Note:
The instruction is used to implement the PID operation. The PID operation is conducted only when PID
instruction is performed by PLC. PID stands for Proportion, Integral and Derivative. The PID control is widely
applied to mechanical equipment, pneumatic equipment and electronic equipment.
Function Explanation
There is no limit to how many times the instruction can be used. However, the variable specified by
I_MV can not be used by other program repeatedly.
PID instruction can only be used in the cyclic task.
As long as PID is scanned, according to the sampling time specified by CYCLE, the PID operation
is implemented and the MV value is output directly. The PLC will not calculate automatically
