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.
