The XCBR1 SYNCCHECK CLS setting is used to supervise a close command with a synchrocheck condition within XCBR
logical node. If a Close with SynchroCheck is requested (through a SelectWithValue service) and the SynchroCheck condi-
tion is not satisfied, a Negative Response (-Rsp) is issued with the REASON CODE of Blocked-by-synchrocheck.
The XCBR1 INTERLOCK OPN/CLS settings are used to assign an operand, which is linked into the EnaOpn or EnaCls
INTERLOCKED inputs respectively of the XCBR. When this operand is asserted, XCBR logical node inhibits execution of
the open and close commands respectively. If select before operate (SBO) with Extended Security is requested and Inter-
lock condition exists, the UR responds with a Negative response (-Rsp) with the Reason Code Blocked-by-interlocking.
The XCBR1 Pos ctlModel setting is used to select control model per IEC 61850-7-3. The following control models are sup-
ported by URs:
0 — Status only
1 — Direct control with normal security (direct-operate)
2 — SBO control with normal security (operate-once)
3 — Direct control with enhanced security (direct-operate)
4 — SBO control with enhanced security (operate-once)
See IEC 61850-7-2 for complete details on these control models.
The
XCBR1 P
os sboTimeout setting is used to select SBO timeout value. To be successful, the IEC 61850 "operate" com-
mand must be executed after the "select" command within the XCBR1 Pos sboTimeout setting value.
The disconnect switch configuration settings are shown below. Changes to these values will not take effect until the UR is
restarted:

XSWI CONFIGURATION
The CLEAR XSWI1 OpCnt setting represents the disconnect switch operating counter. As disconnect switches operate by
opening and closing, the XSWI operating counter status attribute (OpCnt) increments with every operation. Frequent switch
operation may result in very large OpCnt values over time. This setting allows the OpCnt to be reset to “0” for XSWI1.
Since GSSE/GOOSE messages are multicast Ethernet by specification, they are not usually be forwarded by net-
work routers. However, GOOSE messages may be forwarded by routers if the router has been configured for VLAN
functionality.
