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.

If you are more comfortable programming PLCs than implementing cyber security measures this series of blogs is for you. Its goal is to give you an overview of the security functions built into network devices so you can implement the ones that are appropriate for your application.

In the first blog, I briefly discussed Defense in Depth and how it is important to implement multiple types of defenses at different points in the control network. This best practice maximizes protection from cyber security incidents, whether they are accidental or intentional.

Part 1 also looked at ways to control access to specific devices, such as industrial Ethernet switches. In today’s blog, we look at ways to control the types of messages any device or computer can send or receive on a network.

Belden will once again be participating in the Data Center Dynamics (DCD) Converged Event, taking place March 17th and 18th at the Marriott Marquis in New York City’s Times Square.

DCD is the world's leading peer-led data center conference and expo series, and the annual event is now bigger and better—and focused on the enterprise! The result of one-day regional events being consolidated into three larger-scale events that focus on primary data center verticals, DCD Enterprise USA has been specially designed for senior data center end-users and operators dealing with the increasingly complex and heterogeneous mission critical enterprise environments.

Earlier this year I published our first article on the Smart Factory of the Future. It described a vision of manufacturing where systems are more intelligent, flexible and dynamic.

In the future machinery and equipment will have the ability to improve processes through self-optimization and autonomous decision-making. This is in contrast to running fixed program operations, as is the case today.

“Cyber-physical” systems will also be important, with feedback loops where physical processes affect operational programs and vice versa.

Let’s now consider the manufacturing LAN and its communication systems. How does it need to change to realize the vision of the Smart Factory?

In my last blog, we talked about hot-aisle and cold-aisle containment as an ideal solution for keeping equipment cool and saving energy in today’s high-density virtualized data centers.

Depending on the location of the data center and location of the containment system within the data center, some form of fire detection and/or fire suppression is required inside the enclosed aisle.

Let’s take a closer look at fire detection and suppression in the data center and how aisle containment systems can impact the requirements.

The results of the 28th annual Control Engineering Engineers’ Choice Awards are out and I am excited to see that one of our flagship products, the Tofino Security Appliance (specifically the Tofino Xenon version), has received an Honorable Mention award.

The award recognizes control and automation products released in 2014 that are exceptional based on technological advancement, service to the industry and market impact. The Tofino Xenon was recognized in the category of Control Security.

Of significance to Belden is that the winners are not chosen by an expert panel, but by automation professionals from Control Engineering’s subscriber lists. These are people like you who have hands-on, day-to-day interaction with the technologies. Also, you all are responsible for and influence technology purchases.

In case you are not familiar with this product, let’s take a look at some of its unique strengths.

There are some exciting new developments in the world of BASE-T Ethernet and wireless.

Last November, the IEEE 802.3 working group held a Call for Interest (CFI) on the need to develop the next generation BASE-T for wireless access points (WAPs). The main issues raised in the CFI were that next generation 802.11ac Wave 2 devices will require multi-gigabit Ethernet data rates, and that there is a gap between the 1 Gb/s and the 10 Gb/s data rates needed to support Wave 2 devices.

The IEEE 802.11ac wireless standard was approved in December 2013. Current Wave 1 devices are using 80 MHz channels and Single-User Multiple-Input and Multiple-Output (MIMO) antennas with a maximum radio speed of 1.3 Gb/s. To support these devices, the network connection speed needs to be at least 75% of the radio speed. Therefore gigabit Ethernet connections over Category 6 or high-end Category 5e cabling are adequate to support Wave 1 devices.
