14.13.2 FunctionalityThe current and voltage measurements functions (CVMMXN, CMMXU, VMMXUand VNMMXU), current and voltage sequence measurement functions (CMSQI andVMSQI) and IEC 61850 generic communication I/O functions (MVGGIO) areprovided with measurement supervision functionality. All measured values can besupervised with four settable limits: low-low limit, low limit, high limit and high-highlimit. The measure value expander block MVEXP has been introduced to enabletranslating the integer output signal from the measuring functions to 5 binary signals:below low-low limit, below low limit, normal, above high limit or above high-highlimit. The output signals can be used as conditions in the configurable logic or foralarming purpose.14.13.3 Function blockMVEXPRANGE* HIGHHIGHHIGHNORMALLOWLOWLOWIEC09000215-1-en.vsdIEC09000215 V1 ENFigure 259: MVEXP function block14.13.4 SignalsTable 411:MVEXP Input signalsName Type Default DescriptionRANGE INTEGER 0 Measured value rangeTable 412:MVEXP Output signalsName Type DescriptionHIGHHIGH BOOLEAN Measured value is above high-high limitHIGH BOOLEAN Measured value is between high and high-high limitNORMAL BOOLEAN Measured value is between high and low limitLOW BOOLEAN Measured value is between low and low-low limitLOWLOW BOOLEAN Measured value is below low-low limit14.13.5 SettingsThe function does not have any parameters available in Local HMI or Protection andControl IED Manager (PCM600).Section 14 1MRK 502 048-UEN AMonitoring550Technical manual
