Sample Message for Event MetaData Samples¶
Event MetaData Sample¶
The sample metadata message is relevant c/{clientId}/o/opcua/v3/u/m/e topic.
Only Event Type resources are 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.
