Input Interrupts
There are two input interrupts in the CPM1A 10-point I/O CPU and four in the 20-, 30-, and 40-point I/O CPUs.
Input interrupts are available in two modes.
10-point I/O CPU
Input Interrupt Mode
If an input interrupt occurs, the regular program shuts down irrelevant of the cycle time, and the interrupt processing program is
executed immediately.
Counter Mode
When the number of external signals counted at high speed reaches a specified number of counts, the regular program shuts down, and the inter-
rupt processing program is executed at fixed counts. The count can be set between 0 and 65535.

Application Example:
Cutting Metal Sheets to Specified Lengths
The proximity sensor detects the edge of a metal plate to operate
the cutter. Metal sheets can be cut continuously to the specified lengths
at a high speed.
