Step7项目立的过程.doc

Step7项目建立的过程 新建项目： 1、运行Step7：双击桌面快捷方式图标,运行STEP7，弹出新建项目向导。 2、单击上图“取消”按钮，在项目管理器中执行“文件/新建……”菜单命令新建一个项目： 3、在弹出的新建项目对话窗口中给项目命名并确定其保存路径 4、“确定”后出现如下的管理界面 在项目中建立站点， 5、建立站点有两种方法： 方法一：右击项目管理器中的项目名称，在弹出的右键菜单中选择“插入新对象”、/下面的某个站点。本实验先建立一个S7-300站点。 方法二：在管理器界面菜单中选择“插入/站点/……”，如下图选择一个站点即可 执行菜单命令后，即生成一个S7-300的站点， 为方便识读，给站点重新命名： 为新站点进行硬件组态 4、下面即为站点硬件组态界面 5、打开300站点的硬件目录 6、先放置机架 7、分别在机架的12槽旋转电源和CPU，如果有扩展机架则在第3槽放置IM模块，否则第三槽留空，从第四到第11槽可以放置除电源、CPU、IM模块外的其它模块，本实验放置信息模块SM。 urban area 2.5.2 Yibin city in Yibin city, according to resource and environment characteristics Urban population and urban spatial distribution, spatial distribution of industries, major infrastructure Corridor layout, combined with the future development trend of synthetic judgments, planning, urban spatial structure of urban system can be summarized as: a pole along the two axes. A refers to the metropolitan area along the Yangtze River, is the core area of the development of the city. Plans to build for the Yangtze River economic belt on the pillar, advancing along the ... Guanghe River, Yiliang, prestige of the external cohesion of zhaotong, Yunnan, internal connecting Yibin city to the North. The Sichuan-Yunnan-Guizhou border area of Yibin, in the city of zhaotong, liupanshui three, zhaotong city, the most populous and most extensive regions, the most economically backward, to the North in Wumeng mountain area of yanjin, shuifu, suijiang counties radiation power is relatively weak. Yibin city and infrastructure in such areas should be strengthened and docking, extending southward to public services, promote the development of mineral resources in Northeast Yunnan, expand our economic hinterland, driving synchronous lifting in Sichuan-Yunnan-Guizhou border area. This urban axis with mineral resource advantages, focus on the development of advanced technology, comprehensive utilization of resources of higher energy, new building materials, chemical industry, developing new energy and mining towns.
