| 摘 要： | Modbus协议是一个应用广泛的工业现场总线协议,鉴于其简单、开放、帧格式紧凑等优点,于2008年正式成为我国国家标准。介绍一种通过Cyclone系列FPGA实现Modbus RTU模式的方法,首先给出一个可以通用于Modbus主设备和从设备的协议接口单元,然后基于该接口设计了一个通用的Modbus从设备协处理器。实践证明该方法能够满足工业环境的通讯要求,此外,该方法在其他FPGA上也具有一定通用性和推广价值。

| Abstract: | Modbus protocol is a popular fieldbus,and has become one of national standards in China with easy perfor-mance,widely opening and compact frame format.A method of implementing Modbus RTU protocol based on Cyclone FPGA is introduced.A interface can be used both in Modbus server and client,a Modbus slave coprocessor was designed based on it.The test results show that the design meets the communication requirement of industry environment,and has certain value in other kinds of FPGA. |
