25 www.drivesncontrols.com February 2021 TALKING INDUSTRY n Chris McComb BSc MBA CEng PI UK Profibus & Profinet A chartered engineer withmore than 25 years’experience in the automation industry, Chris is managing director of the system integrator iTech. For more than 15 years he was a corporate account manager with Siemens and ABB, and before that he was a special-purpose machine designer and builder. Daniel Phillips-Fern UK Country Manager Ixon Cloud Since joining to Ixon to lead its UK division in 2018, Daniel has been on a mission to help machine-builders and system integrators to improve their service, support and data analytics offering through the power of IIoT. This resulted in considerable growth for the company in the UK over the past two years. Michaël Lefeuvre Product Manager Europe Red Lion Controls Michaël Lefeuvre has spent more than a decade working in various departments of Red Lion Controls. An important part of his job is to position the company’s portfolio in the regional markets and to support its sales and marketing team. Andy Pye Webinar Chair and Consulting Editor DFA Media Andy has edited many leading UK design and manufacturing titles over the past four decades. He is a graduate material engineer and spent five years in engineering consultancy before entering technical publishing in 1980. compare it across different assets. “A pilot is a great way to start, because that's a low-cost way of implementing a project,” Phillips-Fern suggested. “And during the pilot, you can then get a real idea of the total cost, as well as some tangible benefits.” Enabling technologies Chris McComb (Profibus & Profinet International) led the second section of the discussion on enabling technologies. “Every manufacturer, every type of network, every age of machine – all of that can be connected,” he said. “Brownfield sites will be a mix of technologies. “If you are taking all your data from the network, the network itself must be healthy,” he added. “An industrial plant may be new or old. Good infrastructure needs constant health checks, with preventative maintenance on the technology, the hardware, the systems and the mechanical parts. “But,” he continued, “networks are often overlooked – network infrastructure can be copper, it can be fibre, it can be wireless and is usually a mix of all those different technologies. Transporting data Moving on to the third theme, Michaël Lefeuvre (Red Lion Controls) suggested that “the process of monitoring a production line is moving from a pyramid system to more of a service system, where the system goes to collect the data which it needs directly from the sensor. Before we were just getting data out of the PLC. Everything is moving in this direction, which means that even if the PLC doesn’t work, you still can get data out. “Despite the flexibility, customers do have challenges with this, one of which is security,”he continued.“Making everything connected can have an influence on different parts of the factory, whereas before this was not the case, because each part was autonomous and just connected with local devices. But solutions are arriving on the market and I think that is good for the future. “The security risk is manageable and there are a lot of strategies; despite the media attention they get, big cyber- attacks are rare,” Lefeuvre added. “Cyber problems are more likely to be a small- scale malevolent action or just due to human error (mishandling actions). “For example, you might ask a subcontractor to come into your factory to install a new machine. And on his computer, he has a fixed IP address, which is already used in the factory. He connects his computer on a simple switch without any security. And you create a double IP on the same network, which causes trouble. These types of thing happen if you don't put in security and if you don't create secure areas or protected areas.” A member of the audience, Geoff Grant of MP Filtri UL, a manufacturer of condition-monitoring equipment, commented that his company has many customers that want remote monitoring via cloud and would like a plug-and-play solution. Phillips-Fern explained that is exactly what Ixon offers for connecting devices to the cloud. “In general terms, regarding the sort of technical and security implications, I agree with Michaël that human error is very much a part of all this, and a lot of cyber- security attacks are attacks or internal issues that happen and are not actually intentional – simply, like you say, human error. "Because Ixon is a cloud-based platform, we are completely scalable,” Phillips-Fern continued. “We don't have to worry about local conditions. One thing I do hear a lot on my travels is: ‘We don't quite trust the cloud, we don't quite get it’. I always say to them: ‘OK, you don't trust the cloud. But you’re walking around with an iPhone that's got your banking apps on and you use Amazon!’ So it goes back to your network, your infrastructure, your network as a backup, proper DMZ, using managed switches. And it goes back to using the correct people with a fixed certification and the correct understanding of that network.” n Talking Industry The Panel You can viewa video of the complete Talking Industry discussion via this link: https://forms.gle/BShcBY9y9AgX4Ldt9
