The machines of different manufacturers shall be identifiable in a standardized manner. To realize this, a number of basic and static information like manufacturer name and model number are offered on the interface.

The machines of different manufacturers offers their states in a standardized manner.

The machine is expected to offers all current messages such as alarms, warnings and information over the interface. These errors and warnings shall be mapped to OPC UA event types accordingly.

To facilitate the calculation of different KPIs like for example OEE, the interface offers different item values with their changing times. These times allow to calculate the durations of different machine modes.

All of these relevant times are transferred with OPC UA mechanisms. Each state change is sent to the OPC UA client, and the timestamp can be used to calculate the time durations needed for KPI compilation.
