Interoperable Energiedatenbereitstellung mittels Verwaltungsschale

In view of increasing requirements for CO₂ transparency and sustainability, manufacturing companies are increasingly obliged to record and evaluate energy-relevant data. This article presents an approach for workpiece-specific measurement of the electrical power demand of machined components. This is implemented by using a digital twin based on the asset administration shell and communication-capable sensor solutions. The time-resolved power demand and the carbon footprint derived from it are stored in the workpiece’s asset administration shell. This enables companies to transparently identify the energy and emission output of their products and, by analysing the energy data, identify potential savings in the manufacturing processes in order to reduce energy costs.
