DeltaV OPC Data Access Server functional overview > Barcode tutorial

Run the Barcode client application

This chapter describes the steps necessary to run the Barcode application with DeltaV software.

To run the application, you must first configure DeltaV software with the sample configuration. This configuration contains a few Named Sets and one module. After these have been imported and downloaded to a DeltaV controller, the application can connect and interact with the OpcSample SFC.

Import the OPC-SAMPLE area using the DeltaV Explorer:

  1. In Explorer, select Import from the File menu.
  2. Select the file barcode.fhx, and then click OK.
  3. Assign the module, OPCSAMPLE in the area OPC-SAMPLE to a controller and download it.
  4. Once the OPCSAMPLE module is running in a controller the Barcode application can connect to the defined items and interact with the SFC.
    The SFC will loop through the recipe continuously.
  5. In Visual Basic, select Make EXE File.. from the File menu.
  6. Run the Barcode.exe file.

The application may take a few seconds to start up the first time. The DeltaV OPC Data Access Server does not run automatically when the DeltaV system starts up. The DeltaV OPC Data Access Server will start when the first OPC client application issues a CreateObject call. The DeltaV OPC Data Access Server runs as a background process (no window) and will continue to run until DeltaV services are shut down. To see if the DeltaV OPC Data Access Server is running, open the Task Manager in Windows and look at the Process tab. The name of the executable is frsopcdv.exe.
