CompoBus/S I/O Link Units Section 9-6
9-6 CompoBus/S I/O Link Units
The CP1L-EL/EM can function as a slave to a CompoBus/S Master Unit (or
SRM1 CompoBus/S Master Control Unit) when a CP1W-SRT21 CompoBus/
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. Up to
three CompoBus/S I/O Link Units, including other Expansion I/O Units, can be
connected to a CP1L-EL/EM CPU Unit.
From the standpoint of the CP1L-EL/EM CPU Unit, the 8 input bits and 8 out-
put bits allocated to the CompoBus/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. The input and output bits
allocated to the CompoBus/S I/O Link Unit are one side of an I/O link between
the slave CPU Unit and the CPU Unit to which the Master Unit is connected.
