I am having a problem on S7/Profibus. There are a number of identical ET200 RIO nodes. While the equipment was down between orders a fault appeared for loss of one of the nodes on inspection the BF light was flashing. Cable and hardware were verified, then the address was swapped with another identical node. The problem followed the address. In HW Config this address shows a red slash through it. I typically work on AB products so I have limited experience with S7/Proifbus but do have access to the SW and I am familiar enough to poke around. Any suggestions would be helpful.
