依靠西门子S7中FB41连续控制,FB42步进控制及FB43脉宽调频控制来实现工业工程中的自动及半自动控制理论,从而达到工业生产基础中更高一级的智能化。本文只针对FB41连续控制做理论与实践。
Relying on the FB41 S7 FB42 Siemens continuous control, step control and FB43 pulse width modulation control is achieved in industrial engineering automatic and semi automatic control theory, intelligent based industrial production so as to achieve a higher.
