I have configured GE Fanuc Versamax CPUE005 for EGD telegrams to be sent & received with Siemens' S7-400. However the communication doesn't succeed. Both the ends send the telegram successfully but none of them is able to receive. The GEF PLC transmits this data on a default port 18246(dec). Is there any restrictions on the Siemens side on this port number ? I am familiar to EGD configuration at GEF end and have suceede in communicating amongst GEF CPUs. Can somebody please help me on this ?
