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.
