6.2.1 Example of parametrising
Programmers can use the following example as an orientation
for implementation.
Example
Wrote
setpoint
position
Record
3 = 27.89 mm
Parameter request
(PLC output data)
ReqID = 8
(= Write value)
PNU
= 404 (= Record list
setpoint value)
IND
= 3
(= Record 3)
Value = 27.89 * 100 = 2789
Parameter response
(PLC input data)
ResID = 5
(= Value has been
transmitted)
PNU
= 404 (= Record list setpoint
value)
IND
= 3
(= Record 3)
Value = 2789
