Programming
With a CPM2C, wire to the input terminals as shown in the following illustration.
Input terminals
Note 1. Refer to the operation manual for your CPU Unit for information on wiring.
2. Input terminal and pin numbers depend on the model. Refer to the CPM2C
Operation Manual (W356) for details.
The following table shows the settings in the PC Setup area related to interrupt
input usage.

Note *Input points 00005 and 00006 do not exist in CPM2C CPU Units with only 10 I/O
points and in CPM2C-S CPU Units.
The settings will go into effect when the mode is changed (from PROGRAM to
MONITOR/RUN) or when the power supply is turned ON to the CPM2A/
CPM2C.
The following table shows the instruction operations related to interrupt input
control.
