Group Select
Range 01h to FFh (Bit Coded)
This parameter determines which group to address. Refer to the following
example:
b7 b6
Group 8 Group 7
Example:
To address Group 1, 2, and 4, the Group Select value should be D0h. If an
individual slave should be addressed, the correct group selection must also be
made, because the slave will ignore the message if it does not belong to the
requested group(s).
What group(s) a slave belongs to is determined during network configuration,
and is downloaded during initialization to each slave via the PROFIBUS telegram
Set_Prm.
