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 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.
