I have this problem with an S7-413-2 CPU.
The MPI adress of port X1 is set to 3. I want to change it to 2.
But no matter what I do, it stubbornly refuses to do my bidding .
I try to change the MPI adress in Step7 hardware config and then download it - no change.
I try to do an online CPU reset - no change.
I try to power down, remove the battery and the memory card, power up - no change.
I try to do a CPU reset with the keyswitch - no change.
Step7 "available nodes" tell me that the CPU is constantly MPI adress no. 3. Is this adress chiselled into the silicon or what ?
Please - ANY ideas or suggestions ?
