CIE INTEGRATED SYSTEM FOR THE CPCM (COUPLED PICKLE LINE AND TANDEM COLD MILL) AT DOFASCOS-HAMILTON-WORKS

The CPCM at Dofasco's Hamilton Works (Canada) began commercial product ion in December 1991. This plant is one of the most modern of its kind in the world, combining a pickle line with a tandem cold mill for imp roved productivity and quality. Toshiba Corporation supplied the compu ter, instrumentation, and electrical or CIE integrated control system for this facility. The control system consists of the three major subs ystems communicating over a high-speed LAN (Local Area Network). One o f the main features of the CIE integrated control system is that the c omputer, instrumentation, and electrical control systems are independe ntly allowed efficient and free access to the data running through the LAN's. Other features include an integrated controller for control of both instrumentation and electrical systems and a man-machine interfa ce providing the operator access to data from all three systems.
