Superimposing the Digital Twin onto the Actual Control Cabinet

With the expanded app, which will be available in May 2024, service technicians can use a tablet or smartphone to overlay the actual control cabinet with its digital twin. In other words, the technician has digital access to every individual component directly at the control cabinet. For example, if a circuit breaker for a motor must be replaced, the service technician is visually guided with AR highlighting and thus knows exactly where the component is positioned within the control cabinet – even if the cabinet door is closed. This allows components to be quickly located, especially in larger control cabinets or a line-up of such. The service technician can then use the digital twin to get all the necessary information, such as the connection point pattern and the schematics page with the motor starter combination. This also eliminates the need to search through what could potentially be very extensive paper documentation. So the app quickly leads the service technician or maintenance employee through the tasks that must be done.

If, as an example, a contactor must be replaced, the digital twin doesn’t just show the manufacturer’s specifications for the component, it also refers to the electrical engineering documentation. The technician notes the replacement of the part using the redlining or greenlining functions and then the engineering department can simply implement the changes on all the pages of the electrotechnical documentation. If there are cross-references to other schematics pages, these are then also automatically updated in engineering. The best thing is that collaboration in Eplan in bidirectional – from service into engineering and vice-versa.

A QR code generated in Eplan connects the control cabinet’s documentation with the actual control cabinet in operations. The project is stored in the Eplan Cloud and is therefore clearly assigned. The 3D view of the control cabinet layout is superimposed onto the mounting panel and/or the control cabinet itself through the AR functionality. The digital twin from Eplan Pro Panel is overlaid 1:1 onto the components within the control cabinet – simply using a tablet or smartphone. With the AR app, the project documentation is visualised as a schematic in 2D or as a virtual image of the control cabinet in 3D.

Split-screen technology allows the schematics and the AR model of the control cabinet to be displayed side by side if desired. This allows faults and errors to quickly be traced back to their source. Another practical advantage is that equipment lists, bills of materials, cable overviews and other evaluations such as topologies can be accessed via cross-references. It ultimately means there is no need to page through the schematics. The complete documentation is available to view at any time and from anywhere in the world through the Eplan Cloud. This simplifies collaboration across departmental boundaries. It also accelerates and simplifies service and maintenance processes. What’s more, the electrotechnical documentation is always accessible and always up to date, which also makes future maintenance and service operations even easier.

• Fast localisation of components for servicing
• Linking the digital twin and actual control cabinet
• Access to the complete and up-to-date project documentation
