Processing details
• These instructions start the PID operation of the loop number in the device specified by (s). These instructions are used to
re-execute the PID operation of the loop number that has been stopped by the S(P).PIDSTOP instruction.
• The S(P).PIDRUN instruction, if executed for a loop number already in progress of PID operation, performs no processing.
Operation error
• [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))
