CONT_S PID

hi everyone
If we have a tow-state valve (open/close) with tow motors (first for opening & second for closing) can I use the FB42 (CONT_S) for controlling this valve with PID Controller by enter set point value and read the feedback (witch is a temperature ) from the output of the valve

Hello

I think so that you can use the FB42 "CONT_S". This FB has two outputs, QLMNUP (Typ: bool) for Manipulated signal up and QLMNDN for Manipulated signal down. Please see the informations of the online help for description of function and the input parameters. Further informations you will find in the FAQ:
