6F2S1931 (0.20)Centralized GRB200(Soft: 030, 031, 032, 033, 034)- 320 -(ii) Synchronization using IRIG-BExample of IRIG-B synchronizationThe IRIG-B method is possible when a synchronization signal in the IRIG-B format is provided.The synchronization signal is transferred using the IRIG-B000 module†.IEDIRIG-B signalgenerator UnitA1A3SignalGNDIRIG-B000†Clock10:00 1/2[Time] +2012-11-21 10:00:05[Format]YYYY-MM-DD HH:mm:ss[ActiveSyncSrc]IRIG-BFigure 4.7-5 IED connected with the signal generator unit using IRIG-B000 module†Note:See ChapterTechnical description: Signal processing and communication module.Setting procedureThe user should make the following steps in respective IEDs.1) Set IRIG-B for the setting [Time Sync Src]; then set On for the setting [IRIG-SYNC].2) Check that the IRIG-B is shown under the ActivSyncSrc, as shown in Figure 4.7-6.Clock10:00 1/2[Time] +2012-11-21 10:00:05[Format]YYYY-MM-DD HH:mm:ss[ActiveSyncSrc]IRIG-BCheck “IRIG-B” being shown under ActiveSyncSrc.Figure 4.7-6 Time setting for IRIG-BSetting year in IRIG-BWhen the IRIG-B data is generated in the IEEE C37.118 / IRIG-B000 format, the user shouldset On for setting [USE_BCDYEAR]. Conversely, when the IRIG-B data with absence theC37.118† is generated, Off should be set for the setting [USE_BCDYEAR].†Note: “Year” is informed from the IED clock itself when the C37.118 is absent.Setting UTC/local timeWhen the IRIG-B data is generated in the UTC†, set Off for the setting [USE_LOCALTIME].Conversely, when the IRIG-B data is generated in the local time‡, set On for setting[USE_LOCALTIME]; set Off for the setting [IS_UTC_base].†Note:We shall see the settings of the UTS in section 4.7.4.‡Note:In the IRIG-B signal generator unit, the DST settings should be corresponded to
