Example: To address Group 1, 2 and 4, the Group Select value should be 0Dh. If an
individual slave should be addressed the correct group selection must also be made, since the
slave will ignore the message if it does not belong to the requested group(s).
The group(s) a slave belongs to is determined during network configuration with WI Series
Configuration Software, and is downloaded during initialization to each slave via the
Profibus telegram Set_Prm.
