Industrial Ethernet is the word for an identical infrastructure within local area networks, but with a modified protocol. The protocol is not the standard Ethernet one. This is how networks exceed the office communication and integrate industrial field devices by using the same hardware platform. At the same time process security is improved by the modified protocols and your productivity stays high. There are different protocols for industrial ethernet standard, established are such as Profinet, Ether-CAT, EthernetIP, Powerlink and Sercos III with runtimes down to 100?s. Therefore protocols are capable of real-time applications and thus motion control. This standard has established in the market more and more. There are 2 pin configuration defined by the standard A and B, B is used more often. Whenever it does not come to Gigabit networks, the use of the pins 1, 2, 3 and 6 is sufficient.
