Custom Web Control
About Trend Chart
Trend Chart is a high-performance Custom Web Control powered by the ECharts engine, specifically engineered for WinCC Unified and WinCC V8 environments. It provides high-fidelity, real-time visualization of process variables over time, allowing operators to track trends and fluctuations with precision. This control transforms raw data into actionable insights, ensuring that critical process changes are never missed.
Key Features
- Dynamic Data Visualization: Render multiple data streams simultaneously using the lines property, supporting custom colors and data configurations.
- Intelligent Scaling: Utilize autoScaleY for dynamic range adjustment or maintain strict control with fixed boundaries via yAxisMin and yAxisMax.
- Proactive Monitoring: The built-in LimitExceeded event triggers when process values cross predefined thresholds, while showLimits provides a clear visual setpoint overlay.
- Interactive Analytics: The PointClicked event enables deep-dive data inspection, allowing operators to interact directly with specific data points on the timeline.
Customization
The control offers extensive styling and behavior options. Developers can configure the backgroundColor and showGrid settings to match corporate design standards. The timeRangeSeconds property allows for precise management of the sliding time window, while the chartTitle ensures clear identification of the process being monitored.
Use Cases
Ideal for monitoring temperature profiles, pressure fluctuations, flow rates, and energy consumption across manufacturing, water treatment, and chemical processing plants.
Compatibility
Works with WinCC Unified (TIA Portal) and WinCC V8. Includes full support for property binding and event handling within the WinCC engineering environment.
💡 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.
