I have a Compact logix L35E and a remote B&R X20B I/O system on a plant network that was working until we had to change the IP addressing because of updates to our network systems. Since the change i get an IO not responding fault on the L35E. I can ping the B&R from the L35E network line. The subnets are the same (255.255.255.0) however the devices are now on different gateways.
L35E IP 10.7.111.51 subent 255.255.255.0 gateway 10.7.111.10
B&R IP 10.7.121.125 subnet 255.255.255.0 gateway 10.7.121.10
Not sure this is why we get the fault.Thanks for any advice on this.
 
Is that connection setup as Multicast or Unicast?

Multicast connections will not route across gateways w/out further configuration on the Network end.
