Glossary
Ground
A part of the ground, which is considered conductive and whose electrical potential is usually
assumed to be zero, is outside the zero point of influence of a grounding arrangement.
All electrically conductive, interconnected, inactive parts of a piece of equipment that cannot
accept any dangerous contact voltage, even in the event of a fault.
GSD file
As a generic station description, this file in XML format has all the properties of a PROFINET or
PROFIBUS device that are required for its configuration.
I/O modules
All modules that can be operated with a CPU or an interface module.
Identification data
Information that is saved in modules and that supports the user in checking the plant
configuration and locating hardware changes.
Interface module
Module in the distributed I/O system. The interface module connects the distributed I/O
system to the CPU (IO controller) via fieldbus and processes the data for and from I/O devices.
Parameter assignment
Parameter assignment is the transfer of parameters from the IO controller to the IO device.
PELV
Protective Extra Low Voltage = grounded protective extra-low voltage
PROFINET
PROcess FIeld NETwork, open Industrial Ethernet standard, which continues PROFIBUS and
Industrial Ethernet. A cross-manufacturer communication, automation and engineering
model, defined as an automation standard by PROFIBUS International e.V.
PROFINET IO controller
Device used to address connected I/O devices (for example, distributed I/O systems). This
means that: The IO controller exchanges input and output signals with assigned IO devices.
The IO controller often corresponds with the CPU in which the automation program is
running.
