System overview Ethernet und TCP/IP

Ethernet is one of the network protocols that is available universally and independently for all common operating systems and also supports large numbers of devices and expansions. In cooperation with TCP/IP, therefore, Ethernet is the dominating standard in the office world. The low costs of standard components are also contributing to the further spreading of Ethernet in the world of automation. For example, the operating access to many automation devices via an Internet browser, which is common today, only became possible through the universal use of TCP/IP. The advantages of Ethernet, such as high data transmission rates, easy methods of integration into existing networks, and a wide range of services and interfaces are also found in the Beckhoff Ethernet products.
