【摘要】 介绍了300MN水压机控制系统,描述了该系统的网络构成,通过MPI和PROFIBUS-DP实现系统网络通讯的智能诊断。该功能也可应用于其他使用PROFIBUS-DP的总线系统,以提高总线控制的可靠性以及系统的自诊断能力。更多还原

【Abstract】 The control system of 300MN Hydraulic press and the systematical network constitution have been introduced. The fault di- agnosis of net communication through MPI &PROFIBUS- DP has been realized. This function can also be applied in other bus sys- tem. It can increase the reliability and systematical self diagnostic capability of control system.更多还原
