Bay Level Functions
Functions that pertain to a bay. The bay level represents an additional layer of
control below the overall substation level. These functions communicate via the
logical interface 3 within the bay level and via the logical interfaces 4 and 5 to the
process level, i.e. with any kind of remote I/Os or intelligent sensors and
actuators. Interfaces 4 and 5 may be hardwired also but hardwired interfaces are
beyond the scope of the IEC-61850 series.
