The use cases covered in this version are listed in Table 15. These use cases can be broken into Telemetric and Asset Management categories. Telemetric use cases publish dynamic data e.g. to a cloud application for remote monitoring. Asset Management use cases require client server interaction with the information model typically for on-premises applications.

|
Batch Configuration |
Downloading device configurations for a batch of devices |
|
Regulatory audits |
Verifying device versions and certifications |
Use cases define the content of this Device Information Model. NAMUR Open Architecture (NE175) defines uses cases with parameters, names and semantic ids, which are an important input for the definition of the PA-DIM. Additional details about these use cases can be found in the NAMUR descriptions found on their web site referenced in Section 2.
