【Abstract】 Fieldbus Technology, as one of the hot topics in the field of automation control, has been paid lots of attention and efforts on its process of standardization in the last 20 years and the target seems still far away. This paper has made some analysis on the proceeding of Fieldbus technology standardization, based on the study of the existing communication protocols for various fieldbus technology and the practical on-site engineering experiences from the authors in this field. With the pilot influence of CIP protocol, some personal opinion and suggestion on the architecture design of Fieldbus standards have been presented.
