Maintenance and cloud service

Efficient and secure machine maintenance
u-link makes remote maintenance easier and accelerates service processes


The remote maintenance of machines and plants is often designed such that it is very complex and time-consuming, and there is also the demand for a targeted and safeguarded functional connection to the associated IT systems. For many users, these two issues make the connection of plants around the world a major obstacle.

u-link guarantees quick and secure access to machines and plants, which makes remote maintenance easier while also allowing for the efficient management of production plants and user clients. The intuitive u-link interfaces are quick and easy both to configure and to adapt to specific processes. The innovative service on safeguarded servers in Germany also provides an online platform that ensures conformity between different IT systems when carrying out remote maintenance.

Thanks to its special properties, u-link is a great basis for the secure and affordable assembly even of comprehensive remote-maintenance topologies. The clear structure means that multiple production plants and users are easy to manage, and the option of expansion to include limitless numbers of additional routers and users means that u-link can be optimally adapted to meet a company‘s specific requirements.
