Section 3-31
3-31-9 DISABLE PERIPHERAL SERVICING: IOSP(287) (CS1-H/CJ1-H/
CJ1M Only)
Purpose
Disables peripheral servicing during program execution in Parallel Processing
Mode or Peripheral Servicing Priority Mode.
For details on the Parallel Processing Mode and Peripheral Servicing Priority
Mode, refer to Section 6 Advanced Functions in the CS/CJ PLC Programming
Manual.
Note This instruction is supported by CS1-H, CJ1-H, and CJ1M CPU Units only. It
cannot be used with CS1, CJ1, or CS1D CPU Units.

Description
Use IOSP(287) in a cyclic task in Parallel Processing Mode (with Synchro-
nous or Asynchronous Memory Access) to disable the following kinds of
peripheral servicing. Peripheral servicing will be enabled again when
IORS(288), the ENABLE PERIPHERAL SERVICING instruction, is executed.
• Event servicing with Special I/O Units
• Event servicing with CPU Bus Units

• CS/CJ-series program
(Program using indirect Index
Register addressing)
• CS/CJ-series program
In this case, IR0 contains 10001 hex. The
data area address corresponding to PLC
memory address 10001 hex is D00001, so
#1234 is transferred to D00001.

• CV-series program
In this case, IR0 contains 10001 hex.
Since the data area address
corresponding to CS/CJ-series PLC
memory address 10001 hex is D00001,
TOCV(285) stores the CV-series PLC
memory address for D00001 (2001 hex)
in destination word D00200.

In the CV-series PLC, the destination of the
MOV(021) instruction is indirectly addressed
(in binary mode) through D00200, so #1234 is
transferred to D00001.
PLC Setup
Indirect DM data:
When indirect DM addresses are in binary, the
content of the DM word is treated as a PLC
memory address and specifies the
corresponding address in I/O memory.
