My customer has 2 identical machines with Siemens S7-315-2dp controllers. Each controller talks to 2 remote racks over ProfiBus. I want to add a WAGO 750-8206 as a slave to the ProfiBus network.
Before I went to the field I set up an S7-315-2dp to talk with the WAGO. On my desk we were able to get the whole thing going in about 10 minutes.
Out in the field things didn't go so well. My colleague spent a whole day on this and couldn't get it to work. The ProfiBus network LEDs are all green. Disconnecting the WAGO causes a fault. Reconnecting the controller clears the fault. The only thing is that data doesn't transfer.
I took a look at this today and wasted an additional 2 hours getting nothing to work. Everything indicates that communications should be working but they're not.
What am I missing?
Thanks,
Yosi
