The illustrations in this section show CPM2A PLCs, but the same functions are available in
CPM2B/CPM2C PLCs unless otherwise stated.
Interrupts
The CPM2-series PLCs provide the following kinds of interrupt processing.
Interrupt Inputs
Interrupt programs are executed when inputs to the CPU Unit’s built-in input points (00003 to 00006) are turned from OFF to ON. Interrupt sub-
routine numbers 000 to 003 are allocated to input points 00003 to 00006.
Interval Timer Interrupts
Interval timer interrupt programs are executed with a precision of 0.1 ms. Interrupt subroutine numbers 000 to 049 are allocated by instructions.
Count-up Interrupts
Input signals to the CPU Unit’s built-in input points (00003 to 00006) are counted at high speed (up to 2 kHz), and the normal program is stopped
and an interrupt program is executed when the count reaches the SV. Interrupt subroutine numbers 000 to 003 are allocated to input points 00003
to 00006.
Count-check Interrupts Using the High-speed Counter
Pulse inputs to the CPU Unit’s built-in input points (00000 to 00002) are counted at high speed (up to 20 kHz or 5 kHz), and an interrupt program
is executed when the present value matches the target value or falls within a given range. Interrupt subroutine numbers 000 to 049 are allocated
by instructions.
Interval Timer Interrupts
The CPM2 has one interval timer (precision: 0.1 ms) that can be set from 0.5 ms to 319,968 ms. There are two interrupt modes: the single-interrupt
mode, in which a single interrupt is executed when the time is up, and the scheduled-interrupt mode, in which interrupts are executed at regular
intervals.
