Machinelogic - How Do I Clear Retentive Memory?
Retentive memory will be cleared on a cold start. A cold start will occur any time you change the program, recompile and send it down. The cold start will only work if the program date does not change from the time you stop the program to the time you want to restart it. The work around could be a patch the POU. The larger sized RTXDOS should give you the room you need in order to allow patches without a problem.
