Ethernet currently has a market share of over 80% with a ten- dency to rise further, thus placing it in pole position in the global LAN landscape. Ethernet offers important characteristics that can give you significant advantages for your application:

7Fast commissioning through simple connections

7High flexibility since existing networks can be extended with- out any adverse effects

7High availability thanks to redundant network topologies

7Almost unlimited communications performance because scal- able performance is available through switching technology if required

7Networking of different application areas such as office and production areas

7Investment protection through continuous and compatible fur- ther development

7Plant-wide clock system permits exact assignment of events within the complete plant

Ethernet technology for industrial environment

With Industrial Ethernet, SIMATIC NET expands the Ethernet technology by special components and capabilities for use in in- dustrial environments:

7Network components for tough industrial environments

7Fast local assembly using the FastConnect cabling system with RJ45 technology

7Failsafe networks with fast switchover to redundant system (≤ 300 ms)

7Continuous monitoring of network components through a sim-

ple yet effective signaling concept	9
7 Future-oriented network components with the SCALANCE X

Ethernet product family

Industrial Ethernet, connection examples

The plant bus and the OS-LAN (terminal bus) for multi-user systems with client/server architecture are implemented with Industrial Ethernet, a powerful area and cell network for indus- trial applications in line with the international IEEE 802.3 stan- dard (Ethernet). Bus structures with optical rings are particularly suitable for this because of their high noise immunity and high availability.

In medium-sized and large plants characterized by high requirements, SIMATIC PCS 7 applies modern Gigabit and FastEthernet technology. This combines the high reliability of op- tical rings with the scalable performance of switching technol- ogy and high transmission rates up to 1 Gbit/s.
