That receiving function blockhas outputs that can be used, for example, to control high voltage apparatuses inswitchyards. For local control functions, the local HMI can also be used. Togetherwith the configuration logic circuits, the user can govern pulses or steady outputsignals for control purposes within the IED or via binary outputs.Figure 115 shows an application example of how the user can connectSINGLECMD via configuration logic circuit to control a high-voltage apparatus.This type of command control is normally carried out by sending a pulse to thebinary outputs of the IED. Figure 115 shows a close operation. An open breakeroperation is performed in a similar way but without the synchro-check condition.SinglecommandfunctionSINGLECMDCMDOUTyOUTyClose CB1&User-definedconditionsSynchro-checkConfiguration logic circuitsen04000206.vsdIEC04000206 V2 EN-USFigure 115: Application example showing a logic diagram for control of a circuitbreaker via configuration logic circuits1MRK 505 393-UEN B Section 12ControlLine differential protection RED650 2.2 IEC 273Application manual
