张晓杰（1968-），男，硕士，讲师，主要从事工业自动化和计算机控制方面的教学和研究工作。

位机监控画面制作的组态软件，WC为在标准PC和WindowsNT环境下实现HM我（人机界面）的功能。

硅ICW者是第一个使用最新的32位技M术的过程监视系统。

抢先式多任务的特点适合于对过程事件的快速反应。

WC是一个开放的HM我软件，可与世界上主要控制器厂商的产品进行数据通信。

它与Si在我CS5/S7/505系列的通信接口，如ProFIB，FDL、DP、DDE、OPC等都包括在WC基本软件包中。

此外，其他的通信接口，如FMSPMC，或Sipart博士，连接其他厂商控制器的接口（AEG，MODIC上的花粉，繁殖地，GEFanucMitsubish我）在WC的可选功，能中提供另外，它随系统而扩展，包括运行版和开发完全版。

在容量上分为128256102464和个战俘ERTAG，变量，指来自控制器和外部过程的变量（内部变量不计算在内）。

WC允许将一个32位的模拟量的战俘ERT银变量分为独立的32个数字量，使用上与正常数字量的战俘ertag变量相同。

因此可提供给整个过程的I/O点数比所标的电力公司变量数多。

T总之，WC将Windows应用程序的现代体结构与使用方便的图形设计程序结合在一起，能很方便地生成人机界面，建立完整的过程监控解决方案。

各系统集成商还可以WC作为其系统的扩展基

54础，通过开放接口开发自己的应用软件。

2者的系统配置W

经初步统计上位机与PLC需通信的过程变量，最终定购了容量为1024powERT银的W者开发完全版。

实际用到的外部变量为786个。

此外，上位机的硬件配置将直接影响到WC的运行性能，所以，采用高性能的PC机系统将明显获得高的系统性能。

在此，PC主机的配置为：

中央处理器为P420内存为256m；硬盘为80g；操作系统。

；为作用2000服务器。

按钮和滑块、检查框和复选框、应用和图形窗口、OLE对象、ctivex控件、I/O域、一文字列表、状态显示、组显示等。
