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, ... Read More
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 ... Read More
Knowing when to choose a managed Ethernet switch instead of an unmanaged Ethernet switch for your industrial grade networking solution might not be obvious. Plus, the price differential between an unmanaged and managed switch is significant and can impact the overall system budget.
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 ... Read More
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 ... Read More
AutomationDirect’s line of Stride Unmanaged Industrial Ethernet Switches now offers even more connectivity choices for Ethernet applications. The new Stride SE2 series DIN rail mountable switches offer up to 16 ports and include models with Gigabit Ethernet and SFP options;
AutomationDirect’s C-more Micro line of operator interfaces now includes the EA-ECOM communication expansion module. Designed for all EA3-series C-more Micro panels, it adds an Ethernet (RJ45) port for programming and PLC communications at 10/100 Mbps. The module attaches to the rear of all EA3-series panels and requires no external power. Priced at $50.00, the EA-ECOM ... Read More
Fieldbus technology has been around for more than 30 years and has been a great replacement for point-to-point wiring in many cases. It’s widely used for connecting sensors, solenoids and other field devices to PLCs and other controllers. Ethernet is the most popular fieldbus option and it comes in many flavors.
As technology advances, so does the speed at which it communicates. And with the advances made in industrial controls, the need for high-speed data transmission became a priority. As a result, Ethernet communication became more and more prevalent in industrial networks and prompted many industrial equipment manufacturers to implement their own Ethernet communication protocols. These ... Read More
Once upon a time, individual machines were stranded on an island, or just linked to other machines using a few discrete I/O and dry contact relays. Then came machine-to-machine data links such as a proprietary PLC-based network. Today, and certainly in the future, machines are being linked to IT systems.
