| Fieldbus is a new kind of communication protocol used for the field device and field instruments in the process automation and manufacture automation. The fieldbus node is the intelligence instrument, which replace the single function field instruments. The communication network is integrated with control system. The key of function fieldbus if to replace DCS (Distributed Control System) by the new generation of FCS (Fieldbus Control system). The Process Control System base on Fieldbus is developing very fast and widely used. The configuration software determines the function, reliability and development costing of process control system in great extent, so it is important to develop our own characteristic configuration software to accelerate the progress of domestic technology. In the first part of the paper, I summarized the situation and future of configuration software by comparing the advantages and disadvantages of many software all over the world. At the same time, I summarized the current fieldbus technology and compares the different standard fieldbus. Based on the experiences of foreign excellent software and considering the need of this task in plant floor, I designed graphic configuration software, built the frame of software, and completed the function. The software package consists of the following two large parts: Database Editor~ Graphics zutai software. Graphics zutai software include four small parts: Graphic Editor, Program Design of Dynamic Control, Program Design of Standard Tools, Program Design of Real-time data interface. I also extended my work to connect with the Internet Programming. According to this construction model, I developed each part with Windows and Delphi Visual C++, completed the kernel module, and realized the functions. The paper describe the technical details of programming for each part, which include design ideas, data construction, algorithm and flow.
