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. At the
same time, it will send over IEC 61850-8-1 the value, to other IEC 61850 clients in the substation.
The principles of zero-point clamping, range supervision, and value reporting are explained in
Section
settings.
