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"
