CHAPTER 6 – Functions and Methods
OMRON
Page 64
Revision 2.0
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.
Note:
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’.
OutputPoint
Syntax
returnstate = OutputPoint(pointname)
