12.10.7 Operation principle
Upon receiving signals at its inputs, IEC 61850 generic communication I/O functions
16 inputs (SP16GGIO) function will send the signals over IEC 61850-8-1 to the
equipment or system that requests this signals. To be able to get the signal, one must
use other tools, described in the Engineering manual and define which function block
in which equipment or system should receive this information.
There are also 16 output signals that show the input status for each input as well as an
OR type output combined for all 16 input signals. These output signals are handled in
PST.

12.11.2 Functionality
IEC61850 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.
