Ethernet has become a prominent method of communication in industrial automation. Its ease of use, speed, and versatility have allowed it to surpass the older, closed-off, proprietary means. Not only that, but Ethernet has also introduced automated systems to a whole new world of possibilities with connections to high-level IT systems, remote/mobile access, cloud computing,…

With the popularity of the Industrial Internet of Things (IIoT), industrial Ethernet applications are expanding. The IIoT is helping collect data on plant floors and is using Ethernet cables, connector and switches as key components. Industrial protocols such as Modbus TCP/IP and EtherNet/IP help connect edge devices and instruments to controllers and HMIs. Not only…

Ethernet is used extensively in industrial automation applications, and in the office environments of industrial firms. This leads many to believe the network security procedures used in the office can simply be applied to industrial networks. While this would make implementation easier, it’s not that simple as there are some important distinctions between security practices…

Deterministic Ethernet and Time Sensitive Network (TSN) are current industrial automation buzzwords—both related to how control data and information can flow through network pipes. A little history and understanding of industrial fieldbus communications will help explain where we are now and where we’re going with deterministic Ethernet and TSN. The history starts decades ago when…
