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.
