Cyber-security: a journey, not a destination
Cyber-security has been a hot topic since the Stuxnet incident of a few years ago. Previously it was thought that securing the ‘top end’ of an organisation was adequate, but this incident and others like it completely changed the security landscape and highlighted vulnerabilities in the de-facto automation architecture that previously had not been considered. Chris Evans, Marketing & Operations Group Manager at Mitsubishi Electric Europe B.V. Automation Systems Division, explains.
Ditch the upgrade, source the obsolete part
Upgrades are a normal part of all aspects of life. Everything from phones, computers and hardware to software, cars and even partners can fall victim to the upgrade cycle. Should they be deemed to be in need of a refresh, there is always a simple way of doing it; whether that’s clicking a button, buying online or hanging out in trendy bars... However, if the process wasn’t so easy, would we be so willing to change?
Strong demand for uninterruptible power supply (UPS)
Frost & Sullivan’s new research into the strong demand for uninterruptible power supply (UPS), as industries in Europe are losing EUR150 billion due to power issues, raises some interesting points, especially in terms of manufacturers needing to introduce energy-efficient UPS systems.
How accurate are your radiometric readings?
A thermal imaging camera only reads the electromagnetic radiation it receives in a specific range of wavelengths. To display this reading the camera makes several calculations to convert data into actual temperature and one that is vitally important is emissivity.
EN ISO 14119:2013, new standard for guard interlocking devices
EN ISO 14119:2013, 'Safety of machinery - Interlocking devices associated with guards - Principles for design and selection', has been harmonised to the Machinery Directive 2006/42/EC and supersedes its predecessor, EN 1088, on 30 April 2015. David Collier CMSE, Business Development Manager with Pilz Automation Technology, highlights the main changes to be aware of.
Robotic units in the bakery sector
Chris Sumner, MD of FANUC UK, considers why robotic uptake within the bakery sector has been lower than that in other manufacturing sectors.
Meeting the new efficiency standards for power drive systems
Improving the efficiency of electric motors has been an on-going objective across the world, with several standards now in place to help achieve this goal. However, it is generally recognised that a broader view is needed to fully maximise the efficiency of the entire drive train. This requires engineers to take account of the efficiencies of the starter systems, as well as the equipment attached to the motor; which has led to the introduction of a new standard, EN50598. Yasar Yüce, Product Manager at Bauer Gear Motor, looks at the reasoning for the new standard as well as the implications for manufacturers and end users.
Coupling options in metal manufacture
Selecting rubber-in-compression couplings as a cure for vibration and shock loading on arduous applications in the metal manufacturing industries can not only cut maintenance and downtime but also reduce operating costs and extend the life of the machinery and equipment to which the couplings have been fitted.
