Section 8 1MAC309294-MB FRecording functions418 RER620Technical Manual8.1.2.7 Exclusion modeExclusion mode is on, when the value set with the Exclusion time parameter is higher thanzero. During the exclusion mode, new triggerings are ignored if the triggering reason is thesame as in the previous recording. The Exclusion time parameter controls how long theexclusion of triggerings of same type is active after a triggering. The exclusion mode onlyapplies to the analog and binary channel triggerings, not to periodic and manualtriggerings.When the value set with the Exclusion time parameter is zero, the exclusion mode isdisabled and there are no restrictions on the triggering types of the successive recordings.The exclusion time setting is global for all inputs, but there is an individual counter foreach analog and binary channel of the digital fault recorder, counting the remainingexclusion time. The user can monitor the remaining exclusion time with the Exclusion timerem parameter of the corresponding analog or binary channel. The Exclusion time remparameter counts downwards.8.1.3 ConfigurationThe user can configure the digital fault recorder with the PCM600 tool or any toolsupporting the IEC 61850 standard.The user can enable or disable the digital fault recorder with the Operation parameterunder the Configuration/Digital fault recorder/General menu.One analog signal type of the relay can be mapped to each of the analog channels of thedigital fault recorder. The mapping is done with the Channel selection parameter of thecorresponding analog channel. The name of the analog channel is user-configurable. Theuser can modify it by writing the new name to the Channel id text parameter of thecorresponding analog channel.Any external or internal digital signal of the relay which can be dynamically mapped canbe connected to the binary channels of the digital fault recorder. These signals can be, forexample, the start and trip signals from protection function blocks or the external binaryinputs of the relay. The connection is made with dynamic mapping to the binary channelof the digital fault recorder using, for example, SMT of PCM600. It is also possible toconnect several digital signals to one binary channel of the digital fault recorder. In thatcase, the signals can be combined with logical functions, for example AND and OR. Theuser can configure the name of the binary channel and modify it by writing the new nameto the Channel id text parameter of the corresponding binary channel.Note that the Channel id text parameter is used in COMTRADE configuration files as achannel identifier.The recording always contains all binary channels of the digital fault recorder. If one ofthe binary channels is disabled, the recorded state of the channel is continuously FALSEand the state changes of the corresponding channel are not recorded. The correspondingchannel name for disabled binary channels in the COMTRADE configuration file isUnused BI.To enable or disable a binary channel of the digital fault recorder, the user can set theOperation parameter of the corresponding binary channel to the values “on” or “off”.
