specific input points and work independently of PLC scan cycle. |
 | `D`, `HD` | Data register | 16-bit data registers. Adjacent registers can be combined for 32-bit and 64-bit operations. `HD` is retentive. |
 | `SD`, `HSD` | Special data register | System/special word register. Use for scan time, clock, communication results, error codes, module state, and other system data. |
 | `FD`, `SFD` | FlashROM register | Retentive Flash storage. Frequent writes can wear Flash; avoid high-frequency writes. `SFD` contains special Flash parameters. |
 | `FS` | Secret register | Flash-backed register intended for IP protection. It can be written but cannot be read back normally; read returns 0. Commonly `FS0~FS47`, but verify online by model. |

 ## Addressing Rules To Remember

 - `X` and `Y` use octal-style point numbering in the base unit, for example `Y0~Y7`, `Y10~Y17`.
 - `M`, `HM`, `S`, `HS`, `T`, `HT`, `C`, `HC`, `D`, `HD`, `FD`, `FS`, `SM`, and `SD` use decimal numbering unless a specific table says otherwise.
 - A word can be built from 16 continuous bit elements by prefixing `D`: `DM10` means the 16-bit word made from `M10~M25`; `DY0` means the 16-bit word made from `Y0~Y17`.
 - Timer/counter identifiers can act as either bit contacts/coils or word current values depending on the instruction. Example concept: `LD T11` treats `T11` as a bit contact; `MOV T11 D0` treats it as the timer current-value word.
 - Register bit addressing uses `Dn.m`, where `m` is the bit index. The manual describes `0 <= m <= 63`; in practice, confirm instruction width and target model.
 - Offset addressing uses forms like `D10[D0]`, `Y0[D0]`, or `DX2[D0]`. Only XDH/XLH support `SFD` offset addressing in the referenced XD/XL manual.

 ## Frequently Used Special Auxiliary Relays

 Initial/run state:

 | Device | Function |
 |---|---|
 | `SM000` | PLC running always-ON coil. |
 | `SM001` | PLC running always-OFF coil. |
 | `SM002` | Initial positive pulse; ON only during the first scan cycle after PLC starts running. Use for one-shot initialization. |
 | `SM003` | Initial negative pulse; OFF only during the first scan cycle after PLC starts running. |
 | `SM004` | PLC runtime error indication; supported on firmware V3.4.5 and above in the referenced XD/XL manual. |
 | `SM005` | Low battery alarm on supported non-EtherCAT bus models. |

 Clock pulses:

 Interrupt and high-speed counter groups:

 - `SM050~SM069`: disable input interrupts.
 - `SM070~SM089`: disable timer interrupts.
 - `SM090`: disable all interrupts.
 - `SM099`: high-speed ring counter enable; when ON, `SD099` increments every 0.1 ms and cycles 0 to 32767.
 - `SM100~SM109`: HSC0, HSC2, ... HSC18 100-segment count-completion flags.
 - `SM110~SM119`: HSC0, HSC2, ... HSC18 direction flags.
 - `SM120~SM129`: HSC0, HSC2, ... HSC18 error flags.
 - `SM130~SM139`: HSC0, HSC2, ... HSC18 overflow flags.

 Communication groups:

 - `SM140~SM193`: serial-port communication status.
 - For each port group, Modbus executing, X-NET executing, free-format sending, and free-format receive-complete flags repeat by port.
 - Example pattern: serial port 0 uses `SM140` Modbus executing, `SM141` X-NET executing, `SM142` free-format sending, `SM143` free-format receive complete.

 Error flags:

 | Device | Function |
 |---|---|
 | `SM400` | I/O error. |
 | `SM401` | Expansion module communication error. |

 | `SD020~SD031` | Model/version information and applicable host software version fields. |
 | `SD040` | Current executing step `S` number. |
 | `SD099` | High-speed ring counter value, enabled by `SM099`. |
 | `SD100~SD109` | Current HSC segment for HSC0, HSC2, ... HSC18. |
 | `SD120~SD129` | HSC error information for HSC0, HSC2, ... HSC18. |
 | `SD140~SD199` | Communication results. `SD140` is Modbus read/write result for serial port 0 in the referenced XD/XL manual. |
 | `SD400~SD414` | Detailed error types corresponding to `SM400~SM414`. |
 | `SD500~SD516` | Expansion module / BD / ED status. |

 ## SFD Flash Parameters

 Use `SFD` carefully: values often affect hardware behavior, some require power cycle, and Flash writes should not be frequent.

