Example for usage within ST-editor
PROGRAM Test
VAR
result1 : SINT;
result2 : SINT;
END_VAR
result1 := SEL_SINT(G := FALSE, IN0 := SINT#
1
, IN1 := SINT#
2
); (* The variable
'result1'
evaluates to
'SINT#1'
. *)
result2 := SEL_SINT(G := TRUE, IN0 := SINT#
1
, IN1 := SINT#
2
); (* The variable
'result2'
evaluates to
'SINT#2'
. *)
END_PROGRAM
