In the same time, it will send over IEC 61850-8-1 the value, to other IEC61850 clients in the substation.14.13 Measured value expander block MVEXP14.13.1 IdentificationFunction description IEC 61850identificationIEC 60617identificationANSI/IEEE C37.2device numberMeasured value expander block MVEXP - -14.13.2 FunctionalityThe current and voltage measurements functions (CVMMXN, CMMXU, VMMXU andVNMMXU), current and voltage sequence measurement functions (CMSQI and VMSQI)and IEC 61850 generic communication I/O functions (MVGGIO) are provided withmeasurement supervision functionality. All measured values can be supervised with foursettable limits: low-low limit, low limit, high limit and high-high limit. The measure valueexpander block MVEXP has been introduced to enable translating the integer outputsignal from the measuring functions to 5 binary signals: below low-low limit, below lowlimit, normal, above high limit or above high-high limit. The output signals can be usedas conditions in the configurable logic or for alarming purpose.1MRK 502 048-UUS A Section 14Monitoring591Technical manual
