Cascade Middleware Connects QNX and Windows in Real Time
Modular technology allows QNX and Windows applications
to share real-time data across a network or the
Georgetown, Ontario (October 15, 2004) Cogent Real-Time Systems, providers of
real-time data connectivity software, announced the release of
new versions of their Cascade DataHub and Cascade Connect middleware
products. QNX programs can now exchange data in real time
with DDE or OPC enabled Windows applications, across a network
or the Internet.
QNX is a real-time operating system known for its
microkernel architecture and interprocess communication. The
Cascade DataHub for QNX uses either TCP or the native
send/receive/reply protocol to collect and distribute data among
QNX programs. The Windows version of the Cascade DataHub can use TCP,
DDE, or OPC to establish client connections. The DataHub
bridges the gap between QNX and Windows using a standard TCP/IP
connection, which means data can be shared between applications
across a LAN, WAN or Internet connection.
"QNX gives solid real-time performance, but most of the
world is using Windows," said Mr. Andrew Thomas, president of
Cogent. "So why not have them both? With Cascade Middleware
you can run hard real-time applications in QNX, and still get
access to data from any DDE program in Windows, as well as the
full range of OPC products and drivers."
Cascade Middleware products are designed to treat each
participating program or process as a modular unit. Any
application can be connected or disconnected at any time,
without disruption to the rest of the system. Programs can send
or receive data synchronously or asynchronously, using
read/write or publish/subscribe models of communication.
QNX programs interact with the Cascade DataHub through the
Cogent API, which includes utilities, libraries, and functions
for writing custom interfaces. In Windows no programming is
necessary, though an API is available for those who wish to
create custom applications.
