Abstract Air-condition System plays an important role in drug factory for manufactory environment. In order to realize the high efficiency run of air-condition, a control system is designed using S7-300 PLC. Considering the abnormity of equipment in practice, this paper also gives the method to fault diagnosing. From the system effect in Hanjiang Drug Corporation, we can see that this control system is characterized of security, credibility and easy to maintenance.
