Command 9 Read Device Variables with Status

Message posted by Jens ( : 212.88.130.46) on 06 October 2011 at 13:06:34.

Hello again,

i have another queestion concerning universal commands.
The command 9 has one byte in its Request Data for every device variable the Master is requesting (up to 8 Device Variables).
Does the device check the Device Variable codes in the Request data or does it only count the nuumber of bytes received an then sends the variables 0 - 7.

The specification says:
If the device receives 1,2,3,4,5,6 or 7 Request data Bytes it must return only the corresponding number of the device Variables.

In the respone data, there is a response code 14 (Warning, Dynamic Variables Returned for Device Variables).
I have only the Primary Variable, does that mean, that my device has always to return Response Code 14?

Thanks for your help.

Jens
