The data for a trend part ([Display Mode: Real Time Display]) differs from the latest data in the PLC.
<Cause>
The trend graph is not redrawn.
<Solution>
The graph data once displayed is not updated unless the redraw command is specified.
To update to the latest data, set bit 14 or 15 of the control device memory (OFF to ON for leading edge).

- Bit 14
Trend lines are redrawn at the leading edge (0 -> 1) by the specified number of points. Drawing is performed over the previous one without clearing the trend graph area. - Bit 15
Trend lines are redrawn at the leading edge (0 -> 1) by the specified number of points. The trend graph area is cleared and the newest trend lines are drawn.
