【摘要】 武钢热轧厂在电动AGC改为液压AGC的技术改造中,GE90-70 PLC与WDPF系统间能否正常通信,是改造方案成败的关键。详细介绍了如何实现这两套异型网(系统间)联网通信的软件、硬件、网络配置。实践证明,VME光纤内存映射网通信技术方案速度快、容量大、可靠性高,是WDPF系统(或MULTIBUS总线)和GE90-70系统(或VME总线)间联网通信的最佳选择。更多还原

【Abstract】 In the technical innovation project,in which the electric power AGC is planned to be transformed into hydraulic driven AGC in the Hot Rolling Mill of WISCO,the key factor for the success or failure of the innovation project is whether normal communications between GE90-70 PLC and WDPF can be carried out.The present paper introduces in detail the software,hardware and network configurations that are indispensable for realization of normal communications between two different type network systems.Practical results show that the technical communications plan of the VME optical fiber internal storage image network,featured by its fast speed,large volume and high reliability is proved to be the best choice for internet communications between WDPF system(or MULTIBUS bus) and GE90-70 system(or VME bus).更多还原
