Abstract: The application of SUPCON JX-300 X distributed control system in the process of penicillin fermentation is introduced. In respect to the production technology, an automatic controlling plan is made which include the control of appending stuff 、temperature 、pH value and remove foam. Besides, the system collocation and software configuration methods are explained: the main equipment is JX-300X and the fermentation workshop is equipped with them multiple pots integrated mode. The proposed system has the characters of high safety, high adaptability and convenient operation，and it has been successfully completed in penicillin fermentation process, which can substantially upgrade the degree of automation and improve management level.
