• Should the function record faults only for the protected object or cover more?• How long is the longest expected fault clearing time?• Is it necessary to include reclosure in the recording or should a persistent faultgenerate a second recording (PostRetrig)?Minimize the number of recordings:• Binary signals: Use only relevant signals to start the recording that is,protection trip, carrier receive and/or start signals.• Analog signals: The level triggering should be used with great care, sinceunfortunate settings will cause enormously number of recordings. Ifnevertheless analog input triggering is used, chose settings by a sufficientmargin from normal operation values. Phase voltages are not recommended fortrigging.There is a risk of flash wear out if the disturbance report triggerstoo often.Remember that values of parameters set elsewhere are linked to the information ona report. Such parameters are, for example, station and object identifiers, CT andVT ratios.10.7 Logical signal status report BINSTATREPGUID-E7A2DB38-DD96-4296-B3D5-EB7FBE77CE07 v210.7.1 Identification GUID-E0247779-27A2-4E6C-A6DD-D4C31516CA5C v3Function description IEC 61850identificationIEC 60617identificationANSI/IEEE C37.2device numberLogical signal status report BINSTATREP - -10.7.2 Application GUID-F9D225B1-68F7-4D15-AA89-C9211B450D19 v3The Logical signal status report (BINSTATREP) function makes it possible to pollsignals from various other function blocks.BINSTATREP has 16 inputs and 16 outputs. The output status follows the inputsand can be read from the local HMI or via SPA communication.When an input is set, the respective output is set for a user defined time. If theinput signal remains set for a longer period, the output will remain set until theinput signal resets.Section 10 1MRK 511 423-UEN AMonitoring218 Bay control REC650 2.2 IECApplication manual
