Flame-retardant cables are characterized by a delay in the spread of flame along the cable so that the fire does not expand. Because of its low cost, it is a kind of cable widely used in fireproof cable. Under the condition of single cable or into a bunch of laying, cable to know when the spread of flame can be controlled within a certain range, so it can avoid fire spreading combustion and lining major disasters, which cable line of fire prevention level.

在这一过程中,需要注意的地方就是检查电源,1确保回路没有短路。2确保强弱电没有混合到一起;因为PLC电源为24v,一旦因为接线错误导致220V接进PLC里,很容易将PLC或者拓展模块烧毁。检查PLC外部回路,也就是俗称的“打点”电源确认完毕后送电,测试输入输出点,这就是俗称的“打点”,测试IO点需要挨个测试,包括操作按钮,急停按钮,操作指示灯以及气缸及其限位开关等等,具体方法是一人在现场侧操作按钮等,另一人在PLC测监控输入输出信号;对于大型系统应该建立测试表,即测试后做好标记。

若RI=0、SM2=1,则只有停止位为1时,才有上述结果。若RI=0、SM2=1,且停止位为0,则所接数据丢失。若RI=1,则所接收数据丢失。无论出现那种情况,检测器都重新检测RXD的负跳变,以便接收下一帧。方式方式3方式2和方式3是9位异步串行通信,一般用在多机通信系统中或奇偶校验的通信过程。在通讯中,TB8和RB8位作为数据的第9位,位SM2也起作用。方式2与方式3的区别只是波特率的设置方式不同。
