Integer to Boolean 16 conversion with logic noderepresentation ITBGAPC SEMOD158421-5 v9Integer to boolean conversion with logic node representationfunction (ITBGAPC) is used to transform an integer which istransmitted over IEC 61850 and received by the function to16 boolean (logic) output signals.Comparator for integer inputs INTCOMPGUID-A93564FA-0017-4939-A9C1-095DA0FD9832 v1The function gives the possibility to monitor the level ofinteger values in the system relative to each other or to afixed value. It is a basic arithmetic function that can be usedfor monitoring, supervision, interlocking and other logics.Comparator for real inputs REALCOMPGUID-E17A88D7-D095-4F36-9CD5-64EBFD2A1DEA v1The function gives the possibility to monitor the level of realvalue signals in the system relative to each other or to a fixedvalue. It is a basic arithmetic function that can be used formonitoring, supervision, interlocking and other logics.11. MonitoringMeasurements CVMMXN, CMMXU, VNMMXU, VMMXU,CMSQI, VMSQI M12024-3 v9The measurement functions are used to get on-lineinformation from the IED. These service values make itpossible to display on-line information on the local HMI andon the substation automation system about:• measured voltages, currents, frequency, active, reactiveand apparent power and power factor• measured analog values from merging units• primary phasors• positive, negative and zero sequence currents andvoltages• mA, input currents• pulse countersDisturbance report DRPRDRE M12153-3 v13Complete and reliable information about disturbances in theprimary and/or in the secondary system together withcontinuous event-logging is accomplished by the disturbancereport functionality.Disturbance report (DRPRDRE), always included in the IED,acquires sampled data of all selected analog input and binarysignals connected to the function block with a maximum of40 analog and 352 binary signals.The Disturbance report functionality is a common name forseveral functions:• Event list• Indications• Event recorder• Trip value recorder• Disturbance recorder• Fault locator• Settings informationThe Disturbance report function is characterized by greatflexibility regarding configuration, starting conditions,recording times, and large storage capacity.A disturbance is defined as an activation of an input to theAnRADR or BnRBDR function blocks, which are set to triggerthe disturbance recorder. All connected signals from start ofpre-fault time to the end of post-fault time will be included inthe recording. Disturbance record will have visible settingsfrom all function instances that are configured in theapplication configuration tool.Every disturbance report recording is saved in the IED in thestandard Comtrade format as a reader file HDR, aconfiguration file CFG, and a data file DAT. The same appliesto all events, which are continuously saved in a ring-buffer.The local HMI is used to get information about the recordings.The disturbance report files can be uploaded to PCM600 forfurther analysis using the disturbance handling tool.Event list DRPRDRE M12412-6 v8Continuous event-logging is useful for monitoring the systemfrom an overview perspective and is a complement to specificdisturbance recorder functions.The event list logs all binary input signals connected to theDisturbance recorder function. The list may contain up to1000 time-tagged events stored in a ring-buffer.Indications DRPRDRE M12030-3 v6To get fast, condensed and reliable information aboutdisturbances in the primary and/or in the secondary system itis important to know, for example binary signals that havechanged status during a disturbance. This information is usedin the short perspective to get information via the local HMI ina straightforward way.There are three LEDs on the local HMI (green, yellow andred), which will display status information about the IED andthe Disturbance recorder function (triggered).The Indication list function shows all selected binary inputsignals connected to the Disturbance recorder function thathave changed status during a disturbance.Event recorder DRPRDRE M12033-3 v8Quick, complete and reliable information about disturbancesin the primary and/or in the secondary system is vital, forexample, time-tagged events logged during disturbances.This information is used for different purposes in the shortterm (for example corrective actions) and in the long term (forexample functional analysis).1MRK 506 384-BEN ALine distance protection REL650 2.2Product version: 2.2.1ABB 23
