SCADA Events And Scripts

1. Event Types

Event	Usage
Click	Open dialog, switch page, deliver command, or run script.
Value change	Trigger style changes or linkage when a variable changes.
Timer	Periodically refresh data or run a script.
Page load	Initialize variables, load data, or set default state.

2. Common Interaction Flow

3. Script Usage

Scripts are suitable for value formatting, simple conditional display, and lightweight linkage. Keep scripts short and deterministic. Complex business logic should be implemented in backend rules or services.

Scenario	Recommendation
Format value	Convert raw number into display text or color.
Show or hide	Control component visibility by variable value.
Simple linkage	Change style or open a panel when a condition is met.
Command preparation	Assemble command parameters before delivery.

4. Safety Notes

• Add confirmation for commands that affect real devices.
• Do not expose sensitive tokens or private API addresses in page scripts.
• Test scripts with missing, null, and abnormal values.
• Keep permission validation on the backend as well as the frontend.
