9-5 CompoBus/S I/O Link Units
The CP1E CPU Unit can function as a slave to a CompoBus/S Master Unit when a CP1W-SRT21 Com-
poBus/S I/O Link Unit is connected. The CompoBus/S I/O Link Unit establishes an I/O link of 8 inputs
and 8 outputs between the Master Unit and the PLC.
From the standpoint of the CP1E CPU Unit, the 8 input bits and 8 output bits allocated to the Compo-
Bus/S I/O Link Unit are identical to input and output bits allocated to Expansion I/O Units even though
the CompoBus/S I/O Link Unit does not control actual inputs and outputs, i.e., I/O is performed for I/O
memory in the CPU Unit to which the CompoBus/S Master Unit is mounted.
