Hi @wihl,
So valid position for cf is 10 o’clock? or 9 o’clock?
There are two valid positions for the memory selection switch. They look to be 10 o’clock and 12 o’clock from the above picture. No other selections are possible or valid.
This thread is getting a little confusing to follow. It sounds like maybe the selection switch isn’t working correctly on your PLC. I recommend you get in touch with your local B&R support team so that someone can work with you directly. Wenbo and Michael have provided you with a lot of guidance, but I think this is getting beyond what the Community is able to help with.
