摘要
介绍新疆众和热电联工程全厂辅控系统的设计原则、系统结构、组网方式等,着重介绍MB系列PLC具有数据通信、流程图编程、自定义功能等特点及其在工程中的应用,为其他DCs工程建设提供参考。
The design principles£-system structure and netstream of Zhonghe cogeneration engineering in Sinkiang are introduced in this paper,and more emphasis are paid to the data communication and flowcharts programming and user defined block of MB series PLC,as well as its successful application in the engineering.The valuable experience cumulated in the project could also be taken as a good reference for the other DCS engineering in future.
