If OPC UA-capable devices are in-stalled in the plant, they can even communicate directly with EB and thus report their existence or modification to the digital twin.46 This means that the service is always up to date.47 And a team does not have to scan the actual state of the plant and then add it before any conversions.48 To ensure that this procedure is also open to operators of older plants with corresponding documentation, Aucotec has developed a migration concept for EB that checks existing data during its transfer, in some cases supplements or merges it and thus raises it to a digital twin level.
