【Abstract】 Programmable Controllers ( PC ) are widely used in various industrial fields. However, it is the first time in China to control a whole coal preparation plant by using PC and com-puter monitering system. A new software design method is suggested in the paper which is quite flexible, efficient and concise. The design method not only reduces the cost of com-puter hardware but also improves system performance.更多还原
