Glossary
Functional ground
The functional ground is a low-impedance current path between electric circuits and ground.
It is not intended as a protective measure but rather, for example, for improvement of
interference immunity.
Ground
Conductive ground whose electrical potential can be set to zero at any point.
All interconnected, inactive parts of a piece of equipment that cannot accept any dangerous
contact voltage, even in the event of a fault.

Grounding
Grounding means connecting an electrically conductive part to a grounding electrode by
means of a grounding system.
GSD file
The Generic Station Description file contains all properties of a PROFINET or PROFIBUS device
that are necessary for its configuration.
Handling system
A device that manages the flow of material from or to a workstation, in other words that is
used for handling.
Hardware interrupt
You can find relevant information in the entry "Interrupt, process".
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 reviewing the system
configuration and locating hardware changes.
