Custom Web Control
About Process Trend Monitor
The Process Trend Monitor is a high-performance Custom Web Control designed for advanced industrial SCADA and HMI environments. It provides a sophisticated multi-channel trend viewer for monitoring real-time and historical process data with precision. This control is engineered for seamless integration into WinCC Unified (TIA Portal) and WinCC V8, allowing engineers to visualize complex data streams without custom coding.
Key Features
- Dynamic Data Visualization: Manage multiple signals simultaneously using the lines property, which supports both live PLC tags and file-based historical data.
- Flexible Scaling: Utilize the autoScaleY boolean for automatic range calculation or define precise boundaries using yAxisMin and yAxisMax.
- Data Portability: Features a built-in CSV export function triggered by the exportButtonText, allowing operators to extract data for external analysis.
- Interactive Interface: Includes a collapsible sidebar for streamlined navigation, controlled via the sidebarToggleText and the toggleSidebar method.
Customization
The control offers 11 configurable properties to match your corporate identity and operational needs. Adjust the backgroundColor for dark-mode compatibility, toggle visual aids like showLimits and showGrid, and define the rolling observation window using timeRangeSeconds. The titleText property ensures clear identification of the monitored process on any dashboard.
Use Cases
This monitor is ideal for continuous process industries, such as water treatment, chemical manufacturing, and energy management, where tracking variable fluctuations over time is critical for operational safety and efficiency.
Compatibility
Fully compatible with WinCC Unified (TIA Portal) and WinCC V8. The control supports event-driven logic through the PointAdded and ExportTriggered events, and provides programmatic control via the clearBuffers method.
💡 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.
