摘要
介绍了以上位机Wincc和下位机S7-200系列PLC为核心的横幅定量控制系统的设计。采用OPC技术有效的将QCS系统和横幅控制系统连接起来。根据工艺特点和生产要求,采用步进电机控制唇板的开度,有效地控制了横幅定量。重点论述了步进电机的控制方法和上位机的通信与监控功能。实际应用表明,该系统控制精度高,操作简洁方便,工作稳定可靠,能将横幅定量误差严格地控制在范围之内。具有推广价值。
The design of CD base weight control system based on wincc and S7-200 series PLC was proposed.The CD base weight control system is connected with the QCS(quality control system) system by means of OPC technology.According to the technical characteristics and productional requirements,the CD base weight is controlled effectively by using stepper motor control headbox′s lip.Focuses on the stepping motor control method and the host computer communication and monitoring functions.The practical application shows that the control system has high precision,stability,reliability,and convenient operation.The error of CD base weight can be also strictly controlled within the range.And the system has great promotional value.
