以下是大概方法，供各位朋友交流参考，不对之处请指正。首先要了解下什么是无协议通讯和MODBUS协议通讯。根据度娘所说：所谓无协议通讯就是说通信网络的两个或多个终端通过通信网络实现数据的传输，而不必遵循共同的规定或规则。Modbus协议是应用于电子控制器上的一种语言。通过此协议，控制器相互之间、控制器经由网络（以太网）和其它设备之间可以通信。此协议定义了一个控制器能认识使用的消息结构,而不管它们是经过何种网络进行通信的。

　　常用全塑电缆规格代号的意义一般常用全塑电缆规格代号排在电缆型号的后面，常用数字表示。（2） 市内用市话全塑电缆的结构（H）凡是电缆的芯线绝缘层、缆心包带层和护套，均采用高分子聚合物塑料制成的，就称为全塑电缆。

　　合格标准为火焰不可蔓延到12英尺高的房间的上部。干线级电缆没有烟雾浓度规范，一般用于楼层垂直和水平布线使用。◎商用级-CM级（垂直燃烧测试VertialTrayFlameTest）这是UL标准中商用级电缆（GeneralPurposeCable），适用安全标准为UL1581。

下图为带动态惯量阻尼器的步进电机暂态特性的步进响应的比较。此种吸振阻尼器不会像反相制动方法那样，在产生超调后才制动，但也不会消除初的超调量。此种动态惯量阻尼器可以改善步进电机高速区域的共振引起的转矩降低，也可以改善高速时的转矩和响应脉冲。利用驱动电路的改善半步进1-2相激磁的情况：阻尼以及定位时，利用2相激磁比1相激磁要好。所以两相步进电机使用半步进驱动的1-2相激磁时，停止相采用2相激磁，阻尼会变好。

For example, zr-djypv zr-djypvp et al. (2) armored (steel belt armored) cables need to add code "22" in the lower right corner of the model, such as: DJYPV22 djypvpppvp22, etc. The cable is mainly used for ac or dc 300V or below and can work normally when 500V or below.
