Index
To create the index, the relevant parameter number in the SDO-ID must be converted. This is
performed according to the following formula:
SDO-ID = Device-ID + Parameter number
Example
FI 1, Parameter P102
SDO-ID = 2800
hex
+ 102
dez
= 2800
hex
+ 66
hex
= 2866
hex
Sub-index
The creation of the Sub-Index depends on the structure of the relevant parameter and is coded
according to the following pattern.
NORD-specific POWERLINK
