5.3 Creating a PHD OPC Server Client Application
The PHD OPC Server is designed to be used by any client application implemented to
support OPC Data Access interface standards or OPC Historical Data Access interface
standards. There are numerous existing commercial software products that provide this
functionality; however, you may need to create a custom application to meet the requirements
of an operational environment.
Required expertise
Developing an OPC client application is not a trivial undertaking. You must be familiar with
OPC and the underlying Microsoft DCOM architecture, and should be well versed in the
development of applications in Visual C++ or Visual Basic. There are numerous documents
available that will help you obtain the necessary expertise.
If you are developing an OPC client application that uses the PHD OPC Server, become
familiar with the Uniformance PHD to understand the fundamentals of its implementation and
the services it provides.
Software developer tools
The standard OPC interface definitions and run-time libraries are provided by Microsoft
Corporation on Windows development platforms. Any client application developed using
Microsoft tools and libraries can access data through the PHD OPC Server.
Typically, Microsoft Visual Basic and Visual C++ are used to create a client application that
uses OPC methods to access data from an PHD OPC Server. You can choose from several
commercially available software tool sets to accomplish this task.
