１引言卷接机组主要由卷烟机（Ｍａｋｅｒ）、滤嘴接装机（ＰＡ）和料斗（Ｈｏｐｐｅｒ）三部分组成。由于机组构造复杂、输入输出点多，采用传统的数据通信设计方法，会使整机控制系统显得紊乱，结构不合理，易于发生故障，机器工作的可靠性降低。作为现场信号传输技术，...
1 Introduction The crimping unit is mainly composed of a Maker, a Filter Tipping Machine (PA) and a Hopper. Due to the complex structure of the unit and the large number of input and output points, the traditional data communication design method will make the control system of the whole machine become disorganized, the structure is unreasonable, the trouble is easy to occur, and the reliability of the machine work is reduced. As a live signal transmission technology, ...
