3楼 回复本楼那你用C语言按MODBUS的通信协议格式来写一段C的程序不就OK了,下位机本来就支持MODBUS从站的通信,你不是用来下载程序吧,如果不是,这是最好的办法呀.

4楼 回复本楼是支持modbus,但是要求是上位机用C#写tcp/ip的tcpclient端，plc做下位机写tcpserver端用c的socket库，功能程序都已经写好transfer到plc里，现在要做个上下位的通讯。上位机客户端发命令，下位机做服务器端接收并解析后给反馈信息给上位机。automation studio里有ASTCP库和ethsocket库，感觉好像要用ASTCP。知道您好像特别熟悉贝加莱PLC，可不可以向您请教请教这方面的知识？因为要做，又不是特别懂，先谢了。
