Description
系统主机采用SIEMENS公司SIMATIC S7 414-2DP作为控制站主机,并采用PROFIBUS DP分布式I/O将现场I/O站与控制站连接起来,HMI系统采用SIMATIC WINCC V4.01,并利用3DS等三维图形制作工具绘制出三维动态工艺流程图.系统采用客户机/服务器模式,使得现场操作站既完成现场操作功能,同时又作为服务器供管理人员查看现场生产状况.该系统在合肥利华10万吨洗衣粉扩产改造工程中得到应用,并于1999年3月17日正式投运,系统一直稳定运行,配料精度高,设备联锁保护合理,受到厂方的一致好评,本文主要以合肥利华为例,介绍SIMATIC控制系统在洗涤剂生产线上的实践与应用.
