Modbus/TCP协议在工业控制中已经得到了广泛的应用,为了进一步提高监控系统的通用性和井下远程数据的传输能力。深入地研究了Modbus/TCP协议,成功的将LwlP协议栈移植到ARM中,研制了支持Modbus/TCP协议的监控分站,同时还兼容Modbus/RTU协议,最终实现了与MCGS的连接。
Modbus / TCP protocol has been widely used in industrial control, in order to further improve the versatility of monitoring system and underground remote data transmission capability. In-depth study of the Modbus / TCP protocol, the success of the LwlP protocol stack ported to ARM, developed a monitoring sub-station that supports Modbus / TCP protocol, and also compatible with Modbus / RTU protocol, and ultimately the connection with the MCGS.
