Hello,
Funcion blocks (FB) has several conditions which all have to be met to activate a relay . In other words it acts as AND operator.
Is it electrically allowed to conect FB outpur relays in parallel to have OR function ... For example our customer wants to have heating from cylinder when original FB2 conditions met ( based on return and cylinder temp difference) OR cylinder temp is above 30 degrees
