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.
