6-1-2 I/O Allocation Concepts
The CPU Unit automatically allocates I/O bits to the Expansion I/O Units and Expansion Units, if con-
nected when the power supply is turned ON.
It is not necessary to specify I/O bits allocation.
z
Input bits are allocated from CIO 0 and output bits are allocated from CIO 100
The first word from which input bits are allocated is CIO 0. The first word from which output bits are allo-
cated is CIO 100. These cannot be changed.
z
Words Allocated by the System and the Number of Connected Units
The starting words for inputs and outputs are predetermined for a CP2E CPU Unit. Input bits in CIO 0,
or CIO 0 and CIO 1, and output bits in CIO 100, or CIO 100 and CIO 101, are automatically allocated to
the built-in I/O on the CPU Unit.
The words from which bits are allocated by the system and the number of Expansion I/O Units and
Expansion Units that can be connected are given in the following table.
z
Application Example: CPU Unit with 40 I/O Points
For a CPU Unit with 40 I/O points, a total of 24 input bits are allocated to the input terminal block. The
bits that are allocated are input bits CIO 0.00 to CIO 0.11 (i.e., bits 00 to 11 in CIO 0) and input bits CIO
1.00 to CIO 1.11 (i.e., bits 00 to 11 in CIO 1).
In addition, a total of 16 output bits are allocated to the output terminal block. The bits that are allocated
are output bits CIO 100.00 to CIO 100.07 (i.e., bits 00 to 07 in CIO 0) and output bits CIO 101.00 to CIO
101.07 (i.e., bits 00 to 07 in CIO 1).
