How to Use PID Instruction in Mitsubishi PLC

PID Instruction executes PID control which changes the output value according to the input variation.

Once the target value (s1), measured value (s2) and PID parameters (s3) to (s3)+6 are set and the program is executed, the operation result (MV) is transferred to the output value (d) at every sampling time. The sampling time is specified by (s3).

Lets see the details of parameters.

First start Parameters i:e: defined by S3

Now suppose in program D510 is set as S3, shown in below image:
