Graybox OPC DA Auto Wrapper

This software review is for the OPC DA Auto interface which is aimed at providing a user-friendly automation mechanism to already existing OPC Data Access Custom Interface Servers. The design goal is to act as a 'wrapper' for these servers so that users can enjoy the functionality that comes with a custom interface.

With this software, users can expect to find nearly all of the required and optional Interfaces in the OPC Data Access Custom Interface. This means that if the OPC Data Access Custom server supports the interface, the functions and properties at the automation level will work.

However, it's worth noting that automation interfaces do not support optional capabilities in the same way that the custom interface does. In other words, some optional functionality may be omitted when using the automation interface. If this happens, the corresponding automation functions and properties will exhibit some reasonable default behavior.

To use this software, all you need is the Graybox OPC DA Auto Wrapper DLL-module. All the necessary OLE-objects are already implemented in the module. Once you register the module, you'll be able to use any OPC Data Access Server with virtually any OLE enabled programming language including Visual Basic and VBA, among others.

In summary, the OPC DA Auto interface is a great tool for anyone looking to improve the functionality of their OPC Data Access Custom Interface Servers. Its automation-friendly mechanism is user-friendly and ensures that almost all required and optional Interfaces are readily available.
