PLC/PAC product research information revised
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. The information from Mitsubishi Electric Automation was incorrect, and the list of vendors was in the wrong order.
Following is the accurate information on Mitsubishi’s iQ Automation product: According to Mitsubishi, the new iQ Platform, planned for release in December 2008, now supports CNC and robotic control with sequence, motion, process, C language and PC-based controls. This flexibility allows customers to choose the best-suited mix of control disciplines for their applications and place them on a single platform. iQ Platform provides customers with horizontal integration to support legacy third-party control systems; vertical integration provides real-time information 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.
