The AutomationML standard series IEC 62714 „Engineering data exchange format for use in industrial automation systems engineering” already contains many use cases and guidelines of how system engineering information is modelled as well as which meta information could enhance the data excahnge.
In order to specify these definitons with examples, to apply them to specific use cases, and to facilitate the first steps with AutomationML, specific issues for the modelling of data in AutomationML are illustrated in Best Practise Recommendations (BPR). In addition, the BPR shall provide a consistent realization for specific use cases and shall, thus, complement the AutomationML standard documents.
BPRs are no subject of standardization but in case of a concretization of the IEC 62714 series the content could be included in it later on – within a maintenance cycle.
AutomationML models can e.g. describe communication networks in manufacturing systems. This includes the description of logical devices responsible for the communication, e.g. OPC UA server. One object/element in AutomationML can be found in another world (communicating elements), too. Examples of another world can be the OPC UA address space/information model with OPC UA Nodes which can be addressed. The DataVariable concept helps to describe how to „find“ the element in the other world.
