GSD file
The properties of a PROFINET device are described in a GSD (Generic Station Description)
file, which contains all required information for the configuration.
As with PROFIBUS, you can link a PROFINET device in STEP 7 by means of a GSD file.
In PROFINET IO, the GSD file is in XML format. The structure corresponds to ISO 15734,
the worldwide standard for device descriptions.
Industrial Ethernet
Industrial Ethernet (previously SINEC H1) is a technology that allows data to be transferred
fail-safe in an industrial environment.
Standard Ethernet components can be used since PROFINET is an open system. However,
we recommend setting up PROFINET as Industrial Ethernet.
Internal lightning protection
Shielding of buildings, rooms or devices Corresponds with lightning protection zone 1, 2 or 3.
Isochronous real-time communication
Synchronized transmission method for the cyclic exchange of IRT data between PROFINET
devices
A reserved bandwidth is available within the send cycle for IRT IO data. The reserved
bandwidth guarantees that IRT data can also be transferred at reserved, synchronized
intervals while other, higher network loads are active (for example TCP/IP communication, or
additional real-time communication).
MAC address
Every PROFINET device is assigned a worldwide unique device identification before it
leaves the factory. This 6-Byte long device identification is the MAC address.
The MAC address is divided into:
● 3-Byte manufacturer identification and
● 3-Byte device identification (consecutive number)
The MAC address is generally shown on the front of the device, for example: 08-00-06-6B-
80-C0
Non-isolated
The reference potentials of the control and load circuit of non-isolated I/O modules are
electrically interconnected.
Parameter assignment
The term parameterization denotes the transfer of parameters from the IO Controller to the
IO Device.
