Hi guys, I have a problem with a wrapping machine that has 4 pid loops to control sealing heaters, and when the machine starts the temperature goes low and when the machine stops the temperature overshuts high, is there any good example on how to control temperature with an analog input to measure and digital output to control the heater? I have attached the file in case somebody wanted to take a look at it. Thanks for your help. Señor Jumper Cpr55101.rss
