Nodes on an EtherNet/IP Network
When configuring your CompactLogix 5370 control system, you must
account for the number of Ethernet nodes you include in the I/O
configuration section of your project. CompactLogix 5370 controllers have
limits on the number of nodes they support in the I/O configuration section.
