Kepware Technologies provides free download of OPC client sample code for Visual
Basic, Visual Basic .NET, and Visual C++.
RELEASE: Portland,
ME March 16, 2007 -- Kepware Technologies announces the release of an easier download and install
of their KEPServerEX OPC server with Simulation driver
as well as free sample code including OPC client code
for VB.NET.
The
code samples provided in this
easy download will help developers
who are interested in adding
OPC client capabilities to their
Visual Basic and Visual C++ applications.
Kepware's simple VB OPC client
code follows the code structure
found in the OPC Automation Interface
2.0 specification. Kepware's
code is well commented, demonstrates
how to perform basic connectivity
to a single OPC server and provides
additional recommendations for
expansion of the application.
According to Kepware's Technical
Support Manager Fred Loveless,
"The code examples, with their
internal documentation, provide
very detailed explanations of
commands needed for OPC connectivity.
Although we're happy to assist
our customers this greatly reduces
the support time required to
get them up and running with
custom applications." The complex
OPC client code was written to
provide a robust, full-featured
model for OPC client enabling
your Visual Basic applications.
One of the common problems developers
face is how to connect with multiple OPC servers, add multiple Groups with multiple OPC Items, and keep track of change
events to maintain the high levels
of performance that OPC can provide.
The complex OPC client sample
code provides these capabilities.
Additionally, because no OPC
client is complete without the
capability to perform OPC Tag
Browsing, the complex OPC client
example implements a complete
Tag Browsing interface with filtering.
For
automation professionals unfamiliar
with Kepware, it is worth mentioning
that much of this code has been
available for several years and
has been well received by companies
creating custom applications.
For automation engineers who
already use KEPServerEX but are
new to custom OPC client development,
this example OPC client code
is also provided as part of the
full KEPServerEX product suite
so simply refer to the KEPServerEX
/ Examples folder in the Kepware
Products directory on your computer.
Users may borrow freely from
this code to create their own
OPC client enabled applications.
If our free sample code is helpful
or if users feel we could add
more information, please contact
us with feedback. All sample
code is created for use with
the SimDemo project, a data-simulation
tool included with Kepware's
OPC server, KEPServerEX. The
Simulator driver for KEPServerEX
supports a wide range of data
types as well as Simulation Functions
like Ramp, Random, Sine, and
User Defined.
