Where "n" is the last output word allocated to
the CPU Unit, or previous Expansion Unit or
Expansion I/O Unit.
This section describes how to connect an Analog I/O Unit to the CPU Unit.
A maximum of 3 Expansion Units or Expansion I/O Units, including up to 3 Ana-
log I/O Units, can be connected to one CPM2A or CPM1A PC. When the Analog
I/O Unit is used in combination with other Expansion Units or Expansion I/O
Units, there are no restrictions on the connection order.

CPU Unit
I/O Allocation
I/O is allocated for the Analog I/O Unit in the same way as other Expansion Units
or Expansion I/O Units starting from the next word following the last allocated
word on the CPU Unit or previous Expansion Unit or Expansion I/O Unit. When
"m" is the last allocated input word and "n" the last allocated output word on the
CPU Unit, or previous Expansion Unit or Expansion I/O Unit, the allocation will
be as follows:
