Performing PID operation
S(P).PIDCONT
These instructions measure the sampling cycle and perform PID operation when the execution command turns on.

Description, range, data type
*1 When specifying setting data by using a label, define an array to secure enough operation area and specify an element of the array
label.
■
Applicable devices
• [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. (
