AC450 & S7-300 interface
As title, I am trying to make profibus DP connection between ABB AC450 and Siemens S7-300 PLC, but I have could not make it.
Seems I have been missing something.
My question is that
1. Is it possible to make profibus DP connection between them?
2. If so, what should I check?
Best regards, JS Choi

The AC450 Profibus interface can be unreliable. You should carefully consider the impact on the process if the interface fails.
