Types of Interrupt Tasks

I/O Interrupts (CS Series
Only)
Scheduled Interrupts
Power OFF Interrupt
Cyclic task (including
extra cyclic task)
Cyclic task (including
Multiple tasks
extra cyclic task)
Interrupt tasks can be executed at any time in the cycle if any of the following
conditions are in effect.
The built-in interrupt inputs and high-speed counter inputs on a CJ1M CPU
Unit can be used to activate interrupt tasks. Refer to the CJ Series Built-in I/O
Operation Manual for details.
Note The CS1D CPU Units for Duplex-CPU Systems do not support interrupts.
With the CS1D CPU Units, interrupt tasks can be used only as extra cyclic
tasks.
The I/O interrupt task will be executed when input to the Interrupt Input Unit is
ON.
A scheduled interrupt task will be executed at fixed intervals.
The power OFF interrupt task will be executed when power is turned OFF.
