Development of Communication Protocol Conversion Equipment Based on Embedded MCU and RTX51

Using the embedded multi-MCU and high-speed dual-port RAM data sharing technology, communication protocol conversion equipment based on embedded multi-MCU and real-time multitasking operating system RTX51 has been researched and developed, which adopts RS232 or RS485 communication interfaces for lower machines such as data acquisition I/O modules, smart intelligent instruments and so on. Then, the data are transferred by Ethernet communication interface to the remote monitoring systems such as DAS or DCS. The functions of industrial communications network relaying and protocol conversion will be realized, therefore, the serial devices of device layer can be easily connected to the networked control layer.
