There are 2 versions of PRP: PRP-0 and its successor PRP-1. Siemens implements PRP-1.
Parameterization
Comprehensive term for all setting work on the device. You can parameterize the protection functions with
DIGSI 5 or sometimes also directly on the device.
Parameter set
The parameter set is the entirety of all parameters that can be set for a SIPROTEC device.
Participant address
A participant address consists of the name of the participant, the international dialing code, the local dialing
code and the participant-specific telephone number.

PROFIBUS
PROcess Feld BUS, German Process and Fieldbus standard (EN 50170). The standard specifies the functional,
electrical and mechanical characteristics for a bit-serial fieldbus.
PROFIBUS Address
A unique PROFIBUS address must be assigned to each SIPROTEC device within a PROFIBUS network. A total of
254 PROFIBUS addresses per PROFIBUS network are available.
Profile_ID
A Profile_ID in combination with an API uniquely identifies the access and the behavior of an application.
PROFINET IO
PROFINET is an open Industrial Ethernet Standard from PROFIBUS for the automation.
Programmable Logic
The programmable logic is a function in Siemens devices or station controllers, enabling user-specific func-
tionality in the form of a program. This logic component can be programmed by various methods: CFC (=
Continuous Function Chart) is one of these. SFC (Sequential Function Chart) and ST (Structured Text) are
others.
Programmable Logic Controller
Programmable logic controllers (PLC) are electronic controllers whose function is saved as a program in the
control unit. The construction and wiring of the device do not therefore depend on the function of the control.
The programmable logic controller has the structure of a computer; it consists of CPU with memory, installa-
tion/extension groups (for example, DI, AI, CO, CR), power supply (PS) and rack (with bus system). The periph-
erals and programming language are oriented towards the circumstances of the control system.
Programmable Logic Module
Modules are parts of the user program delimited by their function, structure and intended use.
