👥Digital Twin

About the Digital Twin

In Eliona, a Digital Twin is a representation of a device that is interactively connected with one or more assets. The representation can be a photo, but also a technical drawing.

Data sent from the assets is displayed via so-called links in the representation. This allows systems to be read remotely.

Data can also be written via the assets connected to the Digital Twin. Therefore, it is possible to make settings on the system directly via the Digital Twin.

In Eliona, a Digital Twin consists of one or more images that can be freely arranged on a canvas.
