35th Anniversary THE POTENTIAL TO SAVE MORE ENERGY
Significant untapped potential for electricity savings is available to the manufacturing industry across the globe, according to new research from Siemens Financial Services (SFS). The study estimates the industrial electricity- efficiency potential, which is defined as the proportion of current electricity consumption that could be saved if more electricity-efficient equipment were installed. Amongst the examined geographies, the figures for potential energy savings range from circa 14% to levels approaching 20%. In the UK, the industrial electricity-efficiency potential is about 14.2%. Together with Spain (14.2%), it ranks among the leading countries in industrial electricity-efficiency, followed by Germany (14.5%) and France (15.1%). The electricity-
efficiency potential is greater still in developing economies such as China (17.2%) and Russia (19.1%). Although the figures attest to a high level of electricity efficiency in UK manufacturing, further potential to reduce electricity consumption remains, particularly in production processes where production control systems and variable speed motors can cut usage. Manufacturers worldwide are increasingly keen to focus on installing more electricity- efficient equipment to reduce the consumption and cost of electricity. These can range from optimized motor-driven and automation systems to the recovery of heat from production processes for electricity generation.

WHO ARE THIS YEAR’S ONES TO WATCH?
The organisers of the PPMA show have announced the call for nominations for the Ones to Watch awards which returns to the 2015 exhibition to recognise the industry’s most talented young engineers.
Google, Facebook, the selfie, LOL, IoT and other TLAs (three letter acronyms), it’s hard to believe that we’d never even heard of any of these things in 1980 when the first issue of Process & Control (then called Process Equipment News) hit desks. This era may seem archaic to us
now, but some of the technological advances in this period still impact on our working lives today. The widespread availability of the microprocessor, mobile and remote communication technology, and the advances in computer speed and technology, meant that it was during the 1980s that engineers began to rely on software as much as the shop-floor hardware. In many ways, the hot topics of today have their roots back in the 1980s. Big data, the Internet of Things, Industry 4.0 (the fourth industrial revolution) - even though these concepts hadn’t been invented in the 1980s, the foundations for such technology were certainly created. In celebration of our 35th
Anniversary, our supplement this month includes a series of features examining technology breakthroughs, and what it means for equipment today. We hope you enjoy the nostalgia! Michelle Lea - Editor
In an effort to further acknowledge and reward young engineers across the UK’s manufacturing industries, the Ones to Watch Awards, will welcome entries from young engineers, under the age of 35, who have been working in the processing and packaging industries for a minimum of two years. Entries are welcome from all technology areas including robotics, automation and machine vision, and from any discipline including engineering, programming, R&D, marketing or sales. Email:

SMART FACTORIES CALL FOR SMART DEVICES
Lance Croutear, business unit manager, Factory Automation, at Bosch Rexroth, says Industry 4.0, or the ‘Connected Industry’, is a huge talking point within the manufacturing sector. The ultimate goal is to produce smarter factories which are more resource efficient, more productive and more competitive in a globalised economy. This presents new opportunities for manufacturers, but also new challenges in order to implement this vision successfully. While the mobile operation of machinery is not new,
there is a lack of universal interface technology between the worlds of automation and IT for the efficient integration of technologies. To analyse the likes of production data effectively, requires not only a stronger flow of information from automation to the IT world and back, but also the use of familiar languages and interfaces.
Fortunately, smart devices are arriving at just the right
time with their application software. As the industry develops more innovative and specialised functions offering maximum customer benefit, it is vitally important that these developments keep up with the concurrent entry of new IT technologies into the automation field.

ASK THE EXPERT - How do you figure out the efficiency of a drive? Part 2
We’ve already established that EN 50598 is a standard that defines energy efficiency requirements for variable-speed drives (see the April issue of Process & Control). In this second of three articles, Pete Myatt, Operations Manager, ABB Ltd. explains in more depth how these efficiencies will be calculated.
One of the great things about EN 50598 is
that it actually provides the methodology for measuring the efficiency of the complete drive module (CDM) and power drive system (PDS), where previously it was a case of guesswork based on combining the efficiency ratings of the individual components. The measurements also take account of variable-speed drives (VSDs) running at different capacities, giving a more accurate reflection of the drive’s efficiency in practice. The IE classification for motors is ordinarily taken at 100% motor speed and 100% motor torque; however this is not the case for CDM, for which the IE classification is taken at 90% frequency and 100% current. EN 50598-2 also defines eight operating points of various frequency and current loads from which the CDM losses can be determined to establish the efficiency based on the CDM running at different capacities. As we established in the previous article, EN 50598-2 also introduces a new IES for the motor + VSD combination, or PDS for motors and drives from 100 to 1,000 volts, with power up to 1,000 kW. IES classifications range from IE0, the lowest efficiency, up to IE2, although higher efficiency classes will be introduced in the future to keep pace with evolving technologies. Similarly to the CDM, the standard defines different operating points from which a more accurate efficiency rating can be determined based on typical operating levels, as many VSDs are often run at partial loads.
Next time we take a closer look at exactly
who EN 50598-2 affects and how. In the meantime, if you want to learn more about the new standard visit our EcoDesign website:
