OPC DA Data Source

OPC DA data source is the process of writing data from the OPC UA server to the currently selected TDengine Cloud instance via a connection agent.


There is an additional charge for extracting OPC UA . The charge depends on your TDengine pricing plan. For more information, contact our team or your account representative.


  • Create an empty database to store your OPC DA data. For more information, see Database.
  • Ensure that the connection agent is running on a machine located on the same network as your OPC Server. For more information, see Install Connection Agent.

  2. In the Target DB, select the database of the current TDengine Cloud instance as the target database.
  3. In the Service endpoint field, you need to configure the address of the OPC DA server,<,localhost>/Matrikon.OPC.Simulation.
  4. You can click the Connectivity Check button to check whether the communication between the Cloud instance and the OPC DA server is available.
