  • Why Zone Cabling Architectures Make Sense

    true
    When Power over Ethernet (PoE) was introduced in 2003, it was available for only a handful of low-power operations and devices. Today, PoE is one of the fastest growing networking applications. A wide range of enterprise devices and technology rely on PoE, including lighting, access controls, laptops and desktop computers, IP cameras, information kiosks, industrial automation equipment, and wireless access points (WAPs). With the advent of digital buildings and the Internet of Things (IoT), PoE is poised for unprecedented expansion… Read more »

  • How to build network redundancy at the wellhead

    true
    Today’s oil and gas operators are moving decisively to capitalize on the innovations driven by the Industrial Internet of Things (IIOT). Benefiting from these networking opportunities means real-time remote monitoring of wellheads. This gives operators the power to continually ensure consistent pressure and flow, as well as transmit data throughout the network for ongoing process improvement. Wellhead control automation often includes compressor control, pumping unit control, gas lift control, injection control and more. Read more »

  • Understanding Distance Limits with Multimode Fiber

    true
    Multimode optical fiber is the most common media choice for both backbone and horizontal distribution within the local area network (LAN) including campuses, buildings, and data centers. Let’s take a closer look at the types of multimode fiber options based on bandwidth and distance needs. 1 GB/S NETWORKS The majority of enterprise fiber networks today still run 1000BASE-SX, delivering up to 1 Gb/s over multimode. OM1 cable will support 1000BASE-SX out to 275 meters, and that distance jumps to 550… Read more »

  • Modular Plug Terminated Links and the Leviton and Berk-Tek System Warranty

    true
    At the end of the day, we all want the most efficient and cost-effective calbing options possible – even if it means being untraditional. This is the story of Modular Plug Terminated Links or MPTLs. With an MPTL, there is just one patch cord in the telecommunications room, and the permanent link is terminated at the other end with a plug, so it can be inserted directly into the device – eliminating the equipment cord. MPTLs make sense because as… Read more »

  • When Should You Use VFD Cable?

    true
    With all the process efficiency and energy savings benefits that variable frequency drives (VFDs) offer the production environment, it’s not surprising that operations of all kinds rely on them. In fact, some facilities run upwards of hundreds of VFDs, helping them precisely control nearly every motor they use.With all the motor life and uptime benefits VFD cable offers, it’s kind of surprising that everyone is not using them on every VFD. In fact, by my estimate , only about 20%… Read more »

  • New Network Monitoring Technology Introduced at Homeland Security Event

    true
    I recently had the honor of being invited back for the second time to speak at the semi-annual meeting sponsored by the Industrial Control Systems Joint Working Group (ICSJWG) within the U.S. Department of Homeland Security. I presented some exciting information on new network monitoring technologies, building significantly upon the information I presented last year.  Read more »

  • Single Pair Ethernet Drives Ahead

    true
    As its name suggests, Single Pair Ethernet (SPE) cabling uses only one pair of wires to transmit data, as opposed to the two pair that have long been standard in the majority of Ethernet cabling in use worldwide. The potential benefits of reducing the “guts” of a cable by upwards of 75% are fairly intuitive: reduced weight, reduced cost, smaller footprint, easier installation, etc. Of course, the potential drawbacks can be equally intuitive—less internal cable structure can mean shorter range… Read more »

  • Triton Malware – New attacks emphasize need for more cyber security

    true
    It’s been nearly two years now since the heinous Triton malware incident was initially publicized. Many specifics were never released for security reasons, but as readers might be aware, a very large petrochemical facility in Saudi Arabia observed one day that their safety system—the commonly deployed Triconex product by Schneider Electric—was engaging and shutting down production, yet no threat could be found. They brought in Schneider Electric and then malware experts including FireEye and soon discovered that the culprit was… Read more »

  • Trends in Rail Transport

    true
    As in other industrial environments, the rail transportation industry is being significantly transformed by digital technologies and the emergence of the Industrial Internet of Things—or as my colleagues in this industry often refer to it, the Railway Internet of Things. Like network operators in industries such as manufacturing or utilities, they are tapping into “Big Data” opportunities to fuel productivity—in this case, forwarding vital goals like keeping trains running on time, making them safer, and optimizing maintenance resources. And, perhaps… Read more »
