Registering The Pid Control Data To The Cpu Module - Mitsubishi Electric MELSEC iQ-R Series Programming Manual

Registering the PID control data to the CPU module

S(P).PIDINIT
RnPCPU
RnCPU RnENCPU
(Process)
• [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 store the PID control data by the number of loops used that is set in the specified device number and later
altogether in the CPU module.
