Custom Web Control
About Status LED
The Status LED is a high-performance Custom Web Control designed for WinCC Unified and WinCC V8 environments. It provides a circular, high-visibility status indicator that delivers immediate visual feedback for critical process conditions. By utilizing advanced CSS animations and SVG rendering, it ensures that machine states are clearly communicated to operators through color-coded signals and dynamic glow effects.
Key Features
- Dynamic State Management: Use the isActive property to toggle between Active and Inactive states with zero latency.
- Visual Pulsing: Enhance situational awareness by enabling the glowEnabled feature, which adds a rhythmic pulse to the indicator.
- Integrated Labeling: Display context-specific text using the activeLabel and inactiveLabel properties to eliminate ambiguity.
- Interactive Methods: Programmatically control the UI using the toggleState and setState methods for advanced automation logic.
Customization
Engineers can fully tailor the visual identity of the control to match corporate standards or specific safety requirements. Adjust the borderThickness for a bolder look, modify the backgroundColor of the container, and fine-tune the glowIntensity to ensure the indicator is visible even in high-glare control room environments.
Use Cases
This control is ideal for monitoring motor run status, valve positions, safety interlocks, and alarm conditions. It is perfectly suited for high-density overview screens where clear, non-textual status representation is required for rapid decision-making.
Compatibility
Fully compatible with WinCC Unified (TIA Portal) and WinCC V8. The control supports seamless tag binding for all 7 properties and triggers the StateChanged event for logging or secondary logic execution.
💡 TIA Portal Reminder: Remember to uncheck the "Read only" option in TIA Portal when linking a tag to a property that needs to be written from the Custom Web Control. If you do not, the CWC will only be able to read the HMI tags and not write to them.
