Duplex
Half duplex: One channel is available for alternating exchange of information.
Full duplex: Two channels are available for simultaneous exchange of information in both
directions.
Ethernet
Ethernet is an international standard technology for local area networks (LAN) based on
frames. It defines types of cables and signaling for the physical layer and packet formats and
protocols for media access control.
GSD file
As a Generic Station Description, this file contains all properties of a PROFINET device that
are necessary for its configuration in XML format.
I-device
The "I-device" (intelligent IO device) functionality of a CPU facilitates data exchange with an
IO controller, for example, as intelligent preprocessing unit of sub-processes. In its role as an
IO device, the I-device is accordingly integrated into a "higher-level" IO controller.
Industrial Ethernet
Industrial Ethernet is a guideline for installing an Ethernet in an industrial environment. The
biggest difference from standard Ethernet is the mechanical current carrying capacity and
noise immunity of the individual components.
Interrupt
An interrupt is an event that causes the operating system of an S7-CPU to automatically call
an assigned organization block (interrupt OB) in which the user can program the desired
reaction.
