Custom Web Control
About Status Bar
The Status Bar is a high-performance Custom Web Control designed for WinCC Unified and WinCC V8 environments. It provides a dynamic, horizontal timeline visualization that tracks and displays the historical duration of process states in real-time. By transforming raw state data into a continuous visual stream, it allows operators to instantly grasp machine performance and downtime patterns at a glance.
Key Features
- Dynamic State Tracking: Automatically generates new timeline segments whenever the status property changes, supporting distinct colors for Green, Red, Gray, and Yellow states.
- Historical Data Management: Maintain a rolling window of process history by defining the maxHistoryMinutes, ensuring the interface remains clean and relevant.
- Interactive Tooltips: When showTooltips is enabled, operators can hover over any segment to view precise start times, end times, and total durations for specific events.
- Advanced Methods: Includes resetHistory for clearing the timeline and exportHistoryJson for extracting historical data for external reporting or logging.
Customization
The control offers 13 configurable properties to match your corporate identity and operational needs. You can adjust the barHeight and borderRadius for a modern look, set custom labels via state1Label through unknownStateLabel, and modify the backgroundColor to fit your HMI theme. The updateInterval ensures the current active segment expands smoothly in real-time.
Use Cases
Perfect for monitoring production line availability (OEE), tracking motor operational states, visualizing alarm durations, and identifying intermittent faults in automated machinery.
Compatibility
Fully compatible with WinCC Unified (TIA Portal) and WinCC V8. The control supports bidirectional communication through the OnStatusChanged and OnHistoryCleared events.
💡 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.
