Function in UniLogic Ladder module went blank

Recommended Posts

is there any way to debug this? On the picture there is function, which went blank. But actually there are rungs with Call Func" commands for another functions in the program. The  "Call Func" logic in the program loaded into PLC works, but the function in program is blank, and cannot be deleted or written into.

You have triangles near the region name and comment that suggests if its expanded or collapsed.
