MSKR(692) Operand for Scheduled Interrupts
An I/O interrupt task will be executed when an input to an Interrupt Input Unit turns ON. The maximum
number of tasks that you can create is 32 (interrupt task numbers 100 to 131).
z Executing Interrupt Tasks
To enable I/O interrupts, execute the MSKS(690) (SET INTERRUPT MASK) instruction.
Example: The following example shows execution I/O interrupt task 103 when interrupt input No. 3
of Interrupt Input Unit No. 0 (the leftmost of the two Units 0 and 1) is ON.
Interrupt Input Unit Numbers, Input Numbers, and I/O Interrupt Task Numbers
*1 Interrupt Input Unit numbers are in order from 0 to 1 starting from the CPU Unit.
Operand Set value
N (interrupt identifier) 4: Read scheduled interrupt time (set value) for interrupt task 0 (interrupt task 2)
5: Read scheduled interrupt time (set value) for interrupt task 1 (interrupt task 3)
14: Read present value of internal timer for interrupt task 0 (CJ2M CPU Unit only,
interrupt task 2)
15: Read present value of internal timer for interrupt task 1 (CJ2M CPU Unit only,
interrupt task 3)
