Semantic Error (SEM1085): The '...' statement expects an expression of type 'BOOL'.
In an IF statement (ST code), the control expression must return a Boolean value. If a Boolean value is to be evaluated, the expression can be reduced to the variable itself.
The following notations are possible:
In your ST code, another data type than BOOL was specified alone at the underlined position, thus forming no Boolean expression.
