Conclusion
At this point, all of the basic steps involved in building and testing an OPC project have been discussed. Users are
encouraged to continue to test various features of both the server and the OPC Quick Client for greater understanding
and comprehension. For more information on the OPC Quick Client, refer to its help documentation.
If the basic terminology and concepts are understood, users can begin developing their OPC application. If using Visual
Basic, please refer to the supplied example projects. These two projects provide both a simple and complex example of
how OPC technology can be used directly in Visual Basic applications.
New Channel - Name
This server supports the use of simultaneous multiple communications drivers. Each protocol or driver used in a project
is called a Channel, which refers to a specific communications driver. A server project can consist of many channels,
each with either unique communications drivers or with the same. A channel acts as the basic building block of an OPC
link. Its properties control parameters such as communications port, baud rate and parity.
In a server project, each Channel Name must be unique and can be up to 256 characters long. Although using
descriptive names is usually a good idea, some OPC client applications may have a limited display window when
browsing the tag space of an OPC server.
Note: The channel name entered will be part of the OPC browser information.
New Channel - Driver Page
After a name has been entered for the new channel, a communications driver must be selected from the "Device
driver:" drop-down list. The drop-down list's contents depend on the communications drivers currently installed on the
PC. The list will contain the drivers available for use in the server project.
