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 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.
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 reassembly
through the data link layer.
2. Ingression protection, according to IEC standard
