If the PLC you're using has a PID function in its instruction set, then you can use it. Not all models have it. | |

I agree with Steve statements after you find out if your PLC can handle it your next question is do I need the full PID loop or just PI. | |

I think you'll be surpised by the capabilities of modern PLC's with respect to PID functions. Depending on the brand you should find full PID function control blocks. Many also have optional "PID" I/O modules that provide auto tuning. Also there are several third party PID tuning software packages (like Expertune) that can auto tune a loop running inside the PLC. | |

Are you asking for information on tuning parameters for a PID? | |

This may be of some assistance, once you understand PID then look for whatever device to have the features to do what you need. | |
