Ground
Conductive earth whose electrical potential can be set equal 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.

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.
IO-Link
IO-Link is a point-to-point connection to conventional and intelligent sensors/actuators by
unshielded standard cables in proven 3-wire technology. IO-Link is downward compatible to
all DI/DQ sensors/actuators. Switching status channel and data channel are designed in
proven 24 V DC technology.
