14.15.6 Monitored dataPID-6928-MONITOREDDATA v1Table 335:INTCOMP Monitored dataName Type Values (Range) Unit DescriptionINEQUAL BOOLEAN - - Input value is equal tothe reference valueINHIGH BOOLEAN - - Input value is higherthan the reference valueINLOW BOOLEAN - - Input value is lower thanthe reference value14.15.7 Operation principle GUID-E9C1B863-ACA7-45C0-91F1-A51FE38755FE v2The comparison can be done in two ways,• Between 2 inputs, INPUT and REF• Between INPUT and the value set by the user SetValue.The selection of reference value for comparison can be done through settingRefSource. If RefSource is selected as Input REF then the reference value forcomparison is taken from second input signal (REF). If RefSource is selected as SetValue then the reference value for comparison is taken from setting (SetValue).The comparison can be done either between absolute values or signed values and itdepends on the setting EnaAbs. If EnaAbs is selected as Absolute then both inputand reference value is converted into absolute values and comparison is done. IfEnaAbs is selected as Signed then the comparison is done without any conversion.The function has three state outputs high, low and equal to condition. It will checkthe following condition and give corresponding outputs.• If the input is above the reference value then INHIGH is set HIGH• If the input is below the reference value then INLOW is set HIGH• If the input is equal to reference value then INEQUAL is set HIGH1MRK 505 394-UEN A Section 14LogicLine differential protection RED650 2.2 IEC 491Technical manual
