We have an OPCUA Server (Server) that sends an array (Array) of length 500 every second. We need an OPCUA Client (Client) to stream this array to cloud.

  • First, we use UaExpert an open-source software as Client. Here we can see a node for Array which has values of Array[0], Array[1], Array[2], Array[3], … Array[499]
  • Next, we use Cognite OpcUaExtractor as Client to stream data to cloud. But we result in only Array[0] being sent in each instant (second). I have tried to adjust different parameters in config file with no success.

Hi again,

I am now working on the OPCUA server that supports pubsub and came to a question. The question regards understanding how the Cognite OPCUA Extractor interprete opc datavalues and ingest them as timeseries to CDF.  Doese it use opc source time stamp or server time stap? 

Thanks for your support

The extractor uses SourceTimestamp exclusively.
