摘要
在煤矿很多工控系统中,由于不同厂家生产的仪表、控制器、PLC的通讯方式各不相同,有以太网通讯、RS485通讯、RS232通讯,如何将这些设备实现通讯互联是一个难点问题,本论重点研究利用ModBus协议,实现工业仪表与控制系统之间通讯互联的主要步骤与方法,结合现场实例,给出利用Modbus协议实现通讯互联的完整解决方案。
In many industrial control systems in coal mines,due to the different communication modes of instruments,controllers and PLC produced by different manufacturers,such as Ethernet communication,RS485 communication and RS232 communication.How to realize the communication interconnection of these devices is a difficult problem.This paper focuses on the main steps and methods of realizing the communication interconnection between industrial instruments and control systems by using ModBus protocol.Combined with field examples,a complete solution to realize the communication interconnection by using Modbus protocol is given.
