Operation principle
Upon receiving an analog signal at its input, IEC61850 generic communication I/O
functions (MVGGIO) will give the instantaneous value of the signal and the range, as
output values. In the same time, it will send over IEC 61850-8-1 the value, to other
IEC 61850 clients in the substation.

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 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-high limit or above high limit. The output
signals can be used as conditions in the configurable logic or for alarming purpose.
