Answer
<Cause>
When a control device memory bit is used to display a normal overlap or call-overlap part, only the leading edge (OFF -> ON) is recognized.
If the screen is moved back while the bit remains ON, the overlap part will not be displayed.
<Solutions>
The following three methods are available.
- To display the overlap part whenever the bit is ON, select [System Setting] → [Unit Setting] → [General Settings] and check [Display Overlap during bit ON].
- Use a multi-overlap part and call it using a control device memory bit.
- Use a global overlap part.
