Operation principle

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

Application

IEC 61850 generic communication I/O functions (MVGGIO) function is used to send
the instantaneous value of an analog signal to other systems or equipment in the
substation. It can also be used inside the same IED, to attach a RANGE aspect to an
analog value and to permit measurement supervision on that value.
