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 ?

 

You might want to check how this port (18246) is represented in the Siemens and GE Side. I think GE is an intel processor and hence little-endian. If the other side is different, you need to do a byte order conversion to get the data through.

Could be a possibility? Not sure.

Are you using unicast or multicast? are you using an address such as 224.x.x.x or something like 192.168.2.3? I'd be very surprised if the Siemens would receive multicast in a "free protocol" manner.
