摘　　要：介绍了在天然气分布式供能系统中,用来实现燃机(MT250)和控制系统(OmronPLC)之间通信的Modbus协议宏。重点阐述了Modbus RTU通信协议的定义格式、Omron协议宏转化软件的通信配置方式以及地址映射等内容。由此得出通过协议转化,可对燃机的转速、功率因数、温度等运行参数进行监视和控制。协议宏的应用使分布式供能系统运行稳定、实时性高,对同类工业应用具有一定的参考价值。The Modbus protocol macro for implementing communication between gas turbine MT250 and control system Omron PLC in natural gas decentralized energy system is introduced. The definition format of Modbus RTU communication protocol, communication configuration mode of Omron protocol macro transferring software, and the address mapping are described respectively. It is proposed that through protocol transformation, the operating parameters of gas turbine, such as rotating speed, power factor, and temperature can be monitored and controUed. The application of protocol macro makes the decentralized energy .system running stably with good real-time performance. It is worth to be applied in similar industries.
