Securing remote maintenance and fault response in minutes

By OEM Update Editorial May 7, 2021 4:30 pm IST

A VPN-based remote assistance service reduces a specialist machine builder’s fault response times from days to minutes.

Maximator, a secure remote monitoring and maintenance package from B&R has helped our clients to reduce on-site visits made commissioning more efficient and improved response times for troubleshooting its high-pressure hydraulic and pneumatic systems. Maximator is among the world’s leading manufacturers and suppliers of pumps and boosters, valves, fittings and tubing for high-pressure gas and fluids. Its UK subsidiary also assembles these components into specialised testing, pressure and control systems. With a long history relying on B&R for automation technology, Maximator also turned to B&R to select a remote maintenance solution.

Secure Remote Maintenance now allows Maximator UK to remotely access its installed base of machines and show HMI systems to their customers to support and guide them through production tasks or to provide programming and troubleshooting of software. Before Secure Remote Maintenance, Maximator UK’s engineers would need to travel extensively to customer sites, so they can understand how they were interacting with the machine, provide support during commissioning or fix faulty configurations.

Furthermore, once the machine is operational, customers often want to add functionality to further automate their process, especially during a production bottleneck or a repetitive task is required. This often entails writing software. Maximator UK’s engineers can now remotely access the machine and update the software, saving both time and money. “Now, if a customer has a production challenge, they simply call us and we can connect and help them solve the problem within minutes,” says Maximator UK’s managing director, Jon Butler. “That is a huge benefit to the customer as they do not have to schedule in a technician to go to the site. Alternatively, our engineers can proactively alert end users to any upcoming service or maintenance issues of which they may otherwise be unaware.”

Secure package

The Secure Remote Maintenance package comprises three components: SiteManager is a small, secure, Internet-enabled modem that connects the machine in the field via the installed PLC, to the Internet and the GateManager server. The SiteManager only has to be installed once. If the device is replaced, all parameters are transferred from the machine controller to the new Site Manager. It is available in three variants for different Internet connections: LAN, WLAN or mobile network modem (LTE/4G/3G/GPRS). GateManager is the service that then connects all the various SiteManagers to each other. GateManager verify access rights before establishing the connection between technician and machine via B&R’s server.

“What impressed us is the ease with which the secure remote maintenance system can be set up and activated on a machine,” says Butler. “It really is out- of-the-box and plug-and-play.” Some Maximator UK machines feature a system that sends emails every month requesting that customers take hourly or cycle count readings. For some customers this can be burdensome.

Using Gate Manager, Maximator UK is able to remotely take the cycle count readings and instantly spot if there are any problematic trends. “Customers are very receptive to that level of service,” says Butler. “We see it as a great added value to our products, and we don’t even need to charge extra for it, as it not only saves us money by avoiding site trips to resolve minor issues, but also enables us to provide a better product to our customers.”
