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。

交流电机虽然结构简单，但是工作原理其实比直流电机要复杂一点，如果要理解清楚也更加费劲。在交流电机的定子上通上三相对称交流电，如上图所示，定子不动，仅仅通过电流的变化就能产生旋转的合成磁场，这个磁场像一个绕着定子旋转的磁铁。有了这个旋转的磁铁，一切就都好办了，在定子内部随便放一个闭合的线圈，在这个闭合线圈里就会感应出电动势和电流，就会产生电磁力，闭合线圈就会转动起来。也可以这么理解，定子上有一个旋转的磁铁，转子闭合线圈由于感应带电，其实也变成了一个电磁铁，外面的电磁铁在转，就会带着里面的电磁铁转，于是交流电机的转子就转起来了。
