This article discusses how Modicon M580 EPAC can communicate with devices using IO Scanning at different network domains.
M580 can have IO Scanning devices at different domains which can be configured under ENOC

Example: Communicating devices on "A.B.C.D" network, while the ENOC is on "W.X.Y.Z" network.

This can be implemented either by inserting a router in between NOC03x1.3 and the communicating device, or by using ENOC0321 which has the feature of IP forwarding.
