(Process) (Redundant)
• [RnPCPU (redundant)] If these instructions are used in a program executed in both systems, there are restrictions on their operation in the standby system
when the redundant system is in backup mode. ( MELSEC iQ-R CPU Module User's Manual (Application))
These instructions stop the PID operation of the loop number in the device specified by (s).

Processing details
• These instructions stop the PID operation of the loop number in the device specified by (s). The loop stopped by the
PIDSTOP(P) instruction does not restart PID operation even if the PIDINIT(P) instruction is executed.
• Each instruction holds operation data while the loop is stopped.
Operation error
Error code Description

3405H Out-of-range data is set in the device specified by (s).
• The specified loop number does not exist.
• The specified value is other than 1 to 32.
3422H The PIDINIT(P) and PIDCONT(P) instructions are not executed before the PIDSTOP(P) instruction.
