      Re: How to set CONTROLLERTYPE to heating

      Hi Martin
      I'm againg on the same topic after some months.
      I'm not able to set (I'm using an ST program) the value of input "ControlType" of block B31_REVERSE_ON_OFF_CONTROL_SEQUENCE.
      I search into help but there is no example of ST program that explain how to set the input.

      I Tried

      PROGRAM B31_TEST
      VAR IN1, IN2:REAL;
      O1: BOOL;
      FB: LIB.CORE.V1_0.B31_REVERSE_ON_OFF_CONTROL_SEQUENCE;
      END_VAR
      FB(X:=IN1,CONTROLLERTYPE:=COOLING, W:= IN2);
      O1:= FB.OUT;
      END_PROGRAM

      but
      i get the error "can not find the object 'COOLING' in the current context"
