Nick Denbow’s European report: Fieldbus, government interference and news from the UK

July 2018 Editor's Choice News

The German organisation Profibus & Profinet International (PI) publishes annual statistics on the numbers of devices installed with interfaces equipped with their communication technologies, which also include ProfiSafe and IO-Link. The trend towards Profinet increased in 2017, with 4,5 million new nodes installed, an increase of 25% on the previous year figure, which brings the total number installed to 21 million. Possibly because of the rise in Profinet systems, the Profibus DP numbers added seem to have reached a plateau over recent years, with a population of 60 million.

Profibus PA and ProfiSafe node numbers are growing strongly in the process automation field, with the ProfiSafe adoption growing 25% in the year, adding two million nodes to reach nine million in total. Similarly, IO-Link device numbers installed in the year increased 50%, adding 2, 8 million to achieve a population of 8,1 million, linking sensors and actuators to a PLC as a subsidiary network below the fieldbus/Profinet level. PI recently published an IO-Link wireless specification, and demonstrated the technology at the Hanover Trade Show earlier this year.

Government interference

Legislative rulings have affected businesses and consumers across the EU recently, with the European Union’s General Data Protection Regulation (GDPR) causing avalanches of email asking for a subscriber’s permission to be re-registered with every firm they have ever dealt with, to allow them to record the fact. Even companies from outside the EU will face financial penalties, if they send out emailed newsletters or promotional messages into EU subscribers, without having these permissions confirmed, registered and recorded!

In the US, the EPA, under the Trump administration, has dropped most of the more Draconian measures that they had originally proposed to impose on chemical plants, after the explosion at West Fertilizers in Texas that killed 15 fire-fighters and injured 260 people. The CSB report on the incident also listed 19 other Texas facilities that store large amounts of ammonium nitrate fertiliser, and are located within half a mile of a school, hospital or nursing home. One regulation that will be introduced in Texas is that local fire marshalls will inspect all sites storing ammonium nitrate, once a year. Hopefully, this might help prevent any further explosions that might result in large off-site consequences.

The changes that were proposed by the EPA and that will not now be introduced, include (1) the need to evaluate options for safer technology and procedures that would mitigate hazards; (2) the requirement to conduct a root-cause analysis after a catastrophic chemical release or potential release incident; and (3) performing a third-party compliance audit after an accident at a plant involving the release or potential release of chemicals.

In the UK, Barclays Bank, rather than the government, is reassuring UK exporters worried about Brexit and trading afterwards, with a survey that shows 39% of international ­customers would be more inclined to buy a product if it displayed the Union Jack. This was especially true for consumers in Asia and the Middle East (India, 67%; UAE, 62%; China, 61%), and also for younger consumers generally, where nearly half said this would encourage them to make a purchase. For over 55-year-olds (who maybe had more life experience) the figure dropped to a quarter. It’s all statistics!

Research projects

Splitting water into hydrogen and oxygen was first demonstrated by Fujishima and Honda using a titanium dioxide electrode. Since then, scientists have been on the hunt for the ideal material to perform the task, as hydrogen is a very useful, green fuel for portable power. Now, a team from Exeter University has made a significant hydrogen energy breakthrough, developing an electrode that splits water using only light. The photo-electrode, which is made from nanoparticles of lanthanum, iron and oxygen, absorbs light before initialising electrochemical transformations to extract hydrogen from water. The team is currently working on further improving this material to make it more efficient, to produce more hydrogen.

At the Drives & Controls Exhibition in the UK this year, all the motor manufacturers were showing the condition monitoring capabilities of their offering, usually measured by vibration monitoring sensors. Possibly ABB went one step further, showing a sensor assembly that can be attached to almost any low-voltage motor, existing or on a new project. Transmitting information over Bluetooth, the sensors require no wiring, and are attached directly to the motor’s frame. Within the unit, sensors collect vital data points like vibration, sound and temperature, and upload that information via an ABB gateway or smartphone to the cloud, where it is analysed.

The results are sent back for optimising performance and predictive maintenance, just like a roving maintenance engineer.
