the so-called DCS system. Fieldbus is born in this situation.
Fieldbus technology and its characteristics
The fieldbus technology is developed in the late 80 s the scene of an advanced industrial control technology, it combines digital communication technology, computer technology, automatic control technology, network technology and intelligent instruments such as a variety of technical means, fundamentally breaks through the traditional “point to point” the limitations of analog signal or a digital analog signal
control, A fully decentralized, fully digital, intelligent, two-way, interconnection, multi-variable, multi-point communication and control system. Fieldbus is a digital, bidirectional and multi-branch communication network connecting intelligent field equipment and automation system. Its foundation is intelligent instrument. The smart instruments scattered in various industrial sites are connected by a digital Fieldbus and together with controllers and monitors in the Control room constitute the Fieldbus Control System (FCS). By following certain international standards, fieldbus products from different manufacturers can be integrated in the same set of FCS, with interchangeability and interoperability. FCS further devolves the control function of traditional DCS to the field intelligent instrument, which completes the functions of data acquisition, data processing, control operation and data output. The data of field instruments (including the collected data and diagnostic data) are
