Index Pointer
Instance Description:
The Danfoss VLT 2800/FCD 300 DeviceNet only use
Instance 1, so always leave this at the value of 1.
Attribute Description:
The attributes for the VLT 2800/FCD 300 parameter
are the last 2 (two) digits of the parameter + 100.
MG.90.B2.02 - VLT is a registered Danfoss trade mark

Reading/writing to parameters with index:
Class 108
Parameters of type indexed (e.g. 915 & 916)
Class 109
need special handling since DeviceNet does
Class 120
not support indexed addressing.
The way to handle this in the VLT 2800/FCD 300, is
by using the the Danfoss Class 120. which serves
as an index pointer. The pointer has to be set up
before every read/write of an indexed parameter.
Example:
Write 518 in index 2 in parameter 916 PCD Read:
First setup the index pointer in class 120.
In this example index 2:
Class
120 Dec
78 Hex
Next step is to write the data (in this example
518) to parameter 916 PCD Read
Class
109 Dec
6D Hex
