Wireless standard harmonisation creates a new problem
As more and more wireless devices come to the market, concerns have emerged within the standards body responsible for managing the radio spectrum allocation and wireless device conformance that more guidance is needed to help ensure spectrum sharing. Tony Ingham of Sensor Technology Ltd reviews the situation.
Changes in the network security landscape
Until a few years ago network security focused on enterprise systems and relied on firewalls to prevent viruses from arriving electronically. Now there is increasing realisation that the production control systems need to be protected too, and that viruses can be uploaded by many means. Industries as diverse as manufacturing, processing, refining, power generation, and food and drink processing are all considering ways to improve the security of their plant and control systems. John Browett of CLPA (CC-Link Partners Association) considers the current position and looks at how to mitigate potential threats.
Predictive maintenance of rail traction motors: depot-based CM
A series of studies have shown that depot-based condition monitoring of railway traction motors using underfloor wheel lathes can be implemented at a fraction of the cost of Remote Condition Monitoring, says Dr Steve Lacey, Engineering Manager at Schaeffler UK.
PI technologies enable innovation for Industry 4.0
In the Industry 4.0, Internet of Things and Big Data environment, industrial communication is of central importance. The close networking of automation components, machines, systems, and IT systems needed for this, including across locations or even between different companies, is only possible with standardised and integrated communication. In recent years, Profibus & Profinet International (PI) has brought about numerous developments that meet these requirements.
Bearings contamination identified through NSK's AIP analysis
Combating contamination in bearings is one of the single most effective ways to extend bearing life and consequentially to reduce the maintenance requirement of the machinery they are fitted to. When band saw manufacturer Prosaw found that bearings were regularly failing on automated saws that had been supplied to a prominent manufacturer of building insulation, both Prosaw and the end user needed a solution quickly.
High-precision bearings for printing machinery
In order to ensure high print quality, bearings for printing machines must be carefully matched to each customer application. In this article, Dr Steve Lacey, Engineering Manager at Schaeffler UK, outlines the factors to consider when specifying bearings for sheet-fed and web-fed printing machines.
Don’t neglect palletising when automating lines
There are many different reasons for adopting robotic palletisation – usually the very last process on a packing line. It may be that you want to increase the speed of your operation, or improve the quality of the finished product. Other drivers might include overhead reduction or manual handling considerations, while in some cases staff turn around and training makes the idea of having the consistency and flexibility of a robot very appealing. Chris Sumner, Managing Director FANUC UK and Vice President of FEC (FANUC Europe Corporation), offers his thoughts on robotic palletisation.
Tip top compressed air with Beko Technologies
Compressed air is said to be responsible for approximately 10 per cent of the power usage in the UK and other mature economies. Beko Technologies is a specialist in the treatment of compressed air and management of condensates. Another major part of the business is measurement systems. Beko Technologies helps businesses improve their efficiency of compressed air usage, and has put together a list of top tips.
