OmronEthernetFINSCom error EIPTransport.SendData-No Response
« on: September 14, 2019, 06:39:33 AM »
Hello,
Sorry for my English, it is translated by google translator.
I am trying to connect to an Omron cj2m (UDP) PLC but I also perform tests with a simulator on the PC (the same applies to both the simulator and the PLC). The problem is that the driver responds to me with the error EIPTransport.SendData-No Response (-123). Looking at the packages in the Wireshark seems all right, I have only managed to work from a virtual machine with Windows 7 but I do not find it special for it to work. I add packet capture.

I see in the Wireshark capture the UDP packet is sent to port 9600, but a response is returned from port 3712

You are right, that was the problem, the FINS protocol simulator that I am using creates a new connection to answer, I have changed it and it already works. Thank you very much for your help.
