Distributed Control System Based on Industrial Ethernet and FieldBus

Distributed control system (DCS) is based on industrial ethernet and fieldBus. On the basic construction, the system extends special function stations, communication networks for produce management and information disposal, fieldBus networks that realize locale instruments and executing agency’s numeralization. Control stations process directly carries out locale I/O data sampling, information alternation, control operation and logic control, completes real-time control in the whole industry process and realizes kinds of I/O interfaces. In the field bus system CAN changes system locale signal lines’ connection mode and makes DCS numeralization in locale measurements and control executions.
