| 摘 要： | 磷酸生产过程自动监控是基于PLC的集散式控制系统。系统由工控机和PLC组成，对生产过程进行全程控制和管理。工控机通过监控画面对PLC进行参数设置，接受参数后PLC执行闭环控制。通过Modsoft软件梯形图语言对PLC编程、程序管理，实现联机调试、在线程序维护及离线程序开发。使用组态软件Intouch7.0设计各种监控画面。计算机与PLC间采用Modbus Plus协议，监控画面采集通过DDE协议。该系统灵活配置，控制可靠，编程简单且成本低。

| Abstract: | The automatic monitoring for the phosphoric acid production process bases on distributed control system of PLC The whole process was controlled and supervised by this system, which consists of PLC and industrial control computer The industrial control computer gives reports for the PLC, and the PLC executes closed-loop control after it accepts the parameters The software Modsoft performs the functions of programming ladders and managing programs, debugging and maintenance online, development offline All sorts of monitor displays are designed using the configuration software INTOUCH7 0 The Modbus Plus protocol was employed between computer and PLC while the monitor display collects data with DDE protocol This system has the merits of flexible setting, reliable controlling, simply programming and low costing |
