  接地引出线要求采用我镀锡编织铜线,和电缆铜带连接时应用铬铁锡焊,不宜用喷灯封焊,以免烧损绝缘。 ③三相铜带屏蔽应分别与地线相连,注意屏蔽接地线和钢铠接地线应分别引出,相互绝缘,焊接地线的位置应尽量靠下。

使用程序状态功能监视数据块点击数据块工具栏上的监视按钮,自动切换到“数据视图”显示方式,数据块内的存储单元在线的数值在实际值列中显示,程序状态被激活后,不能切换“声明视图”方式。结构的生成和使用结构的生成可以在数据块中或逻辑块的声明表中定义结构,下面介绍在数据块中定义的方法,在上面DB3数据块中,再定义一个结构,名为stack的结构由3个不同数据类型的变量组成。如下图所示:在“ARRAY”下面的INT,按回车键,在该单元下面生成一个空白行,在名称输入stack,在类型列单元点右键选择复杂数据类型,选择STRUCT,(也可以直接输入STRUCT),按回车后再改行下面出现新的行,按如图输入。

  1952年,瑞典在北部发电厂敷设了380千伏超高压电缆,实现了超高压电缆的应用。到80年代已制成1100千伏、1200千伏的特高压电力电缆。我厂引进先进设备,先进技术。电力电缆的基本结构由线芯(导体)、绝缘层、屏蔽层和保护层四部分组成。

也就是说UDT的作用就是方便编程者的,对于程序的运行而言不是必需的.从数据类型的角度来说,UDT甚至不会被PLC直接接受.大家看西门子S7-300的程序的上传就知道了,将一个带有UDT的程序下载到PLC中,然后新建一个PLC,上传程序,在传上来的程序中你是找不到UDT的.UDT更像是对DB结构的注释!下面教大家如何在博途里使用UDT.在项目树中PLC数据类型中双击添加新数据类型对新建的数据类型重命名,如UDT在UDT中添加要用的变量,编译保存。
