12.13.2 Functionality
The current and voltage measurements functions (CVMMXN, CMMXU, VMMXU
and VNMMXU), current and voltage sequence measurement functions (CMSQI and
VMSQI) and IEC 61850 generic communication I/O functions (MVGGIO) are
provided with measurement supervision functionality. All measured values can be
supervised with four settable limits: low-low limit, low limit, high limit and high-high
limit. The measure value expander block MVEXP has been introduced to enable
translating 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-high
limit. The output signals can be used as conditions in the configurable logic or for
alarming purpose.
