generated by both internal logical signals and binary input channels. The internalsignals are time-tagged in the main processor module, while the binary input channelsare time-tagged directly in each I/O module. The events are collected during the totalrecording time (pre-, post-fault and limit time), and are stored in the disturbance reportflash memory at the end of each recording.In case of overlapping recordings, due to PostRetrig = On and a new trig signalappears during post-fault time, events will be saved in both recording files.The name of the binary input signal that appears in the event recording is the user-defined name assigned when configuring the IED. The same name is used in thedisturbance recorder function , indications and event recorder function.The event record is stored as a part of the disturbance report information and managedvia the local HMI or PCM600.Events can not be read from the IED if more than one user is accessingthe IED simultaneously.12.6.5 Technical dataTable 392:DRPRDRE technical dataFunction ValueBuffer capacity Maximum number of events in disturbancereport150Maximum number of disturbance reports 100Resolution 1 msAccuracy Depending on timesynchronizing12.7 Event list12.7.1 FunctionalityContinuous event-logging is useful for monitoring the system from an overviewperspective and is a complement to specific disturbance recorder functions.The event list logs all binary input signals connected to the Disturbance recorderfunction. The list may contain up to 1000 time-tagged events stored in a ring-buffer.12.7.2 Function blockThe Event list has no function block of it’s own.Section 12 1MRK 511 287-UEN AMonitoring458Technical manual
