Disc0XSWI1.InRef5.setSrcRef OPERAND
Range: any FlexLogic operand
Default: OFF
This setting is used to select a FlexLogic operand that declares to IEC 61850 services that disconnect switch 1 is selected
for local control. While the selected operand is asserted, Disc0XSWI1.Loc.stVal is true and IEC 61850 commands to
DiscCSWI1.Pos and Disc0XSWI1.Pos are not accepted, and a Negative Response (-Rsp) is issued with the REASON CODE
of Blocked-by-switching-hierarchy.
XSWI1 INTERLOCK OPN
Range: any FlexLogic operand
Default: ON
This setting is used to select a FlexLogic operand that declares to IEC 61850 services that interlocking conditions are not
acceptable for opening disconnect switch 1. While the selected operand is asserted, the value of DiscCILO.EnaOpn.stVal
is false. If a SelectWithValue or Operate service with ctlVal false and with Check.Interlock-check true is requested of
DiscCSWI1.Pos or Disc0XSWI1.Pos and the selected operand is not activated, a Negative Response (-Rsp) is issued with
the REASON CODE of Blocked-by-interlocking.
XSWI1 INTERLOCK CLS
Range: any FlexLogic operand
Default: ON
This setting is used to select a FlexLogic operand that declares to IEC 61850 services that interlocking conditions are not
acceptable for closing disconnect switch 1. While the selected operand is asserted, the value of DiscCILO.EnaCls.stVal is
false. If a SelectWithValue or Operate service with ctlVal true and with Check.Interlock-check true is requested of
DiscCSWI1.Pos or Disc0XSWI1.Pos and the selected operand is not activated, a Negative Response (-Rsp) is issued with
the REASON CODE of Blocked-by-interlocking.
XSWI1 Pos ctlModel
Range: status-only, direct-with-normal-security, sbo-with-normal-security, direct-with-enhanced-security, sbo-with-
enhanced-security
Default: sbo-with-enhanced-security
This setting selects the control model that clients must use to successfully control the disconnect switch 1 signals
marked Disc0XCBR1.PosOpn.ctlVal and Disc0XCBR1.PosCls.ctlVal on the Disconnect Switch Logic diagram in the Settings
> System Setup section later. These signals force a disconnect switch trip or close control while the operand selected by
setting XSWI1 ST.LOC OPERAND is not active.
"sbo" here is select-before-operate. Enhanced security means that the D30 reports to the client the disconnect switch 1
position the end of the command sequence.
