3-4-11 DeviceNet I/O Link Unit Connections
A DeviceNet I/O Link Unit can be used to create an I/O link (remote I/O) of 32
input points and 32 output points with a DeviceNet master, i.e., the CPM1A oper-
ates as a DeviceNet slave.
Up to three DeviceNet I/O Link Units can be connected, for a maximum Device-
Net I/O link capacity of 192 I/O points (96 inputs and 96 outputs). The DeviceNet
I/O Link Unit can be connected only to 30-point or 40-point CPU Units.

Remote I/O communications are
possible as a DeviceNet slave
for up to 32 input and 32 output
points for each Unit.
Note The current consumption for communications for the DeviceNet I/O Link Unit is
30 mA.
