Secure remote access solution for Industry 4.0
and IoT applications

The platform for secure remote maintenance and reliable IIoT applications

Big-LinX is the platform developed in-house by ADS-TEC Industrial IT for secure remote maintenance and reliable IIoT applications. In the age of Industry 4.0 and the Industrial Internet of Things, factories around the world are becoming increasingly interconnected, digitalised and therefore more complex. That’s why remote maintenance and greater efficiency in controlling production systems and machines are becoming key factors. The award-winning Big-LinX not only helps you avoid travel costs, but also the expense of prolonged production downtimes, enabling you to effectively leverage the full potential of Industry 4.0. 

How Big-LinX® works

To keep your production running smoothly, you need to respond swiftly to disruptions as soon as they occur. If service is required, the system manufacturer connects to the Big-LinX rendezvous server via a VPN connection and the system likewise via the ADS-TEC firewall. A consistently secure and strongly encrypted connection is created with the integrated smartcard for authentication. Now the process of remote diagnostics and analysis can begin, problems can be fixed or spare parts identified and ordered to get your equipment up and running again as soon as possible.

From the introduction of the test kit to registration, to setting up alarm rules and many other practical explanatory videos on the subject. 

Maintenance and predictive maintenance

Preparing maintenance

Can the condition of machines be monitored automatically? Using our IIoT applications and services, you can monitor and proactively maintain machines in real time. The benefits include faster diagnosis, more accurate forecasts as well as trends, and easier drafting of recommendations for action. The ideal basis for needs-based maintenance that cuts costs and saves a lot of time.

Secure cloud hosting

The servers are located in Europe – access is guaranteed worldwide, even in China – thanks to a secure-access gateway solution. The advantage: your entire machine data are extremely well protected and the processes are all fully compliant with applicable regulations and specifications such as the GDPR.

Configuration made easy – no-code platform

Big-LinX makes it possible to implement sophisticated IIoT applications even without programming skills, enabling machine data to be read out or alarms visualised – without having to write a single line of code.
