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. From the standpoint of the CPM1A CPU Unit, the
area allocated to the DeviceNet I/O Link Unit can be treated just like the area
allocated to an Expansion I/O Unit. The difference is that the bits are not actual
I/O points, but I/O bits in the DeviceNet master.
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).

CPM1A programs can be created or edited with a Programming Console or a
personal computer running SYSMAC Support Software (SSS).
A CQM1-PRO01-E or C200H-PRO27-E Programming Console can be con-
nected to the CPM1A as shown in the following diagram.
