Instance 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 will have 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.
IP 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 re-assembly
through the data link layer.
