Abstract

Based on Industrial Ethernet, PLC and Industrial Computer, Monitoring and Control System of Underground Coal Gasification (UCG) were developed. Distributed measured sensor signals and complex monitoring tasks are realized by a PLC and an Industrial Computer. Star topology network is used. The connection between Monitoring system and PLC is realized by an industrial Ethernet module. The solution in laboratory condition appears reliability and quick data exchange was realized between PLC and Monitoring system.
