An IEC61850/IEC61850 PACiS GTW can be redunded. In this case both PACiS GTWs have
exactly the same configuration.
The main features of the management of this redundancy are:
•
both PACiS GTWs performs the same acquisition on the lower network and send the
same information to the upper network
•
one PACiS GTW is master at one time: an IEC object ( RedSt : Redundancy status) is
set for a master PACiS GTW and reset for a slave PACiS GTW. The PACiS GTWs
are servers of this object.
•
An IEC61850 client on the upper network takes only into account information coming
from PACiS GTW whose the redSt is set. It sends controls only to this PACiS GTW.
•
In case of failure of the master PACiS GTW, the other one becomes the new master
PACiS GTW.
•
In case of natwork failure ( upper network or lower network, the current master PACiS
GTW goes in Maintenance mode and the other PACiS GTW becomes the new master
