5.5. Reading/Writing to Parameters with Index
Indexed parameters such as 10-11 or 10-12 need special handling since DeviceNet does not sup-
port indexed addressing. The way to handle this in the frequency converter is to use par. 10-30
Parameter Data Types , which serves as an index pointer. Set up the pointer before each read/
write of an indexed parameter.
NB!
If two masters access this feature at the same time, incorrect data may be gener-
ated.
5.5.1. Example
Write 16-10 in index 2 in par. 10-12 Process Data Config Read .
First, set up the index pointer in par. 10-30
Array Index . In this example index 2:
The next step is to write the data (in this ex-
ample 16-10) to par. 10-12.
