SCADA control systems in integrated steel plants

Supervisory control and data acquisition (SCADA) systems have been in existence for a number of years now, They are employed in various applications which involve the simultaneous acquisition of large amounts of data, real-time processing, display and supervisory control. SCADA based controllers have been incorporated in integrated iron and steel plants in two packages-one to meet the requirements of SCADA control for electricity supply systems and a second for gas/heat, water supply and metallurgical facilities. Computer-based systems for SCADA help control system operators to achieve real-time data acquisition, processing, display and control of data pertaining to large process environments. Systems engineering techniques provide solutions by optimally configuring state-of-the-art hardware and appropriate software. Aspects of expansion and maintenance are given due regard to enhance the useful life of such control systems
