Corporate recently sent in an engineer to "help" our Engineers with a problem PID in one of our process. I had been playing with it on third shift, but dummy that I am day work always erased my parameters. Didn't believe we coudl make it work since they couldn't. Well when the day shift team got tired and left the Engineer with me I was able to demo some of the parameters we had been using. Turns out I was really close to a finished tune. About 30 minutes after my numbers went in the trune was ddeclared done. Thanks to the MRPLC PID Gurus like Peter, Ron and Tim and others I have forgotten for the great training and advice.
