the same control policy and “plug and play”. Devices with the same performance from different vendors can be interchanged.
2.3 Flexible Network Topology
Fieldbus control system can be composed of different network topologies according to complex field conditions, such as tree, star, bus and hierarchical network structure.
2.4 Highly decentralized system structure
Field device itself belongs to the intelligent equipment, has the basic function of the independent automatic control, so as to fundamentally change the architecture of combining centralization and decentralization of DCS, formed a new kind of distributed control system, realize the control function of dispersed thoroughly, improve the reliability of the control system, simplify the structure of the control system. The field bus can maintain the independent normal operation of the underlying equipment after it is disconnected from the upper level network, and its intelligence degree is greatly strengthened.
2.5 Highly intelligent field equipment
Traditional DCS uses a relatively centralized control station, its control station is composed of CPU units and input/output units. Fieldbus control system will DCS control station function completely dispersed to the field control equipment, only by fieldbus equipment can realize the basic functions of automatic control, such as data acquisition and compensation, PID operation and control, equipment self-check and self-diagnosis and other functions. The operator of the system can realize remote monitoring in the control room, set or adjust the operating parameters of the field equipment, and locate and diagnose faults with the help of the self-
