摘要
日立三电控制系统采取了信息网、控制网、设备网三级通讯结构。传统的设备网不支持Profibus-DP网络通讯,无法与Profibus-DP接口的设备进行通讯。为了解决日立三电控制系统与Profibus-DP网络之间通讯的问题,国内某酸轧机组通过运用Anybus-M接口技术,开发主、从站通讯接口模块和编制通讯接口程序,建立了设备网与Profibus-DP网络的连接。重点阐述Profibus-DP网络应用技术的实施过程,该系统投入运行后,具有通信速度快、开放性好等优点,提高了网络的兼容性,这也是Profibus-DP网络在日立三电控制系统首次应用,对工程实践具有现实指导意义。
The application of the Profibus-DP network to Hitachi EIC control system with a three-level communication structure, i.e. , information network, control network and device network is dealt with. To solve the communication problems between Hitachi EIC control system and Profibus-DP network, utilized the Anybus-M interface technology is used in the domestic PL-TCM. The master and slave station communication interface module and program are developed. The network connection between the device network and Profibus-DP is establishing. The implementation process of the Profibus-DP network application technology is presented. The system has the quickly communication speed, openness ability. The network compatibility is improved. It is the first successful application of Profibus- DP network to Hitachi EIC control system, and has a reality guide for project practice.
