16-point I/O Units
There isn't a registered I/O table in CQM1H PCs, so it isn't necessary to regis-
ter an I/O table from a Programming Device. Just mount the desired Units in
the PC and I/O is allocated automatically.

I/O bits are allocated in one-word units, even for I/O Units that require only 8
bits.
One word allocated
The unused input bits (08 to 15) cannot be used as work bits, but unused out-
put bits (08 to 15) can be used as work bits.
One input word is allocated to each 16-point Input Unit and one output word is
allocated to each 16-point Output Unit. Input or output points 0 to 15 corre-
spond to bits 00 to 15 of the allocated word.
