CMX 40 - Redundancy switch-over with programs running in test RAM
- In the case of larger changes in the program structure, the new program should not be operated in the test RAM.
If a program is running in the test RAM, the redundancy switch-over is not locked for availability reasons. If a switch-over takes place now, the EEPROM program runs in the CMX becoming active.
In the case of extensive changes in the program (e. g. new steps in the GCM etc.), the old program structure becomes active again.