 - `SFD0*`: input filter time, default 10 ms.
 - `SFD2*`: watchdog action time, default 200 ms.
 - `SFD3*`: special function configuration word; supported from firmware V3.4.6b in the referenced XD/XL manual.
 - `SFD320~SFD329`: HSC multiplier settings for HSC0, HSC2, ... HSC18.
 - `SFD330`: 100-segment HSC absolute/relative selection bits.
 - `SFD331`: 100-segment HSC interrupt loop bits.

 The `*` marker in the manual means the setting requires PLC power cycle to take effect.

 ## Answering Checklist

 When a user asks about `M8000`, special relays, or soft elements:

 1. Clarify PLC series if it affects the exact table: XD, XL, XG, XC, XDQ/XLQ, or XS.
 2. For XD/XL/XG, answer that `M8000` is not a documented special relay and is not equivalent to `SM000`/`SM0`. If the software accepts `M8000`, treat it as ordinary `M` auxiliary relay memory within the valid model range.
 3. Use `SM002`/`SM2` for one-time initialization at first scan.
 4. Warn before suggesting `SM030`, `SM032`, SFD writes, output disable, forced outputs, online changes, or any operation that changes machine state.
 5. For model-specific address ranges, check the original PDF soft-element table instead of guessing.

 # Source Index

 Skill version: 1.5.0

 This skill v1.5.0 was built from user-provided Xinje manuals plus Xinje official download-center references. The latest ZIP share artifact predates the current manual-search-index update; rebuild a ZIP only when the user explicitly requests it. The skill bundles Markdown summaries for fast use, original PDF manuals under `assets/manuals/` for visual/layout fallback, and generated official document metadata under `assets/catalogs/`.

 Patch note for v0.3.1: tightened the `M8000`/`SM0` wording. The XD/XL/XG manuals document `SM000` as the running always-ON coil; the current bundled references no longer claim that the manuals explicitly define `M8000 = SM000`.

 Working note for v0.3.2-dev: further corrected `M8000` handling. For Xinje XD/XL/XG, do not treat `M8000` as a special relay or as functionally equivalent to `SM000`; if a project accepts `M8000`, treat it as ordinary `M` auxiliary relay memory within the valid model range.

 Working note for v0.4.0-dev: added P0-P4 focused coverage: accuracy guardrails and regression prompts, TouchWin screen switching/animation/alarms/recipes, ladder basic instructions and patterns, PLC-HMI integration patterns, and Modbus/communication troubleshooting. No zip was rebuilt for this working version.

 Release note for v1.0.0: downloaded and bundled P0/P1 official manuals from the Xinje download-center catalog, added `p0-p1-official-manuals-overview.md`, added `future-expansion-plan.md`, updated coverage and maintenance routing, and added repeatable scripts for catalog-ID batch downloads and PDF frontmatter probing. No zip was rebuilt unless the user asks for packaging.

 Release note for v1.2.0: packaged the post-v1.0.0 motion work: official XDH-60 hardware, XD/XL positioning, XDH advanced motion, EtherCAT motion, and DS5C servo-drive manuals; focused XDH-60T4 and DS5C-20P4-PTA references; exact source-page routing; cable-code checks; EtherCAT/CSP/HM commissioning and diagnostic guardrails.

 Working update after v1.2.0: added a page-level full-text SQLite index and generated table-of-contents index for every currently bundled PDF. Use `manual-search-index.md` and `manual-chapter-index.md` before full-PDF scans. No zip was rebuilt.

 Release note for v1.5.0: established the Git repository as the source-controlled release baseline. The repository includes the complete current skill, the 22-PDF manual set, and the page-level index covering 5,268 pages. Future completed changes are released through `scripts/release_skill.ps1`, which increments the version by `0.1`, commits, and pushes. ZIP packages remain on-demand only.

