of the pulse can be set using the tPulse parameter. Also, being accessible on thesingle line diagram (SLD), this function block has two control modes (settablethrough CtlModel): Dir Norm and SBO Enh.12.6 Generic communication function for Double Pointindication DPGAPC SEMOD55384-1 v412.6.1 IdentificationGUID-E16EA78F-6DF9-4B37-A92D-5C09827E2297 v3Function description IEC 61850identificationIEC 60617identificationANSI/IEEE C37.2device numberGeneric communication function forDouble Point indicationDPGAPC - -12.6.2 Application SEMOD55391-5 v8Generic communication function for Double Point indication (DPGAPC) functionblock is used to send double point position indication to other systems, equipmentor functions in the substation through IEC 61850-8-1 or other communicationprotocols. It is especially intended to be used in the interlocking station-widelogics. To be able to get the signals into other systems, equipment or functions, onemust use other tools, described in the Engineering manual, and define whichfunction block in which systems, equipment or functions should receive thisinformation.More specifically, DPGAPC function reports a combined double point positionindication output POSITION, by evaluating the value and the timestamp attributesof the inputs OPEN and CLOSE, together with the logical input signal VALID.When the input signal VALID is active, the values of the OPEN and CLOSE inputsdetermine the two-bit integer value of the output POSITION. The timestamp of theoutput POSITION will have the latest updated timestamp of the inputs OPEN andCLOSE.When the input signal VALID is inactive, DPGAPC function forces the position tointermediated state.When the value of the input signal VALID changes, the timestamp of the outputPOSITION will be updated as the time when DPGAPC function detects thechange.Refer to Table 25 for the description of the input-output relationship in terms of thevalue and the quality attributes.Section 12 1MRK 505 393-UEN BControl270 Line differential protection RED650 2.2 IECApplication manual
