Cascade Middleware Connects Linux and Windows in Real Time
Modular technology allows Linux and Windows applications to share real-time data across a network or the Internet.
Georgetown, Ontario (PRWEB) October 14, 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. Linux
programs can now exchange data in real time with a wide range of Windows
programs, across a network or the Internet.
"Linux and Windows each bring
unique advantages to business and industrial computing," said Mr. Andrew Thomas,
president of Cogent. "We see the benefits of uniting the low cost, reliable,
open environment of Linux with the familiar programs and interface of Windows.
With Cascade Middleware you can run Linux in the back office or shop floor, but
access your data in an Excel spreadsheet, in real time."
Cascade
Middleware uses standard data exchange protocols: DDE, OPC, and TCP. DDE is the
protocol used by Microsoft Excel and other Windows applications; OPC is the
protocol for many industrial processes in Windows. TCP is the protocol for the
Internet and most networks. Cascade Middleware connects Linux and Windows using
the TCP protocol, giving Linux programs direct access to any Windows program
that uses DDE or OPC.
"One obstacle to Linux in industrial applications
has been its inability to access OPC," said Mr. Thomas. "This technology gives
Linux a single interface for the full range of OPC products and drivers in
Windows."
Cascade Middleware was originally developed for process control
engineers using QNX, a real-time operating system, and then made available in
Linux. This release of a Windows version brings real-time data to a wider range
of users, including stock market traders, researchers, and project managers who
use Windows. At the same time, it gives process control engineers a bridge for
data across QNX, Linux and Windows 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.
