Lower_Limit as Real(Brief="Lower limit of the range",Default=0);

VARIABLES
in In as Real(Brief="Input without limiting",Protected=true,PosX=0,PosY=0.5);
out Out as Real(Brief="Output once limited",Protected=true,PosX=1,PosY=0.5);

EQUATIONS
if In>=Upper_Limit then
        Out=Upper_Limit;
else
        if In<=Lower_Limit then
                Out=Lower_Limit;
