ASI总线的原理和技术特点

ＡＳＩ总线是一种主从结构的底层网络系统，主机和从机通过２芯电缆可以组成我处拓扑结构的双向数字通信系统。信号和电源共用２芯电缆，信号以开关量为主，通过网关主机可以和现场总线连接ＡＳＩ总线技术成熟、简单可靠、费用较低，很快会成为国际标准。因此在自动化和低压电器系统中会有广阔的发展前途和应用领域。

Principle and Technical Characteristics of ASI

ASI is a lower level master slave mode network system.Bi directional digital signal system of different topologies can be easily integrated by master and slave through two wire cables.Signals and power supply share the same cable.Most signals are binary ones and can be connected to fieldbus via the master gateway.ASI is an uncomplicated,cost effective,flexible and reliable technology,and will become the international standard soon.It will be applied broadly in the automation and low voltage device systems.;
