Other Instructions
Section 3-31
Example
The following example shows IOSP(287) and IORS(288) used to disable
peripheral servicing in a program section.
3-31-10 ENABLE PERIPHERAL SERVICING: IORS(288) (CS1-H/CJ1-H/
CJ1M Only)
Purpose
Enables the peripheral servicing during program execution in Parallel Pro-
cessing Mode that was disabled by IOSP(287), the DISABLE PERIPHERAL
SERVICING instruction.
This instruction is supported by CS1-H, CJ1-H, and CJ1M CPU Units only.

Description
Use IORS(288) in a cyclic task to release the prohibition on peripheral servic-
ing by IOSP(287), the DISABLE PERIPHERAL SERVICING instruction.
It is not necessary to program IORS(288) with an execution condition.
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.
Flags
IOSP
IORS
W00000
When the PLC is in
Parallel Processing
Mode, peripheral
servicing is executed in
parallel.
When W00000 is ON,
execution of peripheral
servicing is disabled
between IOSP(287) and
IORS(288).
Enables execution of
peripheral servicing.
When the PLC is in
Parallel Processing
Mode, peripheral
servicing is executed in
parallel.
