本文在介绍欧姆龙公司C系列PLC的DeviceNet总线系统的基础上,以多级传送带系统为控制对象,建立了DeviceNet主、从单元构成的通信网络,利用OMRON DeviceNet Configurator软件配置网络参数并下载到主单元中,实现了单台可编程序控制器对系统40个节点的实时通信控制,节省了大量布线费用。
Based on the introduction of the DeviceNet bus system of C series PLC of Omron Corporation, this paper takes the multi-level conveyor system as the control object and establishes the communication network consisting of the master and slave devices of DeviceNet. The network parameters are configured by OMRON DeviceNet Configurator software and downloaded to the master unit In the realization of a single programmable logic controller for the system 40 nodes in real-time communication control, saving a lot of wiring costs.
