OPC Data Access Explorer

(To be removed) Explore and exchange data with OPC Data Access servers

Support for the OPC Data Access (DA) standard will be removed in a future release. Instead use OPC Unified Architecture (UA). See Compatibility Considerations.


The OPC Data Access Explorer allows you to graphically browse the contents of an OPC server, view server item properties, and create and configure OPC clients, groups, and items in the toolbox.

After browsing, discovery, and configuration, the app allows you to:

  • Read and write OPC data.

  • Configure and start a logging session, and export logged data to the workspace.

  • Export clients, groups, and items to the workspace, to a MAT-file, or as an OPC session file which you can import into the app at a later stage.
