1. I/O direct interrupt, which is the change of interrupt input from the built-in input unit on the CPU rack (0→1; 1→0).
2. Counting interrupt, the built-in input pulse of the CPU unit of the PLC is counted, and the interrupt is executed when the count reaches the set value.
3. Timing interrupt, the built-in timer of the CPU unit of the PLC is interrupted at a certain time interval.
4. High-speed counting interrupt, the built-in high-speed counter of the CPU unit of the PLC counts the input pulses, and the count reaches the set value, or the interrupt is executed by regional comparison.
5. When the CP1 series PLC is connected with CJ or other series of high-function I/O units or CPU high-function units, if the interrupt generated by these units is received, the CPU unit of the CP1 series PLC will immediately respond to the interrupt and execute the interrupt subroutine.
The order of priority of the five types of interrupts from highest to lowest is as follows: external interrupts> direct I/O interrupts> count interrupts> high-speed count interrupts> timed interrupts.
Within the same interrupt level, interrupt tasks with a small number take precedence over interrupt tasks with a large number.
