I am having a problem when trying to connect to a product we designed that uses the Ethernet/IP protocol. I used one of the implicit messaging examples and was able to establish a connection. Only problem was that after 10 seconds, the device times out and closes the TCP connection. I believe that when the Forward open Command is issued, we respond with a success, along with a connection ID.
Unfortunately, the Master does not use this connection ID to when sending O->T messages, so our device ignores these.
I was wondering if this was an issue for anybody else?

Do you have any examples controling 1756 ControlLogix I/O. Say 1756-IA32 Input Card, 1756-OW16I Isolated Output Card and 1756-IF16 Analog Input Card in a rack with 1756-EN2T Ethernet Card?
