Thanks to the direct connection to the Comos engineering software, all engineering data can be linked and thus enable a holistic view of the plant. Changes or annotations can be easily and securely transferred through the bidirectional exchange between the systems. The integration of location data also supports on-site navigation. If necessary, augmented reality displays the relevant information to the user on a mobile device such as a tablet, smartphone or data glasses. The user can edit the data directly in the field and, for example, document work packages as "done" and import photos and notes back into the corresponding information sources via a bidirectional interface. This information is then accessible to all authorized employees and in turn can be processed directly. By contacting the service technician via video chat, unplanned plant downtimes can be reduced to a minimum or avoided altogether. Use cases include commissioning, inspection, mobile maintenance, and remote access to experts. A continuous Ethernet connection within the system is not necessary, as data processed by the offline function can be synchronized retrospectively.
