When several occurrences of the same function are available
in the IED, they are referred to as instances of that function.
One instance of a function is identical to another of the same
kind but has a different number in the IED user interfaces.
The word "instance" is sometimes defined as an item of
information that is representative of a type. In the same way
an instance of a function in the IED is representative of a type
of function.
1. Internet protocol. The network layer for the TCP/IP
protocol suite widely used on Ethernet networks. IP is a
connectionless, best-effort packet-switching protocol. It
provides packet routing, fragmentation and reassembly
through the data link layer.
