Setting a Custom Object Model for Data Aggregation
Scenario
You want to aggregate data by generating an individual node, which has multiple OPC UA nodes as properties. On this purpose you must prepare and import the custom data model, and then export this configuration to an OWL file.
Prerequisites
- You prepared the OPC UA data model (JSON) file to import, which defines the custom object model that you require. For background information, see JSON File for Object Models.
- For enabling the alarm functionality and event notification, in the OPC UA data model (JSON) file to import, you also specified the configuration of the following mandatory properties: Alarm.AlarmDPE, Identifier, AlarmMessage, AlarmStatus, and AlarmTimestamp.
For more details on the configuration of those properties, see OPC UA Mandatory Properties for Custom Object Models.
- You are trained and authorized to work with system libraries. Also you are authorized to handle libraries for the specific customization level (L4-Project, L3-Country, or L2-Region) where you want to create the new library.
- System Manager is in Engineering mode.
- System Browser is in Management View.
