12.4.6.6 Interaction with switch on process bus
GUID-1E243260-55FC-4DA6-A314-649E0B95A2B9 v1
When the switches are modelled and controlled in a breaker IED, the information
from the switches is limited to those described in the IEC 61850 standard.
Since there is no expression for distributing the cause of failure over GOOSE, the
XLNPROXY function is used for evaluating the causes normally evaluated by the
SXCBR function.
Further, in some cases selection may also be used on the model of the switch in the
breaker IED, in case multiple controllers may access it via GOOSE. In such a case,
if the input for the stSeld data attribute in the XLNPROXY function is connected,
SCSWI automatically awaits that the switch is selected before accepting the
selection. Also, if the seSeld data attribute is set before the selection is requested,
the selection request fails.
