Syntax
returnstate = InputPoint(pointname, returnflag)
Remarks
Argument Type
returnstate bool
pointname point
returnflag point
Typical Examples
InputPoint(point)
returnflag = FALSE
InputPoint(point, returnflag)
A request is made that the current value of point 'point' should be read. In the
second example, returnflag is set to 'TRUE' when the value is returned from
the PLC.
The value is not returned immediately - it is not possible to use the returned
value in the same script as the InputPoint command. Instead, the value should
be accessed from within an "On Condition" script which has an expression of
'returnflag = TRUE'.
Syntax
returnstate = OutputPoint(pointname)
Remarks
Argument Type
returnstate bool
pointname point
Typical Examples
OutputPoint(result)
The point 'result' is updated with its current value.
The value of a point connected to a PLC is not be set if the point is currently in
a "forced" state.
Syntax
returnpoint = PointExists(pointname)