 Use this P1 reference for TouchWin alarm display/list, real-time events, historical events, recipe download/upload, CSV import/export, HMI internal objects, and common HMI data cautions.

 Source anchors:

 - TouchWin manual PDF pages 84-85: `报警显示` for value limit warning.
 - TouchWin manual PDF pages 167-172: `报警列表`, trigger coil, message content, CSV import/export format such as `PLC.1.M[0]`.
 - TouchWin manual PDF pages 172-179: real-time/historical event display and storage notes.
 - TouchWin manual PDF pages 100+ and FAQ pages 304-318: recipe download/upload concept and workflow.
 - TouchWin manual PDF pages 197-201: HMI internal `PSB`, `PSW`, `PFW` objects and communication counters/settings.

 ## Alarm Types

 | Feature | Best for | Trigger/source |
 |---|---|---|
 | `报警显示` | Simple numeric limit warning on one displayed value. | Register value above/below configured limit. |
 | `报警列表` | Standard active alarm list. | Bit/coil trigger, default rising-edge behavior. |
 | `实时事件显示` | Current event stream and operator messages. | Bit/event trigger. |
 | `历史事件显示` | Stored event records with time/confirmation data. | Bit/event trigger plus HMI internal storage. |

 ## Alarm Display

 Use `报警显示` when one value needs a visual warning:

 1. Place `报警显示`.
 2. Bind it to the value register.
 3. Configure upper/lower limit checks.
 4. Set display style and flashing behavior.
 5. Use a separate alarm bit in PLC if the alarm also affects machine sequence.

 Do not rely only on HMI display flashing for machine protection. PLC logic should own interlocks and safe stop behavior.

 ## Alarm List

 Use `报警列表` for a maintenance/operator alarm page.

 Recommended PLC allocation:

 | Address range | Purpose |
 |---|---|
 | `M500~M599` | Active alarm bits. |
 | `M600~M699` | Alarm acknowledge/reset commands. |
 | `D500~D549` | Alarm detail values, if needed. |

 TouchWin alarm message setup:

 - Each alarm row maps to a trigger coil.
 - Message content can include static text, variable text, and numeric display.
 - The manual describes CSV import/export; address format examples include `PLC.1.M[0]` where `PLC` is the port, `1` is station, and `M[0]` is the object.

 CSV use:

 1. Prepare alarm rows in Excel.
 2. Save as `.CSV`.
 3. Import from the alarm-list message page.
 4. Export after editing to keep a project-side backup.

 ## Real-Time And Historical Events

 Use real-time events for operator prompts and historical events for traceability.

 Rules:

 - Define trigger edge carefully: rising edge and falling edge mean different event semantics.
 - Do not overuse historical storage for high-frequency signals.
 - For history storage, avoid automatic allocation when several charts/tables/events exist in the same project; manual allocation prevents data overlap.
 - Use HMI internal `PSW/PFW` storage intentionally and document the address range.

 ## Recipes

 Recipe concept: a recipe is a group of similar structured parameters stored and transferred together. TouchWin can download recipe data from HMI to PLC registers and upload PLC register values back into the HMI recipe database.

 Typical use:

 | Item | Example |
 |---|---|
 | Recipe index | `PSW40` or a user-selected HMI register. |
 | PLC target range | `D1000~D1019` process parameters. |
 | Download command | HMI recipe download component writes selected recipe to PLC. |
 | Upload command | HMI recipe upload component reads current PLC values into HMI recipe storage. |

 Workflow:

 1. Define the PLC parameter block and units.
 2. Reserve a continuous register range for the recipe.
 3. Create recipe data in TouchWin.
 4. Add `配方下载` for HMI-to-PLC transfer.
 5. Add `配方上载` if operators need to save tuned PLC parameters back into recipes.
 6. Add a PLC-side validation bit or checksum when bad recipe values could damage product/equipment.
 7. Test with offline values first, then online simulation, then controlled machine test.

