Note The maximum current consumption of the CS1W-EIP21 and CJ1W-EIP21
EtherNet/IP Units is 410 mA. Be sure that the total current consumption of all
the Units connected to the same CPU Backplane or Expansion Backplane
does not exceed the output capacity of the Power Supply Unit.
The following table shows the devices recommended for use with the Ether-
Net/IP Unit 2-3 Selecting the Network Devices.

due to tag data links, we recommend configuring the network so that the
load does not affect communications. For example, install the tag data
links in a segment that is separate from the information network.
