SCADA Quick Start
1. Purpose
This page guides users through creating a Web SCADA page, binding device thing-model variables, and verifying real-time display and control.
2. Build Flow
3. Prerequisites
| Condition | Description |
|---|---|
| Product exists | Template SCADA pages usually need a product. |
| Thing model is stable | Variable binding depends on thing-model identifiers. |
| Device has data | Preview can show real values only when data is reported. |
| Assets are ready | Background images, device icons, and process diagrams are prepared. |
| Permission is granted | The user has SCADA management and design permission. |
4. Create A SCADA Page
Path:
SCADA Management > Template / Scene / Independent SCADA > AddSCADA center example:
| Type | Scenario |
|---|---|
| Template SCADA | Multiple devices under the same product share one page. |
| Scene SCADA | Variables from scenes or multiple devices. |
| Independent SCADA | Standalone display page or big screen. |
5. Design The Page
Designer example:
Recommended order:
- Set canvas size and background.
- Add title, regions, and static shapes.
- Add data display components.
- Add status and control components.
- Bind thing-model variables.
- Configure click events or linkage.
- Preview and adjust layout.
6. Variable Binding
| Check Item | Description |
|---|---|
| Variable source | Product, device, scene, or public API. |
| Identifier | Must match the thing-model id. |
| Data type | Boolean, enum, number, array, or object. |
| Refresh mode | Realtime, scheduled, or manual refresh. |
| Default value | Display value when the device is offline or no data exists. |
7. Preview And Publish
Before publishing, verify layout, variable values, offline default state, click events, command delivery, and share-link permission.
Common Problems
| Problem | Check |
|---|---|
| Variable has no value | Device online status, identifier, data reporting, and variable source. |
| Preview scaling is abnormal | Canvas size, browser zoom, locked components, and mobile adaptation. |
| Share link cannot open | Share status, password, deleted page, and public domain access. |
| Control button fails | Writable thing model, device online status, command topic, and device-side handling. |
