摘　　要：以欧姆龙公司CP1H型号的PLC为应用背景,设计了基于Host Link FINS协议的PLC设备远程监控系统。该文提出了基于串口的远程通信方案,并且详细分析了Host Link FINS协议的结构和指令格式,用MFC实现了监控软件的设计,完成监控软件与欧姆龙PLC的数据通信功能,实现监控软件对PLC的远程监控。经过现场的测试和运行,该监控系统稳定可靠,性能较高。Against application background of the CPIH PLC of Omron Company,to realize the design of remote monitoring system about PLC devices base on the Host Link FINS protocol. This paper puts forward a telecommunication program used in the serial port and analyzes the structure of Host Link FINS protocol and command format in detail as well,additionally finishes the design of upper computer communication module by MFC,and realize the function of communication between upper computer and Omron＇s PLC to meet the need of the upper computer to monitor the PLC devices remotely. Through the test and operation shows,the monitor system was reliability and high performance.
