Mitsubishi FX3U PID Function block

[onboardx]

Hi guys. I want to heating control but I could not make the settings of pid control fb. I didn't see any changes at the manipulated value? Can you help me?

I'm guessing here since I am not a Mitsi user but it looks to me like the Pretuning input is being held ON and that is moving the PretuningManipulatedValue directly to the output. Is it in the middle of an auto-tune function?

Hi, Keith. I downloaded sample program for heating control. I added pictures of ladders step by step. Can you help me where I make a mistake.
