The latest development in the IEC 61850
standard was the inclusion of the
PRP/HSR protocol in 2010. PRP/HSR
(parallel redundancy protocol/high-
availability seamless redundancy)
specifies how to use two Ethernet
networks to ensure seamless failover if
one of the redundant networks fails.

In 2005, the IEC 61850 standard was
greatly improved by defining a Process
Bus to connect the Process Level with
the Bay Level.

The release of the IEC 61850 Station
Bus protocol in the 1980’s was a big first
step forward on the way to implementing
a substation-wide all-purpose network.
In the 1960’s a conventional
substation was rather bulky, with
copper or fiber wiring used to hard-
wire one device to another.