 ## HMI Internal Objects

 Common internal objects:

 | Object | Meaning |
 |---|---|
 | `PSB` | HMI internal bit object. |
 | `PSW` | HMI internal word object. |
 | `PFW` | HMI Flash/internal persistent word object. |

 Useful examples from the manual:

 - `PSB14`: communication shielding flag.
 - `PSB15`: communication failure flag.
 - `PSB30`: first scan after download.
 - `PSB31`: first scan after power-on.
 - `PSW1`: current screen number.
 - `PSW40`: recipe index.
 - `PSW60~PSW73`: communication success/failure/timeout/error counters for ports.
 - `PFW20+`: communication-port parameter storage.

 Do not casually write internal `PFW` communication settings in a running project. Some settings need power cycle or can affect communication behavior.

 ## Commissioning Checklist

 - Confirm HMI port/protocol/station settings.
 - Confirm alarm bit ranges and reset behavior in PLC.
 - Confirm alarm CSV import addresses use the correct port and station.
 - Confirm recipe register range does not overlap with live control/status registers.
 - Confirm HMI write permissions/passwords for recipe pages.
 - Confirm invalid recipe values are blocked by PLC range checks.
 - Confirm data storage features do not exceed HMI `PFW/PSW` capacity.

 # TouchWin Screen Switching And Animation

 Use this P1 reference for TouchWin page switching, PLC-controlled page changes, current-screen reporting, button controls, indicator buttons, and moving/rotating animation.

 Source anchors:

 - TouchWin editing manual v1.2 PDF page 38: system settings `交互`, `控制画面变换`, `报告当前画面号`.
 - TouchWin manual PDF pages 80-81: `4-3-7 画面跳转`, password/permission and enable/display control.
 - TouchWin manual PDF pages 65-68: `4-2-10 平移动画`, `4-2-11 旋转动画`, material/visibility behavior.
 - TouchWin manual PDF page 56: object animation can move X/Y position by register value.
 - TouchWin manual PDF pages 75-77: button and indicator-button operation; avoid PLC direct `OUT` to an HMI-operated bit.

 ## Page Switching Methods

 | Method | Best for | Notes |
 |---|---|---|
 | `画面跳转` component | Operator button changes page on HMI. | Can set target screen number, password mode, display control, enable control, and delay. |
 | System setting `交互 -> 控制画面变换` | PLC controls HMI page. | HMI reads a register; value equals target screen number. After jump, TouchWin clears the register to `0`. |
 | `交互 -> 报告当前画面号` | PLC knows current HMI page. | HMI writes current screen number to a register, useful for sequence/diagnostics. |
 | Function key/function area | Multi-action button behavior. | Use when a button needs several HMI actions, but keep PLC writes explicit and documented. |

 ## PLC-Controlled Screen Switching

 Recommended allocation:

 | Address | Direction | Purpose |
 |---|---|---|
 | `D100` | PLC -> HMI | Screen command register; value is target page number. |
 | `D101` | HMI -> PLC | Current screen report register. |
 | `M100` | HMI/PLC command | Request page change, edge driven. |
 | `M101` | PLC internal | One-shot or transition lock. |

 TouchWin steps:

 1. Open system settings for the HMI project.
 2. Enter the `交互` page.
 3. Enable `控制画面变换`.
 4. Set the object/register to the chosen PLC register, for example `D100`.
 5. Enable `报告当前画面号` and set a different register, for example `D101`.
 6. Download and test with offline/online simulation where available.

 PLC-side rule:

 - Write the target page number with an edge/event, not every scan.
 - Expect TouchWin to clear the screen command register to `0` after the jump.
 - Do not use the same register for command and current-screen report.

 Example ladder plan:

 | Network | Logic |
 |---|---|
 | Page request | HMI/PLC event sets `M100`. |
 | One-shot | `M100` rising edge writes `K10` to `D100` for page 10. |
 | Clear request | Reset `M100` after command or after `D101 = K10`. |
 | Timeout alarm | If `D101` does not become `K10` within a timeout, set an HMI communication/screen alarm bit. |

 ## Manual HMI Button Page Jump

 Use `部件 -> 操作键 -> 画面跳转` or the component toolbar:

 1. Place the `画面跳转` component.
 2. Set `跳转画面号`.
 3. Choose password mode if the page is maintenance/parameter/safety related.
 4. Use display/enable control when access depends on mode, alarm, or user permission.
 5. Name the button by destination: `主画面`, `参数`, `报警`, `手动`, `维护`.

