9.3.8.2 Example: Write parameter
For the actuator with device address 5 the limit 1 is to be set to 2000000!
Calculation of the identifier:
Identifier of the parameter channel to the actuator = 600
h
+ device address
600

Sub-index = 2
The index and the sub-index of the parameter 'limit 1' were taken from the directory of
objects (chapter 9.13.2: Description of objects).
