5.8 Providing Data for KPI Calculations ToC Previous Next

To facilitate the calculation of different KPIs like for example OEE, the Machine Tools interface offers different machine times. These times allow to calculate the durations of different machine modes. To calculate the KPI, additional data not provided by the interface may be necessary.

Some of these relevant times are transferred via the event mechanism in OPC UA.

For detailed information about KPI calculation and possible values of the information model to use, please refer to Annex B.
