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 via a field bus with the CPU (I/O) controller and prepared the data for the/from the
I/O modules.
Parameter assignment
Parameter assignment is the transfer of parameters from the IO controller to the IO device.

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.
