Hi all,
I need some help with S5 system. I have a working CPU 928B (6ES5928-3UB21) with flash memory submodule (6ES5 374-2KG21). I need to make small modification in program. The problem appears when i try to download modified FB to PLC. In STEP5 red message appears "Block exists in PLC" and block is not transferred. I tried to remove flash memory, reset PLC but no success.
Maybe somebody can suggest how to download modified block to PLC.
By the way-on other machine running exactly the same system (even without flash memory) but no such problems with transfer apears.
Thanks for prompt replay.
