The Data Access Automation (DA-Auto) specification defines a standard Microsoft Visual Basic 6.0 (VB6) compatible interface for the Data Access specifications.
The DA automation specification is not intended to be implemented as a standalone server. Instead, the specification should be implemented by a wrapper that can connect to any standard Data Access (DA) server.
The OPC Foundation provides a wrapper reference implementation that is repackaged and distributed by many member companies. Non-members who wish to use the wrapper provided by the OPC Foundation must contact the vendors of the OPC products that they are already using. |
