Note
1. m:
“m” denotes the last input word allocated to the CPU Unit, or to the pre-
vious Expansion Unit or Expansion I/O Unit if one is already connected.
n:
“n” denotes the last output word allocated to the CPU Unit, or to the pre-
vious Expansion Unit or Expansion I/O Unit if one is already connected.
2. Because the CPM2C-MAD11 Analog I/O Unit and the CPM2C-TS001/101
Temperature Sensor Units require 2 I/O words each, only 4 of these Units
can be connected to the PC. (The CPU Unit itself requires one input word
and one output word.) A different Unit, such as an Expansion I/O Unit or the
CPM2C-SRT21 CompoBus/S I/O Link Unit, can, however, be connected in
addition to 4 Analog I/O Units or Temperature Sensor Units.

2 analog inputs
Input 0: word (m+1)
Input 1: word (m+2)
1 analog output
Output 0: word (n+1)
