Ok I have never set up communications between two PLCs both machines are using 192.168.1.1 for the PLC. I need to setup produce consume tags between the two machines. For part transfers. The guard logix is a 1756-L72S 5570 safety controller and the compact logix is a 1769-L33ER compact logix 5370 controller the only Ethernet I have available is one port open to the Guard Logix Stratix 5700 switch on the same network as the controller and on on the compact logix one port on a 1783 NATR and suggestions would be greatly appreciated!
