探伤加速器控制系统采用多台小型PLC,为避免长距离及强电磁环境下的干扰,采用基于TCP/IP的光纤网络通讯。实现的功能有:1)可同时对每个PLC进行编程操作、在线调试;2)可实现任意两个PLC之间的数据交换;3)可实现上位机的通讯需求。对于网络可能的堵塞或模块故
Detection accelerator control system uses multiple small PLC, in order to avoid long distance and strong electromagnetic environment interference, using TCP / IP-based optical fiber network communications. Achieve the functions are: 1) Simultaneous programming of each PLC, online debugging; 2) to achieve any two data exchange between PLC; 3) to achieve the communication needs of the host computer. Possible network congestion or module
