In "Improving Safety in Process Control" in Control Engineering September 1998, an incorrect web site address for the American Institute of Chemical Engineers was listed on pgs. 56 and 84. The institute's correct web address is www.aiche.org .
A report on the BIAS trade fair in Control Engineering International January 1997 included ORSI's introduction of CUBE-DCS, a soft PLC/soft DCS package with IEC-1131-3 environment, embedded Windows NT real-time kernel, hot backup, and open I/O devices on standard fieldbus. As a result, the table of contents in Control Engineering July 1998 should have referred to WizCON's WizDCS as "New SoftDCS reaches market."
