PRODUCT SETUP
Switch 1
The UR disconnect switch control and status monitoring elements have certain settings that configure how the IEC 61850
protocol interacts with these elements. These settings are described in this section. See the Settings > System Setup >
Disconnect Switches section later in this chapter for details on the operation of the disconnect switch control elements.
Navigate to Settings > Product Setup > Communications > IEC 61850 > System Setup > Switches > Switch 1 to access
the settings that configure the IEC 61850 protocol interface with the first disconnect switch control and status monitoring
element. The settings and functionality for the others are similar.

XSWI1 ST.LOC 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.
