EtherNet/IP Module Checklist
ControlNet HMI
A ControlNet network or a ControlNet-to-EtherNet/IP gateway is used to connect to HMI because your system requires that HMI be updated immediately after a
switchover.
• PanelView Standard terminal, PanelView 1000e or 1400e terminal
For an unscheduled network, 

4 HMI terminals per controller are used.
For a scheduled network, any amount of terminals within the limits of the ControlNet network are used.
• PanelView Plus terminal, VersaView industrial computer running a Windows CE operating system
RSLinx Enterprise software, version 5.0 or later, is used.
Within each controller and communication module, five connections for each PanelView Plus or VersaView terminal are reserved.
• FactoryTalk View SE software with RSLinx communication software, version 2.52 or later, RSView® 32 software, RSLinx Enterprise software, version 5.0
The number of RSLinx servers that a controller uses is limited to 1…4 (maximum).
(1) Unscheduled ControlNet networks can be used, however, certain use considerations must be made. See Chapter 5, Configure the ControlNet Network on page 93 .

EtherNet/IP Module
Identical EtherNet/IP communication modules are placed in the same slot of both chassis of the redundant chassis pair.
EtherNet/IP communication modules are one of these catalog numbers:
• 1756-EN2T, 1756-EN2TXT, 1756-EN2TR, 1756-EN2F
EtherNet/IP Network
With firmware revision 19.052 and later, you can use an EtherNet/IP network for I/O and produced/consumed tags.
With firmware revisions 16.081 and earlier, an EtherNet/IP network does not support I/O or produced/consumed tags.
Enhanced redundancy systems support unicast produced tags. Unicast consumed tags are not supported in enhanced redundancy systems.
USB ports of communication modules in the redundant chassis are not used while the system is running (online).
IP addresses of devices on the EtherNet/IP network are static and IP address swapping is enabled. (1)
