The default values of the inputs BEH, OPCNT, EEHEALTH and
OPCAP are set to -1 to denote that they are not connected.
12.4.8.5 Operation principle
GUID-D2679E0E-ABB5-46F0-AD9C-F6E8E8099534 v1
The proxy for signals from switching device via GOOSE (XLNPROXY) is
intended to be used when the switch (XCBR) is modelled and controlled in a
breaker IED or similar unit on the process bus. XLNPROXY packages the signals
from the GOOSE receive function, normally GOOSEXLNRCV, into the same
format as used from SXCBR to SCSWI. It makes a similar evaluation of the
command response as SXCBR when a command is issued from the connected
SCSWI.
12.4.8.6 Position supervision
GUID-95C72346-A577-4F0A-8584-8E1593B9B947 v1
XLNPROXY has two outputs for position indication: OPENPOS and CLOSEPOS.
Position is a double point indication and the OPENPOS and CLOSEPOS are binary
outputs intended to be used for condition logics to protection and control functions
Normally, the position outputs, OPENPOS and CLOSEPOS, follow the value of
the input POSVAL. However, if the POSVAL_V input is FALSE, the
communication is lost (COMMVALID = FALSE), or the quality of the position
received is bad, the OPENPOS and CLOSEPOS are both set to FALSE.
12.4.8.7 Command response evaluation
GUID-A2CDC1AE-A6F5-478B-B6E5-3442C54212D8 v1
The command evaluation is triggered through the group input XIN that is
connected to the SCSWI function controlling the switch.
If an operation is initiated by the SCSWI, the XLNPROXY function checks if the
switch is blocked for the operation direction and that the position moves to the
