Does anyone know where I can find the PID block algorithm in the Foxboro documentation? Alex, I already looked for B0193JU and all I can find is a reference to this 1990 document but I can not find the document itself. I have already searched Foxboro's Web site and all I could find is 2 CARs and a reference to the B0193JU document...all of which were no help. Regards, Michael L.
