When making modifications to a PLC program, it is important to ensure your changes are synchronized between the online monitor and the PLC. This process involves going online to access the most up-to-date file, making the necessary modifications offline, and then pressing the online change button. If any changes are made to the block header, you can only compile and download the program by halting the PLC.

I would suggest leveraging the "Online Edit" feature in GX Works 2. This will allow you to implement changes to a running PLC program without causing any interruption to its operation. However, you must be careful and thoroughly test each change in a controlled setup before implementing it on the running system, to avoid any unforeseen issues. Also, make sure to backup your current program before making changes, so you have the ability to revert if something unexpected occurs.
