Modern production environments require transparency regarding production status to detect the optimization potential. One of the indicators to identify this potential is the Overall Equipment Effectiveness (OEE). It is usually calculated by hand. In cyber physical production systems and an implemented Total Productive Maintenance (TPM), a permanent analysis of the optimization potential is required. This approach faces the challenges of manual efforts to gather machine data. To get a flexible sensor set, methods of energy supply and wireless radio modules are analysed. The article shows the possibilities of energy consumption to fulfil the requirements of energy harvesting.
