About Line State Gantt
Line State Gantt is a Custom Web Control that visualizes production line states as a Gantt-style timeline across an 8-hour shift window. A summary lane gives an overview of the whole window, while optional per-state lanes show exactly when each state occurred. Stops are listed below the chart with start time, duration, state and reason, so operators and supervisors can move from the big picture to the detail in one view.
Key Features
- Summary and state lanes: Displays an overview lane, plus one lane per state when lane breakdown is enabled.
- Stop list: Lists each stop with start time, duration, state and reason. Hovering or clicking a row highlights the matching segment in the chart, and the reverse also applies.
- Zoom and pan: Inspect short events or review the full shift without leaving the screen.
- Segment selection: The SegmentSelected event fires when a segment or stop row is selected, so the project can react, for example by opening a detail view.
- Follow-now mode: When enabled, the window ends at the current time and refreshes every 30 seconds.
Customization
All behavior is controlled by 10 properties defined in the interface contract and bound to HMI tags or set in the engineering tool. segments carries the state history with start and end times, where an empty end marks an ongoing state. states defines lane names, colors, patterns and which states appear in the stop list. timeWindowHours sets the visible window length, and endTime selects a previous shift for review when follow-now mode is off. minStopDurationSec filters short stops from the list. showStopList and showLaneBreakdown control the layout, timeFormat24h switches the axis and list between 24-hour and 12-hour AM/PM time, and backgroundColor sets the base color.
Use Cases
Suited for production line overview screens, shift handover displays, loss analysis at the operator panel, and supervisor review of previous shifts.
Compatibility
Runs in WinCC Unified (TIA Portal) and WinCC V8. Import the control into your project and bind its properties to PLC tags.
