How can I manually determine internal connections between COM terminals for Programmable Controller?

The "number of circuits" given in the I/O Unit specifications is the same as the number of commons. Refer to C200HX/HG/HE Operation Manual and CS1 Series Programmable Controller Operation Manual.

Notation Example                                                  

Number of circuit (in specifications)         Description

32 (32 points/common, 1 circuit) to    (32 points/common) x1 circuit (1 common) = 32 points

64 (32 points/common, 2 circuits) to   (32 points/common) x 2 circuits (2 commons) = 64 points

96 (16 points/common, 6 circuits) to    (16 points/common) x 6 circuits (6 commons) = 96 points

For information on specific common terminals wiring and configuration, refer to the terminal connection diagram in the same manuals.
