Custom Web Control
About Pie Chart
The Pie Chart is a high-performance Custom Web Control (CWC) engineered specifically for industrial SCADA and HMI environments. It provides a dynamic solution for visualizing process data distribution, allowing operators to see proportional relationships between variables at a glance. Simply import this control into your WinCC Unified (TIA Portal) or WinCC V8 project to enhance your dashboards with professional-grade data visualization that bridges the gap between raw data and actionable insights.
Key Features
- Interactive Visualization: Features high-fidelity rendering with interactive tooltips that display values alongside your specified unit of measurement for precise inspection.
- Donut Mode Support: Seamlessly switch between a standard pie chart and a modern donut chart by adjusting the innerRadius and outerRadius percentage properties.
- Event-Driven Logic: Utilize the SliceClicked event to trigger specific HMI actions, script execution, or screen navigation when a user interacts with a chart segment.
- Runtime Control: Includes the refresh method for instant UI updates and resetValues for clearing data during batch transitions or system initializations.
Customization
This control offers 8 configurable properties for deep HMI integration. Developers can define the title, toggle the showLegend flag, and specify the legendPosition (top, bottom, left, or right) to optimize screen real estate. The slices array supports dynamic data binding directly from PLC tags, while the backgroundColor property ensures the control fits perfectly within your existing industrial theme.
Use Cases
- Energy Management: Visualizing power consumption distribution across different production lines or departments.
- Process Composition: Displaying the percentage of ingredients or chemical components in a mixing vessel.
- OEE Dashboards: Viewing the distribution of equipment states such as Running, Idle, and Fault durations.
Compatibility
Fully compatible with WinCC Unified (TIA Portal) and WinCC V8. The package includes comprehensive documentation to assist with installation and tag binding.
💡 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.
