Custom Web Control
About Heatmap
The Heatmap is a high-performance Custom Web Control (CWC) specifically engineered for industrial SCADA and HMI environments. It provides a dynamic, grid-based visualization for analyzing data density and production loads across complex categories. By integrating this control into WinCC Unified (TIA Portal) or WinCC V8, engineers can transform raw process data into intuitive, color-coded insights that enhance situational awareness and decision-making speed.
Key Features
- Dynamic Scaling: Automatically maps numeric values to a high-contrast color gradient defined by the startColor and endColor properties.
- Interactive Selection: The CellClicked event allows operators to trigger specific HMI actions or drill-down views by interacting directly with grid elements.
- Real-Time Labeling: Toggle the showValueLabels property to display precise data points directly within cells for immediate technical verification.
- Flexible Data Handling: Supports both JSON arrays and comma-separated strings for axis labeling via xAxisLabels and yAxisLabels.
Customization
The Heatmap offers 11 bindable properties for seamless integration into your project. Users can define visual boundaries using minValue and maxValue to ensure the gradient accurately reflects process extremes. The unitLabel property ensures tooltips provide context-aware information, while the backgroundColor can be adjusted to match industrial dark mode standards. Developers can also utilize the refreshChart and clearData methods for programmatic runtime control.
Use Cases
This control is ideal for monitoring thermal distribution in industrial kilns, analyzing machine utilization across multiple production lines, or visualizing energy consumption patterns. It is particularly effective for identifying operational bottlenecks and load imbalances in real-time dashboards.
Compatibility
Fully compatible with WinCC Unified (TIA Portal) and WinCC V8. This control is designed for low-latency updates and high reliability in demanding industrial environments.
