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 Internet.
Georgetown, Ontario (PRWEB) 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.
Founded in 1995, Cogent Real-Time Systems
provides data connectivity software for professionals with a need to share
real-time data among applications and users. Cogent's customers include the Bank
of Canada, Cadbury Chocolate and the European Space Agency. The company has an
engineering background, with a history of developing real-time applications for
the industrial process control market.
