This document  describes  an  information  model, which  aims  to  cover  the whole Compressed Air System. A typical Compressed Air Systemconsists of several devices, such as compressors, dryers, filters, air quality monitoring units etc., it is commonly also equipped with a Main Control System. The latter is used to control and/or monitor the connected devices and gather information from the same. This aggregated information is often provided to higher level systems through existing field bus technology (e.g. Profibus, Modbus, CAN Bus), with the drawback that the content and structure of the provided information is highly dependent on the manufacturer of the Main Control System. With this specification an integration in a Main Control Systemwould be possible.

The variety of Compressed Air Systemis rather wide. It could be e.g. two compressors and a Main Control Systemand a basic compressed air treatment as a minimum configuration. More complex Compressed Air Systemhave several compressors which must be controlled and several Airnetsof different pressures with specific dryers, filters etc.

Therefore, this specification covers a very broad range of systems as well as of applications.

A typical more complex Compressed Air Systemis described in the following figure:
