1-2-6 CompoBus/S I/O Link Connections

A CompoBus/S I/O Link can be used to create an I/O link (remote I/O) of 8 input points and 8 output points with a CompoBus/S Master Unit or SRM1 PC. The connection is made through a CompoBus/S I/O Link Unit.

From the standpoint of the CPM1A CPU Unit, the area allocated to the Compo-

Bus/S 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

Master Unit.
