Implementation of Industrial Ethernet
By Christian Schlegel, IXXAT Automation GmbH
Today, the industrial automation market for Ethernet-based communication is increasing in demand. As with classical field busses, several protocol standards are available for Industrial Ethernet, which have to be supported by device manufacturers. Since these different Ethernet standards vary in their hardware and software requirements, a specific protocol solution for their integration into a device is required.
Despite the efforts of IAONA to find a common solution for industrial communication over Ethernet, disparate protocols emerged that were sponsored and promoted by a number of classic field bus suppliers. Eleven concepts to achieve Ethernet relevant for industrial communication are currently standardized within IEC 61158. Similar to the so-called “field bus wars” in the eighties, in the end, some of the eleven Industrial Ethernet solutions will be accepted in the market.
