摘要
本文介绍了PROFIBUS-MODBUS网桥(简称PB-M网桥)在电力系统中的应用。详细讲述了使用PB-M网桥建立PROFIBUS协议到MODBUS协议映射关系的方法,给出了设计思路和实现方法。应用证明PB-M网桥在电力系统中的应用稳定可靠,作为协议转换,总线桥很适合电力自动控制现场使用。
The application of the PROFIBUS-MODBUS bus bridge in the power electrical automatic control system is introduced. The detail methods of establishing mapping relationship from PROFIBUS protocol to MODBUS protocol with PB-M bridge is presented. The design thought and implementation methods are also presented. The practical application proved that PB-M bridge is a reliable and stable equipmentas the protocol transition bus bridge, which is very suitable to be used in power electrical control system.
