The realizations of these functions are done with SXCBR representing a circuitbreaker and with SXSWI representing a circuit switch that is, a disconnector or anearthing switch.Circuit breaker (SXCBR) can be realized either as three one-phase switches or asone three-phase switch.The content of this function is represented by the IEC 61850 definitions for thelogical nodes Circuit breaker (SXCBR) and Circuit switch (SXSWI) withmandatory functionality.8.2.1.4 Proxy for signals from switching device via GOOSE XLNPROXYGUID-2DA1E47C-5A9A-4C53-8D60-7B1729EF6B90 v1The purpose of the proxy for signals from switching device via GOOSE(XLNPROXY) is to give the same internal representation of the position status andcontrol response for a switch modeled in a breaker IED as if represented by aSXCBR or SXSWI function.The command response functionality is dependent on the connection of theexecution information, XIN, from the SCSWI function controlling the representedswitch. Otherwise, the function only reflects the current status of the switch, suchas blocking, selection, position, operating capability and operation counter.Since different switches are represented differently on IEC 61850, the data that ismandatory to model in IEC 61850 is mandatory inputs and the other useful data forthe command and status following is optional. To make it easy to choose whichdata to use for the XLNPROXY function, their usage is controlled by theconnection of each data’s signal input and valid input. These connections areusually from the GOOSEXLNRCV function (see Figure 41 and Figure 42).Section 8 1MRK 511 423-UEN AControl116 Bay control REC650 2.2 IECApplication manual
