Control AEG/Modicon PLCs With New BusVIEW Software For PCs and Macintoshes

October 12, 1993 -- Austin, TX-The Software Engineering Group (SEG -
Cambridge, MA), a member of the National Instruments Alliance Program,
announced today the new BusVIEW software that links Windows-based PCs and
Macintosh computers running LabVIEW to AEG/Modicon PLCs. Process engineers
and systems integrators can use BusVIEW in process monitoring, operator
control, statistical process control, data collection, or recipe
management applications.

About BusVIEW 

BusVIEW simplifies process control applications that use AEG/Modicon PLCs.
System developers first construct LabVIEW panels using built-in graphics
controls and indicators, then select appropriate BusVIEW PLC functions for
the LabVIEW diagram from a pulldown menu. Users then connect the BusVIEW
icons to the rest of the diagram to quickly create LabVIEW man-machine
interfaces (MMIs) that supervise the PLCs. With BusVIEW, LabVIEW can read
and write discrete and analog values stored in AEG/Modicon 984, 884, 584,
484 and 384 Series PLCs. BusVIEW handles both ASCII and Remote Terminal
Unit (RTU) framing methods of the Modbus protocol. BusVIEW is compatible
with any devices that conform to the Modbus Protocol Standard published by
AEG/Modicon.

"Links to popular PLCs bring the ease and power of LabVIEW to the factory
floor," says George Stein, Vice President of Engineering at SEG. "BusVIEW
joins HighwayVIEW (SEG's link to Allen-Bradley PLCs) in making it easier
than ever to produce a cost-effective MMI that leverages off of the
flexibility and power of the LabVIEW graphical programming language."

System Requirements 

BusVIEW for Macintosh requires a Macintosh LC Series, Powerbook, Quadra,
Centris, or any Macintosh II Series computer running System 6.0.5 or
later, 8 MB RAM, and LabVIEW Version 2.1 or later. BusVIEW for Windows
requires a 486 PC or higher with 8 MB RAM; Microsoft Windows 3.1 or later,
and LabVIEW Version 3.0 or later.
