Chapter 9 Use I/O Modules with CompactLogix 5370 L3 Controllers
Distributed I/O Modules over an EtherNet/IP Network
You can include distributed I/O modules over an EtherNet/IP network in your
CompactLogix 5370 control system. Consider the following when using
distributed I/O modules over an EtherNet/IP network:
• Each remote EtherNet/IP adapter included in the system must be counted
toward the maximum number of EtherNet/IP nodes for the controller.
For more information on maximum number of EtherNet/IP nodes, see
Nodes on an EtherNet/IP Network
on page 125.
• The configurable RPI settings vary depending on which distributed I/O
modules are used in the system.
• For information to add distributed I/O modules to your CompactLogix
5370 control system, see Configure Distributed I/O Modules on a
DeviceNet Network on page 258.
The following graphic shows an example 1769-L33ERM control system that uses
local expansion modules and distributed I/O modules over an EtherNet/IP
network.
