Hi,I want to make a profibus connection between CPU 315-2DP and a Emerson Delta V controller and read data from S7 system. I installed a Profibus DP card to emerson system and it is master as default ithink. So CPU 315 must be slave i think. I installed gsd file of CPU315 to emerson system. But I couldn't establish the connection. Can anyone tell me how to make the connection? I made the adjustments on emerson, like gsd file, creating device, port, channel, baud-rate etc. But I dont know what to make on siemens side. Is there anything to do on siemens side?
