6F2S1931 (0.20)Centralized GRB200(Soft: 030, 031, 032, 033, 034)- 319 -4.7.3 Time SynchronizationThe synchronization function can run when a synchronized signal is provided for respectiveIEDs; the user should select one of the following synchronization methods using the setting[Time_Sync_Src]: SNTP method IRIG-B method Binary Input (BI) method Modbus commination method IEC103 method(i) Synchronization using SNTPExample of SNTP synchronizationThe SNTP method is possible when IEDs connect with time-servers. Figure 4.7-3 exemplifiestwo servers are connected with the IEDs using the LAN.Time server1 Time server2IED_1 IED_2LANIED_n………….Figure 4.7-3 Two time servers connected on the LANSetting procedureThe user should make the following steps in respective IEDs.1) Set SNTP for the setting [Time Sync Src]; then set On for the setting [SNTP].2) Set the address of a time server using settings [Server1]. The settings [Server2],[Server3], and [Server4] are provided for other time-servers.3) Check that the SNTP is shown under the ActivSyncSrc, as shown in Figure 4.7-4.4) Check to see that the time zone and the DST are set correctly (see 4.7.4 and 4.7.5).Clock10:00 1/2[Time] +2012-11-21 10:00:05[Format]YYYY-MM-DD HH:mm:ss[ActiveSyncSrc] >SNTP Check “SNTP” being shown under ActiveSyncSrc.Figure 4.7-4 Time setting for SNTPTable 4.7-1 Settings for the SNTP synchronizationSetting item Range Contents Setting exampleTimeSyncSrc SNTP / BI / MODBUS / IRIG-B / IEC103 Selection of sync method SNTPSNTP Off /On Operation of SNTP ()OnServer1 000.000.000.000–255.255.255.255 Setting for Time server 1 197.1.23.11Server2 000.000.000.000–255.255.255.255 Setting for Time server 2 000.000.000.000Server3 000.000.000.000–255.255.255.255 Setting for Time server 3 000.000.000.000Server4 000.000.000.000–255.255.255.255 Setting for Time server 4 000.000.000.000
