基于Modbus通讯协议实现选矿药剂自动添加装置的网络通讯

Modbus Communication Network Set up and Implementation in Reagent Automaitic Feeder

随着计算机网络、通讯、控制等技术的发展,信息交换沟通的领域正在迅速覆盖从工厂的现场设备层到控制、管理的各个层次。基于现场总线的智能仪表对现场总线技术在我国的推广应用具有非常重要的意义。本文在Modbus现场总线协议的基础上介绍利用S7-300PLC实现药剂自动添加装置的网络通讯过程。

As networks, communications, and control technology development, information exchange communication sector is quickly covering field devices from the factory floor to the control, management at all levels. To promote the application of Fieldbus-based intelligent instrument for field bus technology in China has a very important significance. In this paper, network communication based on Fieldbus Modbus protocol using S7-300 PLC is introduced.
