两者之间经过一条通信线路(通常是RS422)联系在一起,使得它们得以共享所有的信息资源。也就是说,PLC中所有供用户使用的软件资源,即数据寄存器、状态寄存器、定时器、计数器等,在GOT中也有完全相同的一套镜像。其中任何一台计算机,无论因何种原因,以何种方式,改变了任何资源中的任何信息,都会在另一台计算机中立即被复制。也可以说,因为两者之间的即时通信,使得两者的信息资源互为镜像。这种既独立又分工的协作关系,使得它们能够出色地完成共同的任务。

10,电导率:又叫电导系数。是衡量物质导电性能好坏的一个物理量。其数值大小是电阻率的倒数。用字母γ表示,单位为S/m(西/米)。11,自感:当闭合回路中的电流发生变化时,由这个变化电流所产生的、穿过回路本身的磁通随之发生变化,在这回路中将产生感生电动势,这种现象称为自感现象。这种感生电动势叫作自感电动势。穿过回路所包围面积的磁通与产生此磁通的电流之间的比例系数,叫作回路的自感系数,简称自感。其数值等于单位时间内,电流变化一个单位时由于自感而引起的电动势,用字母L表示,单位为H(亨利)。
