While PLC runs debugging, just one condition if only satisfied among breakpoint, device break, scan
break, etc., will apply the break.
-
Click the left mouse button on the program name to move to the program position where the device
break is applied.
-
If the value is changed in other application programs (such as device monitor) than the specified device
program, movement to the program position where the device break is applied may not be possible.
