Design an Enhanced Redundancy System Chapter 2
EtherNet/IP Networks with
Redundant Systems
The use of EtherNet/IP networks in an enhanced redundancy system is primarily
dependent on your system revision.
For more information on using an EtherNet/IP network in your enhanced
redundancy system, see Chapter 5
, Configure the ControlNet Network on
page 93.
EtherNet/IP Network Features in an Enhanced Redundancy System,
Revision 19.052 or Later
In an enhanced redundancy system, revision 19.052 or later, you can execute
these tasks on an EtherNet/IP network:
• Use 1756-EN2TR modules
• Connect to remote I/O modules
• Connect to 1715 Redundant I/O systems
• Use produce/consume tags
• Connect to a Device-level Ring networks
• Use CIP Sync technology
The rest of the topics in this section apply to all enhanced redundancy systems.
A remote chassis can be accessed over an EtherNet/IP network using any
EtherNet/IP module that works in a nonredundant chassis with no additional
firmware requirement with the following exception. If the remote chassis
contains a controller consuming a tag produced in the RCP, it can only consume
the tag with the required firmware revisions listed in Tabl e 7
.
