Dear List, Our process engineer shoot the following questions to us early in the morning today. I must admit, my knowledge on the the following topic is quite sketchy. Appreciate if the list could shed some light and/or point me to the literatures that can explain the following: - What is the principle of tuning in the Foxboro PIDE & PIDA - is it load change or setpoint change or what? - What is the underlying difference between PIDA & PIDE in terms of auto tuning methodology? - Does Foxboro have model-based tuning techniques? - How do we configure a simple auto-tuner using PIDE & FBTUNE? And yes, she did read the Focdoc :) Best regards, Nurul Izzah _______________________________________________________________________ This mailing list is neither sponsored nor endorsed by Invensys Process Systems (formerly The Foxboro Company).
