5 Use cases

5.1 Identify machines in a standardized way

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 serial number are offered on the information model.

5.2 Current status of the machine

The user would like to monitor information about a specific MachineryItem, like the state or operation mode, for example to get a quick overview of the current state and bottlenecks (localization of errors), to recognize trends or to determine the relevant times (productive time, standby time, etc.) for subsequent KPI calculations (e.g. for calculating reliability and availability). Further information for the KPI calculation might be necessary.

5.3 Quality assurance/traceability

The user wants to be able to create a good and comprehensive representation of process parameters using standardized modelling of process values. This should enable the monitoring and traceability of production processes and consumption of energy and process media.

5.4 M2M communication and orchestration

The information model should allow a higher-level control system to oversee production and organize the orchestration of several machines in the production chain. This also requires the exchange of data between the respective machines. One purpose of this orchestration is to allow for energy and resource flexibility in scheduling and triggering cleaning jobs/ recipes in relation to the available energy and resource supply and cost.

5.5 Find all components of a machine

With the help of a standardized information model structure, components of a machine must be mapped in the same way in the different machine objects. This enables the standardized location of machine components.

5.6 Illustration of the physical systems network

If several systems are in a line, the information model should make it possible to visualize the points of contact between the different plant sections using references.

5.7 Preventive Maintenance

The standardized modelling of different counters should make it possible to provide data to fulfil the use case of preventive maintenance.

5.8 Harmonizing with existing standards

If available, the customer wants to be able to fall back on cross-industry preparatory work and comply with existing standards. The OPC UA for Machinery standard should be mentioned here in particular. If possible and sensible, different building blocks from OPC UA for Machinery should be implemented in the information model of the material supply system.
