Sample Message for Timeseries Data¶
Timeseries Data¶
The sample data message is relevant c/{clientId}/o/opcua/v3/u/d/t topic.
Only timeseries is created by this operation. Update and Delete operations are not possible.
Note
The code below is just a json representation of the UADP message format. You have to create an UADP message in binary format before sending it to the topic.
