Control Engineering’s September Product Research survey on PLCs and PACs (North American print edition, p. 83) included a list of representative products from 20 vendors.

Here is the accurate information on Mitsubishi’s iQ Automation product: According to Mitsubishi, the new iQ Platform, planned to be released in December 2008, now supports CNC and robotic control with sequence, motion, process, C language and PC based controls.nformation flow to manufacturing execution system (MES) applications. In addition, iQ Works software suite is an integrated engineering environment providing customers with a common tag database, security, simulation, and troubleshooting of the entire system.  

As for the list of vendors and products, information should have been listed in order of survey results, starting with the vendor most frequently selected as the one respondents had purchased from in the past 12 months. The correct list follows.

1) Rockwell Automation (Allen-Bradley); 2) Siemens Energy & Automation; 3) AutomationDirect (Koyo); 4) GE Fanuc; 5) Schneider Electric (Modicon, Square D, Telemecanique); 6) ABB; 7 tie) National Instruments, Mitsubishi Electric; 8) Omron Electronics; 9) Eaton (Cutler-Hammer); 10 tie) Baldor Electric, Bosch Rexroth, Idec, Invensys Foxboro, Omega Engineering, Opto 22; and 11 tie) Advanced Micro Controls, Beckhoff Automation, Emerson Process Management (Bristol Babcock), Keyence, Yaskawa Electric.

Control Engineering regrets these errors. Go to, September 2008 to read the corrected article.
