6 I/O Allocation
6-4
CP2E CPU Unit Software User’s Manual(W614)
Expansion Units and Expansion I/O Units connected to the CPU Unit are automatically allocated input
bits and output bits in words following those allocated to the CPU Unit.
For example, if a CPU Unit with 40 I/O points is used, CIO 0 and CIO 1 are allocated for inputs and CIO
100 and CIO 101 are allocated for outputs. Thus, words from CIO 2 onward for inputs and words from
CIO 102 onward for outputs are automatically allocated to the Expansion I/O Units and Expansion Units
in the order that the Units are connected.
There are Expansion I/O Units for expanding inputs, for expanding outputs, and for expanding both
input and outputs.
I/O bits starting from bit 00 in the next word after the word allocated to the previous Expansion Unit,
Expansion I/O Unit, or CPU Unit are automatically allocated. This word is indicated as “CIO m” for input
words and as “CIO n” for output words.
