摘要
目前,工业现场许多一次和二次仪表都带有RS-232/RS-485串行接口,可通过协议转换装置将这些串行设备应用到DeviceNet总线系统中。文中对串行设备和DeviceNet总线协议转换的关键问题进行了分析,提出了基本的解决思路和实现方法。
Currently, there are many primary and secondary instruments with RS-232/RS-485 interface, which can be used into DeviceNet fieldbus system through protocol conversion set. The key problem for protocol conversion between serial devices and DeviceNel fieldbus was analyzed, and the solving thought and implementation method were given.
