SETTINGS GROUPS
The 61850 standard provides for the ability to monitor, edit, and change setting groups in a relay through a series of ser-
vices operating on Setting Group Control Block values. There is one SGCB in LLN0 in LD1 in the UR as, at present, the
other LDs do not support multiple setting groups The default value of
SETTING GROUPS
is Disabled. In order for 61850 and/
or UR setting group control to function, the
SETTING GROUPS FUNCTION
must be set to Enabled.
The active setting group in the UR is settable from either the value set via a FlexLogic operand in the UR (present practice)
or a SelectActiveSG command from a 61850 Client. For both the UR and IEC 61850, the default active setting group is "1".
A 61850 SelectActiveSG command sets one of the internal Non-Volatile flags (61850 SG Level x) that represents the
requested Active Setting Group shown as follows:
On power-up or restart, the previously selected 61850 SG Level x is re-instated. Similarly, the input to the setting group
control in the UR can be designed with Non-Volatile latches to achieve the same effect.
The setting groups menu controls the activation and deactivation of up to six possible groups of settings in the
GROUPED
ELEMENTS
settings menu. The faceplate Settings In Use LEDs indicate which active group (with a non-flashing energized
LED) is in service.
