Event function EVENT M11880-82 v6The Event function (EVENT) sends time-tagged events to the station level (forexample, operator workplace) over the station bus. On the station level, events arepresented in an event list. Events can be created from both internal logical signalsand binary input channels. All the internal signals are time tagged in the mainprocessing module, while the binary input channels are time tagged directly oneach I/O module. Events are produced according to a set of event masks. Thesemasks are treated commonly for both LON and SPA channels.Two special signals for event registration purposes are available in the IED:Terminal Restarted (0E50) and Event buffer overflow (0E51).The status and event codes for the EVENT function are found in Table 498.Table 498:Status and event codesSingle indication1) Double indicationEvent block Status Set event ReseteventIntermediate 00Closed 10 Open 01 Undefined11EVENT:1Input 1Input 2Input 3Input 4Input 5Input 6Input 7Input 8Input 9Input 10Input 11Input 12Input 13Input 14Input 15Input 1622O122O222O322O422O522O622O722O822O922O1022O1122O1222O1322O1422O1522O1622E3322E3522E3722E3922E4122E4322E4522E4722E4922E5122E5322E5522E5722E5922E6122E6322E3222E3422E3622E3822E4022E4222E4422E4622E4822E5022E5222E5422E5622E5822E6022E6222E022E422E822E1222E1622E2022E2422E28--------22E122E522E922E1322E1722E2122E2522E29--------22E222E622E1022E1422E1822E2222E2622E30--------22E322E722E1122E1522E1922E2322E2722E31--------EVENT:2EVENT:3---EVENT:20230..240..---410..23E..24E..---41E..23E..24E..---41E..23E..24E..---41E..23E..23E..---41E..23E..24E..---41E..23E..24E..---41E..These values are only applicable if the event mask is masked ≠ OFF.Connection of signals as events M11880-311 v5Signals coming from different protection and control functions and sent as eventsto the station level over the SPA-bus (or LON-bus), are connected to the EVENTfunction block as specified in Figure 335.1MRK 505 394-UEN A Section 18Station communicationLine differential protection RED650 2.2 IEC 703Technical manual
