Industrial Ethernet in the communications landscape


Ethernet presently has a market share of over 80 % with a rising trend, thus placing it in the pole position in the LAN landscape worldwide. Ethernet offers important characteristics that can give you significant advantages for your application:

  • Investment protection through continuous compatible further development
  • Network components for use in harsh industrial environments
  • Fast assembly and start-up thanks to the simplest connection method.
  • High availability of the networks due to ring redundancy and redundant power supply
  • Continuous monitoring of network components through a simple and effective signaling concept
  • Almost unlimited communications performance, since scalable performance is available through switching technology if required
  • Networking of different application areas such as office and production areas.
  • Data reservation in the case of Industrial Wireless LAN (IWLAN)
  • Rapid roaming for Industrial Wireless LAN (IWLAN) for high-speed forwarding of mobile stations between various access points
  • In Industrial Ethernet, plant-wide time synchronization is possible. This means that events can be arranged accurately in the order of occurrence throughout the plant.

Industrial Ethernet serves as the basis for use of Component based Automation which is based on the PROFINET standard of PROFINET International (PNO).


SIMATIC NET relies on this proven technology. Siemens has established well over two million connections worldwide in tough industrial environments subject to electromagnetic interference.

With the aid of switching technology, ranges are almost unlimited. In addition, Industrial Ethernet offers the option of wireless communication that can be seamlessly integrated into the network structure. This means that information is available anywhere at any time and mobile access is made possible through Industrial Wireless LAN to the Intranet/Internet .

Industrial Ethernet uses data communication to exchange data between programmable controllers or between a programmable controller and intelligent partners (e.g. PCs).

Industrial Ethernet enables high-performance communication networks to be created in extensive linear, ring or star configurations.
