Visual FoxPro

Are you having difficulties incorporating the OPC data into your Visual FoxPro solution? Need to do it quickly and in quality? If so, QuickOPC-COM comes to the rescue.

QuickOPC-COM is a set of components that simplify the task of integrating OPC into applications. Reading a value from OPC Data Access server, or writing a data value can be achieved in just one or two lines of code!

QuickOPC-COM is a radically new approach to access OPC data. Traditionally, OPC programming required complicated code, no matter whether you use OPC custom or automation interfaces. OPC Server objects must be instantiated, OPC Group objects must be created and manipulated, OPC Items must be added and managed properly, and subscriptions must be established and maintained. Too many lines of error-prone code must be written to achieve a simple goal – reading or writing a value.

New: QuickOPC can now connect to OPC UA (Universal Architecture) servers.

Key Features (OPC "Classic" Products)

Code Samples

QuickOPC is unbelievably easy to use - here is a Visual FoxPro example which reads and displays OPC data from a common OPC server:

PROCEDURE Click oEasyDAClient = CREATEOBJECT("OPCLabs.EasyDAClient.5.0") MESSAGEBOX(oEasyDAClient.ReadItemValue("", "OPCLabs.KitServer.2", "Simulation.Random")) ENDPROC

Do you think it can be any simpler? But the simplicity is not the only advantage; the component is also very powerful. Using complex heuristic algorithms to optimize itself on the fly, it provides the most efficient, fastest access to the OPC data.
