The advantages of electric cable are more and less. Generally, it is buried in the soil or laid in indoor, ditch, middle, line insulation distance is small, no tower, little, basically no surface space. High reliability. It is less affected by climatic conditions and surroundings, and has high transmission performance and reliability. It has more favorable conditions for the development of ultra-high voltage and large capacity, such as low temperature, superconducting power cable, etc. The distributed capacitance is large. Less work. Less likely.

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.

它们之间的转换关系需要参考ADA模块与设备量程来确定。DA模块它的数字量与模拟信号电压之间的关系如下图：模块端4000量程的数字量对应10V电压信号，按照此关系进行转换。而在设备端变频器频率与模拟量之间的关系为：50.00Hz对应于10v电压信号输入，那么在plc编程中频率与数字量转换的关系就是1数字量=1.25Hz或者1Hz=0.8数字量，加入我们要控制变频器30.00Hz运转，就要向DA模块中写入2400数字量。
