Last week’s blog post covered the uses for Category 6A cable, including emerging applications and recommendations for adoption by industry standards bodies. This week, we take a look at the factors that go into the choice of a Category 6A cable. While all Category 6A products must meet the same base set of specifications, they are surprisingly different in their physical properties, and how well they deliver at the extremes of performance. Those extremes are important, because the extremes of today are the expectations of tomorrow.

Here are the key considerations to weigh when choosing a Category 6A cable.

While IT and controls engineering traditionally have been two widely separate disciplines, the adoption of Ethernet for industrial networking has increasingly brought the two worlds together.

One area that calls for a multi-disciplinary approach is cyber security. Cyber security attacks on critical infrastructure industries have been rapidly growing in number, plus there is heightened concern about it at the executive level.

As result of these trends, our organization is prioritizing investment in cyber security technology and know-how. When it comes to ICS security, we want to provide solutions that meet the requirements of both IT and engineering professionals.

A reflection of this is our recent acquisition of Tripwire. Today, I am going to introduce you to this innovative organization and their role in helping you, our industrial customers and partners, see the big picture of ICS security.

Category 6A twisted-pair copper received much attention when it first hit the marketplace in 2005. But adoption has been slow, since the 10 gigabit per second (Gb/s) capacity of Category 6A exceeds the requirements of most LAN applications. However, times are now changing. Data rates in the enterprise continue to climb. More devices than ever are being connected. Emerging applications demand higher performance and faster speeds. And those trends haven’t escaped the notice of industry standards bodies.

Ten years ago, buying a glossy magazine and reading it was a self-indulgent treat. Today, I read a wide variety of magazines on my iPad. In particular, I have gone back to National Geographic. Its digital cost is affordable, its photos and videos are spectacular, and I don’t have to make agonizing decisions about storing or recycling a great-looking document.

Over the last decade, you have likely implemented an industrial wireless application and decided afterwards that it really was not worth the cost and drawbacks that came with it. Like my old, dusty hard copy National Geographic, industrial wireless solutions may be filed in the “don’t suit me” compartment of your brain.

I would like to urge you to dust off your thinking and consider how advancements in reliability, performance, security and ease-of-use have changed the industrial wireless game.

Today, I will look at three applications for moving people or goods, and explain how they save money and make data collection and reporting easier. I will also explain how some of the earlier issues with industrial wireless have been addressed with today’s technology.

Hot aisle and cold aisle containment are the fundamental data-center energy efficiency solutions.

As business increasingly relies on the data center to create and drive business, power densities are increasing also. Data Center managers look to support higher power density, increased cooling demand, while searching for solutions to keep operating costs down and service levels high. This post will present a fresh look at cooling strategies, in terms of the degree of control offered at the room, row, and cabinet level and the how and when to apply them to provide energy efficient solutions for your business needs.

The adoption of new technologies in electrical substations has improved communications, but it has also made these networks more vulnerable to cyber threats.

In the past, electrical substation design focused on safety, ease of use and reliability. Security wasn’t a concern. As the substations have grown more complex in their design and threat sources more sophisticated, security has become a priority.

A substation with lax security is more likely to fail or have issues – and these failures can be expensive. So, it’s necessary to have a holistic security policy in place that can help minimize or contain threats – both internal and external, as well as intentional and unintentional.

VFD cables are used to connect Variable Frequency Drives (VFDs) to motors and, when specified correctly, they play a large role in mitigating harmful electrical noise. This noise can disrupt production and lead to downtime or quality control issues, which can be a major drawback to VFDs that otherwise have a quick payback.

This article gives you a preview of an upcoming webinar we are holding on parallel VFD cable. The webinar will help you specify the right cable for high-power motor and drive applications. You can register for it using a link at the end of this blog.

Since it first came on the scene in July 2003 with the ratification of the IEEE 802.1af standard, Power over Ethernet (PoE) has become a “must have” for LAN deployments.

The first iteration, Type 1, had the ability to deliver up to 15.4 W of power over two pairs of a telecommunications cable from the source to support VoIP phones and other devices. The second iteration, IEEE 802.3at-2009 Standard, also known as PoE Plus, had the ability to deliver up to 30 W of power over two pairs from the source to the powered device. Even so, it wasn’t the most efficient and many IP-based devices now simply require more power.
