| Fieldbus technology is popular in industrial control fields today , which is the full-digital , bi-transmission and multi-branches structure communication network , which connect the intelligent field devices and the automatic system . But at present, the Fieldbus technology is just placed in the developing stage, modern process control system transition from the distributed control system (DCS) to fieldbus control system (FCS). The current-fieldbus converter designed in this thesis resolved the compatibility of the traditional devieces and the FCS , this carries the great importance to expand the application of the FCS. Both of the hardware design and the software development of the converter are introduced in detail here , including the selection of the components , the design of the concrete circuit , programming and debugging Last of all, probed the problem coming from the design and bringed up suggestion of the further satisfactory and expanding of the converter. |
