1)
The instances of a protection function represent the number of identical function blocks available in a standard configuration. By setting the
application specific parameters of an instance, a protection function stage can be established.
2)
Multi-purpose protection is used for, for example, RTD/mA based protection
3)
Available in IED and SMT but not connected to anything in logic.
4)
Io selectable by parameter, Io measured as default
5)
Io calculated is always used
6)
Uo selectable by a parameter, Uo measured as default
7)
IoB measured and 3IB are always used
8)
IoB measured is always used
9)
