When peripheral servicing has been disabled with IOSP(287), it will remain disabled until IORS(288) is
executed, END(001) is executed, or PLC operation is stopped.
Note • IOSP(287) cannot be executed in an interrupt task. An error will occur and the Error Flag will be turned
ON if IOSP(287) is executed in an interrupt task.
• IOSP(287) cannot disable peripheral servicing in more than one task. If it is necessary to disable periph-
eral servicing in more than one task, program IOSP(287) separately in each task.
IORS
Use IORS(288) in a cyclic task to release the prohibition on peripheral servicing by IOSP(287), the
DISABLE PERIPHERAL SERVICING instruction.
Note 1 It is not necessary to program IORS(288) with an execution condition.
2 IORS(288) cannot be executed in an interrupt task. An error will occur and the Error Flag will be turned ON
if IORS(288) is executed in an interrupt task.

When W0.00 is ON,
execution of peripheral
servicing is disabled
between IOSP(287) and
IORS(288).
Enables execution of