 ## Button And Indicator Button Control

 | Component | Use | Caution |
 |---|---|---|
 | `按钮` | Write/toggle/set/reset a bit. | It does not display final bit state by itself. |
 | `指示灯按钮` | Operate one bit and display a bit state. | Operation object and monitor object can be separated; prefer separating command and status. |
 | `指示灯` | Display a bit/register state. | Use for actual PLC status, not command request alone. |

 Important rule from the TouchWin manual: when the HMI operates a lower-device bit, avoid using a direct PLC `OUT` instruction on the same bit. Use a command bit from HMI and a separate PLC-controlled status/output bit.

 ## Moving Object Animation

 Use either object X/Y animation or a `平移动画` component.

 ### Object X/Y movement by register

 Some objects expose animation settings:

 - `横向移动`: display X coordinate = original X + register value.
 - `纵向移动`: display Y coordinate = original Y + register value.

 Recommended for simple cart/tank/slider motion:

 | Address | Meaning |
 |---|---|
 | `D200` | X offset in pixels or engineering-scaled display units. |
 | `D201` | Y offset if needed. |
 | `M200` | Animation enable. |
 | `M201` | Reset animation position. |

 PLC pattern:

 1. Use a timer pulse to increment/decrement `D200`.
 2. Clamp `D200` between minimum and maximum display offsets.
 3. Reset `D200` to zero on homing/reset or page entry.
 4. Use separate real machine position when animation reflects actual equipment; do not let display animation become the control source.

 ### `平移动画`

 Use when the object should follow a drawn path.

 1. Place/draw the visible object or image.
 2. Add `平移动画`: `部件 -> 动画 -> 平移动画`.
 3. Draw the path; double-click to finish.
 4. Select the object and animation path, then group them.
 5. Configure duration/cycle time.
 6. Configure `许可信号`, `复位信号`, and `重复` as needed.

 ### `旋转动画`

 Use for fan/motor/agitator-style display:

 1. Add `旋转动画`.
 2. Add images/materials for the rotation frames.
 3. Set cycle time.
 4. Use a coil enable so the animation runs only when the corresponding PLC run status is ON.
 5. Use reset/visibility control for fault or stopped state.

 ## Cart Animation Template

 | PLC/HMI address | Purpose |
 |---|---|
 | `M300` | Cart run command. |
 | `M301` | Cart moving right status. |
 | `M302` | Cart moving left status. |
 | `M303` | Cart home sensor status. |
 | `M304` | Cart fault status. |
 | `D300` | Cart displayed X offset. |
 | `D301` | Cart actual position or simulated position. |

 HMI:

 - Bind the cart image horizontal animation to `D300`.
 - Display run/fault status with indicator lights.
 - Add manual jog buttons writing command bits, not direct output bits.

 PLC:

 - If real position is available, scale actual position into `D300`.
 - If only demonstration animation is needed, increment `D300` while moving and reset at ends.
 - Add limit checks; never use the HMI animation value as the only safety limit.

 ## Verification Checklist

 - Offline simulate screen jump buttons.
 - Online simulate PLC register-driven page jump if supported.
 - Confirm command register clears to `0` after page jump.
 - Confirm current-screen register updates correctly.
 - Confirm animation enable/reset bits work.
 - Confirm HMI command bits are not also driven by PLC `OUT`.
 - Download to HMI, verify PLC communication, then test alarms/permissions.

 # XDH-60T4 伺服与运动控制

 本参考仅针对 `XDH-60T4` 的 PLC 侧运动控制。先确认轴是接在本体晶体管脉冲口，还是接在 EtherCAT 总线上；两条路径的参数、接线、使能和诊断方式不同，不能混用。项目使用 `DS5C-20P4-PTA` 时，同时读取 `ds5c-20p4-pta-drive.md`；其他伺服驱动器仍必须以其型号手册为准。

