　　在一定条件下，也可用于传输2048Kbit／S以上的数字信号。在一30℃～+60℃的环境条件下，电缆保证长期、可靠的运行。结构导线：铜线直径为、0．40、O．50、O．60、0．70、O．80、O．90mm。

三，LED灯具本身质量不过关，常见问题基板漏电等。解决方案：这个没什么好说的，只能换灯，买质量过关有保障的灯具。四，零线带电，家庭线路零线带电的情况不多。如果是三相电分出来的单相电，偶尔有零线带电的情况，比如三相电压不平衡，线路过长，电流过大等等，都会引起零线带电。解决方案：加装LED防微光保护器，即使有以上各类原因，都可以解决关电后微亮的现象。五，不要使用电子开关，电子开关内部有指示灯，开和关的时候都有指示灯，所以关灯以后开关里还是有微弱电流，也会引起LED灯微亮。

在主站中设立一个“远程I/O缓冲区”，采用信箱结构，划分为几个分箱与每个从站—一对应，每个分箱再分为两格，一格管发送，一格管接收。主站中通讯处理器采用周期扫描方式，按顺序与各从站交换数据，把与其对应的分箱中发送分格的数据送给从站，从从站中读取数据放进与其对应的分箱的接收分格中。这样周而复始，使主站中的“远程I/O缓冲区”得到周期性的刷新。在主站中PLC的CPU单元负责用户程序的扫描，它按照循环扫描方式进行处理，每个周期都有一段时间集中进行I/O处理，这时它对本地I/O单元及远程I/O缓冲区进行读写操纵。
