Trip matrix logic TMAGGIOTrip matrix logic TMAGGIO function is used to route tripsignals and other logical output signals to different outputcontacts on the IED.TMAGGIO output signals and the physical outputs allows theuser to adapt the signals to the physical tripping outputsaccording to the specific application needs.Configurable logic blocksA number of logic blocks and timers are available for the userto adapt the configuration to the specific application needs.• OR function block.• INVERTER function blocks that inverts the input signal.• PULSETIMER function block can be used, for example, forpulse extensions or limiting of operation of outputs, settablepulse time.• GATE function block is used for whether or not a signalshould be able to pass from the input to the output.• XOR function block.• LOOPDELAY function block used to delay the output signalone execution cycle.• TIMERSET function has pick-up and drop-out delayedoutputs related to the input signal. The timer has a settabletime delay.• AND function block.• SRMEMORY function block is a flip-flop that can set orreset an output from two inputs respectively. Each blockhas two outputs where one is inverted. The memory settingcontrols if the block's output should reset or return to thestate it was, after a power interruption. Set input haspriority.• RSMEMORY function block is a flip-flop that can reset orset an output from two inputs respectively. Each block hastwo outputs where one is inverted. The memory settingcontrols if the block's output should reset or return to thestate it was, after a power interruption. RESET input haspriority.Extension logic packageThe logic extension block package includes additional tripmatrix logic and configurable logic blocks.Fixed signal function blockThe Fixed signals function (FXDSIGN) generates a number ofpre-set (fixed) signals that can be used in the configuration ofan IED, either for forcing the unused inputs in other functionblocks to a certain level/value, or for creating certain logic.12. MonitoringMeasurements CVMMXN, CMMXU, VNMMXU, VMMXU,CMSQI, VMSQIThe 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• primary and secondary phasors• positive, negative and zero sequence currents andvoltages• mA, input currents• pulse countersSupervision of mA input signalsThe main purpose of the function is to measure and processsignals from different measuring transducers. Many devicesused in process control represent various parameters such asfrequency, temperature and DC battery voltage as low currentvalues, usually in the range 4-20 mA or 0-20 mA.Alarm limits can be set and used as triggers, e.g. to generatetrip or alarm signals.The function requires that the IED is equipped with the mAinput module.Event counter CNTGGIOEvent counter (CNTGGIO) has six counters which are used forstoring the number of times each counter input has beenactivated.Disturbance report DRPRDREComplete 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 96 binary signals.The Disturbance report functionality is a common name forseveral functions:• Event list• Indications• Event recorder• Trip value recorder• Disturbance recorder• Fault locatorThe Disturbance report function is characterized by greatflexibility regarding configuration, starting conditions,recording times, and large storage capacity.Bay control REC670 1MRK511232-BEN EPre-configuredProduct version: 1.216 ABB
