Design of Control System of Straight Line Wire Drawing Machine Based on Profibus-DP

In the paper the author introduces a synchronous speed control system of straight line wire drawing machine with the six heads based on Profibus-DP, in which the SIMATIC S7-300 PLC was used as the master controller. This paper focuses on discussion about the hardware structure and the controlling principle of the variable frequency speed control system, the realization of communication of the controlling system and the software designing flow. The application results indicate that the controlling system has met the designing requirement and proved its practicability and popularization value.
