Posted 14 Aug 2023 (edited) You could try using the BACKUP/RESTORE procedure using a CF card. BACKUP exiting PLC program to CF Card. RESTORE program to other PLC using CF Card. Depending on how the program was originally protected this should work. BUT if the other PLC is a different Version # this may cause a problem.
