Graybox OPC DA Auto Wrapper
-
Version
1.2
The fundamental design goal is that OPC DA Auto
interface is intended to work as a 'wrapper' for
existing OPC Data Access Custom Interface Servers
providing an automation friendly mechanism to the
functionality provided by the custom interface. The
automation interface provides nearly all of the
functionality of the required and optional Interfaces
in the OPC Data Access Custom Interface. If the OPC
Data Access Custom server supports the interface, the
functions and properties at the automation level will
work. Automation interfaces generally do not support
optional capabilities in the same way that the custom
interface does. If the underlying custom interface
omits some optional functionality then the
corresponding automation functions and properties will
exhibit some reasonable default behavior.
Graybox OPC DA Auto Wrapper is the DLL-module, in
which all of the needed OLE-objects are implemented.
After registering this module, you will be able to use
any OPC Data Access Server with almost any OLE enabled
programming language (Visual Basic, VBA, etc).
