According to the construction of current coal mine monitoring and control systems in China, the paper pro- poses three kinds of applicable schemes of integrating PLC and DCS systems with field bus technology to digitize the system and to improve the flexibility and extent of the system. Essentially, the paper introduces the integration of FCS on I/O layers. Based on a real coal mine safety-monitoring and control system applied with a CAN field bus, the major technology of system relays and extensions is discussed. We believe that one of the most applicable methods is cur- rently replacing the connection between function-stations and field-sensors with a CAN bus on I/O layers for system integration.
