Use P_ON and P_OFF in Omron PLC Programming

How to Use P_on and P_off on Omron PLC :-


In our earlier tutorial we have already understoof about the the PLC Internal Memory System Bits. When we make the PLC Program at a earlier stage of development than we have to include all the function and logic in it . But at the later stage we have to cut something out of it or add new logic and program sections.
Suppose that if we want that a particular rung condition should always be true , thus in this case we can use P_ON system flag.
Also while troubleshooting the PLC program if we want to cut the on condition of certain rung than we can use P_off.
