IEC16000072 V1 EN-USFigure 112: Configuration with XLNPROXY and GOOSEXLNRCV where onlythe mandatory data in the IEC 61850 modelling is usedAll the information from the XLNPROXY to the SCSWI about commandfollowing status, causes for failed command and selection status is transferred inthe output XPOS. The other outputs may be used by other functions in the sameway as the corresponding outputs of the SXCBR and SXSWI function.When a command has been issued from the connected SCSWI function, theXLNPROXY function awaits the response on it from the represented switchthrough the inputs POSVAL and OPOK. While waiting for the switch to startmoving, it checks if the switch is blocked for the operation. When the switch hasstarted moving and no blocking condition has been detected, XLNPROXY issues aresponse to the SCSWI function that the command has started. If OPOK is used,this response is given when XLNPROXY receives the signal.If no movement of the switch is registered within the limit tStartMove, thecommand is considered failed, and the cause of the failure is evaluated. In theevaluation, the function checks if the state of the represented switch is indicatingthat the command is blocked in any way during the command, and gives theappropriate cause to the SCSWI function. This cause is also shown on the outputL_CAUSE as indicated in the following table:1MRK 505 393-UEN B Section 12ControlLine differential protection RED650 2.2 IEC 261Application manual
