Now I have a system using Rockwell ControlLogix as controller, and there are some Profibus PA meters need to be connected to the ControlLogix. So I used a SST module located in ControlLogix chasis to connect Profibus DP then DP/PA link to meters. But the communication can not be set up.

Does anybody have this kind of experience? Or any suggestion for trouble shooting?

Thanks!

Niu,

I have done it and it works fine. What is the nature of the problem and maybe I can help. I have a sample program and some documentation that I created myself.

As an added feature for this setup we use the Siemens IE(Ethernet)/PB (Profibus) Link after the Control Logix to access the Instrumentation over Ethernet using Siemens PDM software.

John,

My SST Module is SST-PFB-CLX, firmware V4.07. DP/PA link is 6ES7 157-0AA82-0XA0, firmware V4.0.4. DP/PA Coupler is 6ES7 157-0AC81-0XA0, PA Device is E+H PDM235.

Now, I can't Configure PA with SST Profibus Configuration tool. The DP segment is OK, but PA segment is not OK!

If I Move the DP master to S7-400, all OK!

Please send me you sample configure or docmentation, give me some help.

thanks
