Chapter 1 Redundancy System Overview
System Context
The redundant I/O subsystem must be connected to one ControlLogix
redundancy system, or any Logix system that supports I/O via the
EtherNet/IP™ network. The topologies that the 1756-EN2T or 1756-EN2TR
modules support, DLR (Ring) or Star, establish all connections via the Ethernet
network.
For more information about DLR topologies, see the EtherNet/IP Embedded
Switch Technology Application Guide, publication ENET-AP005
.
