Hi,
I am using 800xA with SV5.1 RevA.
I have redundant network for profibus. Need to communicate with siemens S7 PLC via DP/DP coupler.
With one DP/DP coupler I already did the communication and is working fine. I have redundant DP/DP coupler
for the same signals. How can I do this..... Any options to enable redundant mode in DP/DP coupler?

Is Profibus in Siemens-side redundant? If not you are probably need allocate a redundancy link module (such as ABB RLM01) between DP-DP coupler and 2 redundant Profibuses of AC 800M.

Otherwise I don't understand what's a problem to couple line A to the 1st coupler, line B - to the 2nd ?
