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 60529
