The changes are written to the PLC.
Writing Changes to a Target PLC
If you change the size of the program, you must write the changes to the PLC to
maintain equality. You can do so whether the target is running or not. All PLC
families support this run-mode store capability, but not every PLC in every family.
To write changes to the target PLC
1. While online to a target, make a change to LD logic.
2. In the Project tab of the Navigator, right-click the target, point to Online Commands, and choose
Write Changes.
New logic is immediately written to the PLC without stopping the PLC. If the LD
logic was altered, other than a word-for-word change, you are prompted to
download to the running PLC. The entire target is validated, but only the changed
blocks are downloaded.
To turn on/off or force a variable
In the LD editor, right-click a BOOL variable anywhere in LD logic and choose Force ON, Force OFF, Turn ON, or
Turn OFF.
Note: Forcing a variable ON or OFF overrides any actions the application may
take during runtime. That is, if a variable is forced OFF (0), but LD logic is trying to
turn it ON (1), it stays OFF.
