ROCKWELL'S ALLEN-BRADLEY BUSINESS COMPLETES $25 MILLION PROJECT FOR NUCOR YAMATO STEEL

 MEQUON, Wis., Oct. 28 /PRNewswire/ -- Rockwell International Corporation's (NYSE: ROK) Allen-Bradley business unit, a leader in industrial automation and control, announced completion of a $25 million order for Nucor Yamato Steel, Blytheville, Ark., for a plantwide integrated control system. The contract represents the largest single system order in the history of Allen-Bradley. The new $200 million plant began casting the world's largest steel beam blanks on May 17, 1993, and rolling large section wide flange beams on July 26, 1993, two months ahead of schedule.
 As the plant's lead controls contractor, Allen-Bradley integrated the control system for the continuous caster, wide flange beam and finishing area. In addition, the system provides a way to operate the process in an automatic mode. The control system includes 68 Allen- Bradley AC drives, comprised of either Bulletin 1336 or 1352 AC drives, and 71 Bulletin 1395 DC drives with 19 PLC-5(R) programmable controllers to facilitate accurate and smooth control of the process.
 Data Highway Plus(TM) and Remote I/O streamline communications of the programmable controller systems throughout the plant. Common architecture of the products eases communications among plant sections and contributes to smooth installation and operation.
 Operators can interface with the system via 17 consoles, nine of which are PanelView(TM) operator interface terminals. The remaining eight are Allen-Bradley T60 Industrial Workstations.
 Allen-Bradley was able to complete system start-up and installation ahead of schedule, due in part to the metals industry experts dedicated to the project. Allen-Bradley engineers from multiple product divisions were involved from initial design meetings throughout the start-up process.
 "The job Allen-Bradley completed for Nucor Yamato II jumbo beam mill is by far one of the best jobs I have experienced in my 32 years in the construction industry," said Norman Maero, Nucor Steel construction manager.
 Allen-Bradley, headquartered in Milwaukee, is a worldwide leader in the manufacture and sale of industrial automation controls and systems. It is a unit of Rockwell International Corporation, a multi-industry company applying advanced technology to a wide range of products in its electronics, aerospace, automotive and graphics businesses.
