摘要
Modbus协议是目前工业化和自动化通信领域应用最广泛的工业通信标准协议之一。由于它的技术开放性、可扩充性和技术标准化优势,使它成为了一个具有通用性的工业通信标准。有了它,不同网络厂商的监控产品系统可以简单可靠地同时接入不同网络,实现系统的集中自动监控、分散控制等功能。基于此,重点讨论了基于Modbus协议的变频风机的优缺点。
Modbus protocol is one of the most widely used industrial communication standard protocols in industrialization and automation communication.Due to its technical openness,scalability and technical standardization advantages,it has become a versatile industrial communication standard.With it,the monitoring product system of different network manufacturers can access different networks at the same time simply and reliably,and realize the functions of centralized automatic monitoring and decentralized control of the system.Based on this,the advantages and disadvantages of the variable frequency fan based on Modbus protocol are discussed.