 ## 已确认的机型能力

 | 项目 | 官方资料确认 | 工程含义 |
 |---|---|---|
 | 本体类型 | XDH-60T4 是 XDH-60 系列的 T4 型 | 使用晶体管输出，不是继电器脉冲输出。 |
 | 本地高速脉冲轴 | `Y0~Y3`，4 路 | 每一轴可作为脉冲输出端；方向端从其余晶体管输出中分配并在配置中明确指定。 |
 | 本地脉冲规格 | DC5~30V、最大 50mA、最大 100kHz | 驱动器脉冲输入必须与 OC 脉冲加方向方式兼容；不能只按“有脉冲口”判断兼容。 |
 | EtherCAT | XDH 有两个以太网口，EtherCAT 使用 `LAN2` | PLC 到第一个伺服 LAN1，再从该伺服的另一口串到下一台，采用线型拓扑。 |
 | 高级运动 | 高级运动篇适用于 XDH | 可用 EtherCAT 轴配置、轴调试、单轴/轴组/CAM/POU 功能；具体指令和版本条件逐项查原手册。 |

 来源：XDH-60 随机手册 PDF 1-2；定位控制篇 PDF 13-14；高级运动控制篇 PDF 8-10、42-45。

 ## 路径选择

 ### 本体脉冲加方向

 适用于驱动器提供脉冲输入，且项目需要 1-4 条独立本地轴的情形。

 1. 将轴脉冲输出分配到 `Y0~Y3`，每轴另外分配未被占用的晶体管输出作为方向端，避免多个轴复用同一方向端。
 2. 在 XDPPro 的脉冲参数/定位指令配置中设定脉冲端、方向端、方向极性、脉冲单位、每转脉冲数和机械单位换算。
 3. 在驱动器中把指令输入配置为与 PLC 相符的集电极开路、脉冲加方向、负逻辑输入形式；若驱动器仅接受差分输入，使用合适的 OC-Diff 转换方案并以驱动器接线图为准。
 4. 先做低速点动或小距离 `DRVI`，确认方向和实际位移；再做 `ZRN`，最后才允许绝对定位 `DRVA`。

 XDH-60T4 的脉冲输出属于 OC 脉冲加方向。定位控制篇指出定位用脉冲输出负载电流应为 DC5~24V、10~100mA；控制线应与动力线分开，并使用外部急停、正反转/上下限硬件互锁。不要从本体 I/O 名称推测具体伺服的 PUL/DIR 端子或 NPN/PNP 接法。

 来源：定位控制篇 PDF 13-14、162-168；XDH-60 随机手册 PDF 2。

 ### EtherCAT 总线轴

 适用于需要总线伺服、多轴同步、插补、电子凸轮、追剪或飞剪的项目。本地 4 路脉冲轴数不等于 EtherCAT 从站轴数，后者应以 PLC 型号配置、固件、驱动器和通讯周期实际核定。

 1. 在停机、断能状态完成 `LAN2 -> 第一台伺服 LAN1 -> 下一台伺服` 的线型接线，使用屏蔽工业以太网线并核对每个从站顺序。
 2. 在工程树的 PLC 配置中打开 EtherCAT；先扫描从站或手工添加匹配的 XML。`StationID 0` 是第一台从站，列表顺序必须与物理拓扑一致。
 3. 设定主站同步周期。高级运动篇给出的推荐值为：16 轴及以下 1000us，17-32 轴 2000us，33-64 轴 4000us；满足固件条件时，4 轴及以下可设 250us、8 轴及以下可设 500us。先以保守周期调通，再评估缩短周期。
 4. 将从站设置为 Servo Module，并把功能映射号与轴配置的从站号对应。不要把“站号”和程序使用的逻辑轴号混为一谈。
 5. 先配置并写入，随后激活。激活会让从站经历 `Init -> PreOP -> SafeOP -> OP`，其效果近似停机后重新运行，必须在设备可安全动作时执行。
 6. 在轴配置中选择 EtherCAT 指令通道，设置单位换算、电子齿轮/每圈脉冲数、正负限位、回原参数；轴调试前关闭程序里已有的轴使能。

