New HighwayVIEW for Windows Links LabVIEW to Allen-Bradley PLC Series
Programmable Logic Controllers

March 24, 1993 - Austin, TX - Software Engineering Group (SEG-Cambridge,
MA) and National Instruments (Austin, TX) today announced HighwayVIEW for
Windows, a new LabVIEW Virtual Instrument (VI) library used to control and
monitor Allen-Bradley programmable logic controllers (PLCs). With the SEG
HighwayVIEW VI library and network driver, LabVIEW can communicate with
Allen-Bradley PLC-5 and SLC 500-series controllers using the serial port
of a Windows-based PC.

"HighwayVIEW brings the ease and power of LabVIEW to the factory floor,"
remarks Andrew Agoos, president of SEG. "With the new add-on VI library,
you can quickly create displays, panel controls, production management
tools, and statistical quality systems without sacrificing the reliability
or ruggedness of PLCs. With HighwayVIEW and LabVIEW, process engineers and
systems integrators can create their own Windows-based control systems
anchored by Allen-Bradley PLCs and directed by software that is easy to
operate, quick to develop, and very well suited for statistical process
control."

Allen-Bradley provides a vast and complete product line of industrially
hardened PLCs and associated I/O devices. HighwayVIEW drivers communicate
to Allen-Bradley PLC-5 and SLC 500-series controllers using the
Allen-Bradley Data Highway, Data Highway Plus, and DH485 asynchronous
interfaces. The HighwayVIEW package includes a complete library of VIs for
PLC data table access, as well as example programs to upload and download
PLC memory, perform interactive reads and writes, and to graphically
monitor PLC data table activity.
