The relay supports remote changing of the used parameter setting group. The six possible setting groups in the relay are coded as objects Characteristic 1…Characteristic 6 using standard information numbers 23…28.
On the relay's native IEC 61850 model level the parameter setting group change object is also a setting parameter in itself, not a process object as is assumed in the IEC 60870-5-103 standard. In a normal case, any parameter setting change in the relay requires that the client first reserves the parameter setting rights, then changes the setting and finally stores the change. An exception to this is the Parameter setting group change parameter. Writing remotely to this parameter automatically includes reservation and storing. Consequently, the setting group writing fails if simultaneous parameter settings are edited via the HMI, or remotely from another master.
