The CP1L can function as a slave to a CompoBus/S Master Unit (or SRM1
CompoBus/S Master Control Unit) when a CP1W-SRT21/CPM1A-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 CPU Unit.
Special flat cable or VCTF cable
From the standpoint of the CP1L CPU Unit, the 8 input bits and 8 output 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 allo-
cated 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.

If the temperature data is
non-negative, binary data is
converted to BCD data.

If the temperature data is negative,
binary data is converted to BCD data.
