Ethernet

The Industrial Ethernet is a high- performance network that conforms to IEE 802.3 (ETHERNET). The highly successful 10Mbit/s technology, which has been used for over a decade, and the new 100Mbit/s technology (Fast Ethernet to IEEE 802.3u) in conjunction with Switching Full Duplex and Autosensing enable the required network performance to be adapted to different requirements. The appropriate data rates are selected as required because complete compatibility enables the technology to be implemented on a step-by-step basis.

Used in 80% of networks, Ethernet is currently the best of its kind in LAN environments.

Ethernet does not function according to a master-slave principle. All the stations have equal priority on the bus, which means that any station can be the sender or receiver. A sender can only send on the bus if no other station is sending at that time. This is due to the fact that the stations are always "listening in" to find out whether any messages are being sent to them or any senders are currently active. If a sender has started sending, it checks that the message it has sent is not corrupt. If the message is not changed, the send operation continues.

If the sender detects that its data is corrupt, another sender must have already started sending data. In this case, both senders abort their respective send operations.

After a random time has elapsed, the sender restarts the send operation. This is known as CSMA/CD and, as a "random" access procedure, does not guarantee a response within a certain time frame. This largely depends on the bus load, which means that real- time applications cannot yet be implemented with Ethernet.
