USING THE IEC 61850 CONFIGURATOR
4-30
Within 3 Series relays there are 32 Virtual Inputs. The status of each of these 32 Virtual
Inputs is automatically mapped into GGIO3 indication 1 through 32 within the stVal bit. In
other words, each stVal bit within each indication, reflects the status of the corresponding
Virtual Input. In addition to the individual digital status, each indication area contains a
time stamp for the last change and an indication of the quality of the data. Within the
EnerVista 3 Series Setup software, the user can drag and drop the stVal bit or other digital
or analog values, from resident logical nodes into the GOOSE message in order to build the
GOOSE message that this relay will eventually transmit.
