Using Multihop Messaging

You can use multihop messaging over Ethernet, so that controllers can
communicate over Ethernet with ControlLogix devices or through a
ControlLogix Ethernet module (1756-ENET) to other PLC-5 and SLC
controllers. You need a series E, revision D or later PLC-5 controller, and if
using a sidecar module, you will need a series B or later 1785-ENET interface
module.

To take advantage of these enhancements, you need RSLogix 5 programming
software, release 3.2 or later.
