Real-Time Monitoring and Integrated Automation Control in Steel Rolling Plant

This paper mainly presents application of human machine interface (HMI) for real time tracing, monitoring, and operation in steel manufacturing industrial automation system, which are realized by the Programmable Logic Controllers (PLC) to collect process data and transmitted by the integrated computer networking-PROFIBUS DP. In the tracing aspect, one of the newest monitor device-Process Data Acquisition (PDA) implemented by ibaAnalyzer software and watchdog hardware is applied in industry network, whose advanced technology mainly include real time recording the data for various of meters, motors, sensors and some field measure devices else, automatic creating backup files for all recording data, and automatically sending feedback to CPU and HMI operation screen. All equipment can normally and successfully run by using real time monitoring and integrated automation control.
