The production landscape keeps changing—it is networked, and there is increasing communication among different company divisions or even across company boundaries. Thomas Brand*, Analog Devices, explains that there is a lively exchange of countless, diverse data between all parties involved in a company, whether human or machine: “Where previously only individual machines were connected to each other, in the future networking will be omnipresent—from individual sensors and actuators to machines and complete systems. All production participants are connected thanks to the transition to digitisation driven by Industry 4.0 or the Industrial Internet of Things (IIoT). Ethernet and industrial Ethernet are increasingly emerging as essential communication standards since they provide decisive advantages over previous fieldbuses such as greater transmission rates and higher reliability.” In addition, industrial Ethernet offers the possibility to bring the entire communications technology within a network (from the sensor to the cloud) to one unique standard. It complements the classical Ethernet with real-time functions and determinism. Brand comments: “We speak of time sensitive networking (TSN), an association of several sub- standards that are being developed within the framework of the standardization group IEEE 802 (Time Sensitive Networking Task Group) and that define mechanisms for data transmission with the lowest possible latency or high availability. The basis of these TSN networks, however, are innumerable sensors, devices, and systems that are increasingly being equipped with artificial intelligence and Smart Machines & Factories spoke to Thomas Brand at Analog Devices to take a look at cyber security for industrial Ethernet.
