Delphi Opc Client Software Code Must Be

Too many lines of error-prone code must be written to achieve a simple goal reading or writing a value.

QuickOPC is unbelievably easy to use - here is an Object Pascal example which reads and displays OPC data from a common OPC Data Access server.

Using complex heuristic algorithms to optimize itself on the fly, it provides the most efficient, fastest access to the OPC data.

The Delphi example below shows how subscribe to changes of a single item and display the value of the item with each change.

Code example is available in the documentation, and installed with the product.

Installing QuickOPC or its Options does not change system settings.