 来源：高级运动控制篇 PDF 8-25、42-52。

 ## 脉冲定位指令路由

 | 目标 | 指令 | 必要认识 | 主要来源 |
 |---|---|---|---|
 | 相对移动 | `DRVI S0 S1 S2 D0 D1` | 上升/下降沿触发；`S0` 为脉冲数，负数反向；`S1` 为频率；`S2` 为 0 加速到设定频率的时间；`D0` 脉冲端、`D1` 方向端。 | 定位控制篇 PDF 111-116 |
 | 绝对移动 | `DRVA S0 S1 S2 D0 D1` | 目标以机械原点为基准，依赖累计脉冲位置；没有完成可靠回零前，不要把它作为真实机械绝对位置。 | 定位控制篇 PDF 117-122 |
 | 机械回零 | `ZRN S D` | 上升/下降沿触发；原点、极限、方向、爬行速度和可选 Z 相由参数配置。该指令不支持软限位和原点辅助信号功能。 | 定位控制篇 PDF 123-130 |
 | 发送过程判断 | `SM1000` / `SM1020` / `SM1040` / `SM1060` | 分别对应 Y0/Y1/Y2/Y3 正在发脉冲。其下降沿表示 PLC 已发完脉冲，不等于机械已真正停止到位。 | 定位控制篇 PDF 169-170 |

 同一脉冲端口在脉冲发送期间，新的定位指令不会被响应。为每轴建立独立的“请求、忙、完成、故障、到位”状态机，完成条件至少组合 PLC 脉冲发送结束、驱动器报警正常、驱动器到位或机械反馈条件，不能只靠 `SM1000` 的下降沿。

 ## EtherCAT 单轴和 POU 路由

 高级运动篇的原梯形图单轴指令包括 `A_PWR`（使能）、`A_RST`（清错）、`A_STOP`（停止）、`A_HALT`（暂停）、`A_MOVEA`（绝对位置）、`A_MOVER`（相对位置）、`A_VELMOVE`（速度）和 `A_HOME`（HM 回原）。它们与脉冲 `DRVI`/`DRVA`/`ZRN` 是两套不同控制层，不要对同一个轴同时交叉下令。

 需要 POU 时，XDPPro 可在运动 POU 库中使用带 `BMC_` 前缀的指令，例如 `BMC_A_POWER`。轴配置添加轴后会生成轴结构体变量；使用前在系统变量表中勾选“引用”。POU 引脚必须关联类型匹配的变量，不能直接把寄存器或线圈接到 POU 引脚。

 来源：高级运动控制篇 PDF 64-75。

 ## 调试与诊断顺序

 1. 备份工程、核对急停/防护门/STO、外部正负限位、机械区域清空；先停止主运动并解除负载风险。
 2. 先监控，不先强制输出。脉冲轴核查 `Y0~Y3` LED、方向输出、累计脉冲寄存器和对应发送标志；总线轴核查从站状态、故障和轴反馈。
 3. 脉冲轴不动作时依次核查接线、PLC 端 LED/方向、累计脉冲是否变化、驱动器输入形式是否匹配。停止位置不准时优先核查电子齿轮、原点/爬行速度、编码器 Z 相和机械背隙。
 4. EtherCAT 轴先确认实际从站顺序、StationID、功能映射号、PDO 映射和是否到 OP；状态可从 `SD[8021+20*i]` 观察，状态切换错误可从 `SD[8028+20*i]` 查阅。
 5. 仅在确知对象、停机状态和恢复方案时修改 CoE-Online、SDO 或 ESC 寄存器。部分对象或寄存器的在线写入会造成通讯中断。

 ## 版本与未决信息

 - 定位控制篇列出 XDH 需要 XDPPro V3.7.4 及以上；高级运动中的具体功能还会各自要求固件和软件版本，实施前逐条核对。
 - `XDH-60T4` 已能确认本地 4 路脉冲输出；EtherCAT 的实际可用从站数、周期和控制模式应以当前 PLC 固件、驱动器 XML、驱动器型号和工程配置为准。
 - 当前 DS5C-20P4-PTA 的驱动器侧资料见 `ds5c-20p4-pta-drive.md`。获得电机完整型号、机械传动数据、限位/原点传感器和当前 XDPPro 版本后，可继续生成这套设备的接线表、参数表、软元件分配和梯形图/POU 顺序。
