摘　　要：本文介绍以三菱PLC作为主站,通过RS485总线与多台艾默生TD1000系列变频器串行通讯,构成高精度变频器调速控制、监控系统。通过详细描述系统的硬件构成,PLC与变频器之间的通讯原理和通讯协议,阐明了该网络控制调速系统与一般模拟量控制调速系统相比的优越性,给出了系统框图以及PLC系统的软件实现方法。This essay introduces the controlling and supervising system of the precise timing control transducer, which is made of the RS485 communication network using Mitsubishi PLC as the main station and multiple Emerson TD1000 series transducer. It describes in detail the hardware formation of the system, the communication principle between the PLC and the transducer and the treaty of the communication. Furthermore, it clarifies the advantage of the network controlling system over traditional similar controlling system, and finally provides the system framework and a software solution for PLC system.
