13.9.3 Signals13.9.3.1 Input signalsThe Event list logs the same binary input signals as configured for the Disturbancereport function.13.9.4 Operation principleWhen a binary signal, connected to the disturbance report function, changes status,the event list function stores input name, status and time in the event list inchronological order. The list can contain up to 1000 events from both internal logicsignals and binary input channels. If the list is full, the oldest event is overwrittenwhen a new event arrives.The list can be configured to show oldest or newest events first with a setting onthe local HMI.The event list function runs continuously, in contrast to the event recorder function,which is only active during a disturbance.The name of the binary input signal that appears in the event recording is the user-defined name assigned when the IED is configured. The same name is used in thedisturbance recorder function , indications and the event recorder function .The event list is stored and managed separate from the disturbance report information .13.9.5 Technical dataTable 330:DRPRDRE technical dataFunction ValueBuffer capacity Maximum number of events in the list 1000Resolution 1 msAccuracy Depending on timesynchronizing13.10 Trip value recorder13.10.1 FunctionalityInformation about the pre-fault and fault values for currents and voltages are vitalfor the disturbance evaluation.Section 13 1MRK 502 034-UEN -Monitoring416Technical Manual
