摘　　要：玻璃珠供料装置作为高放废液玻璃固化工程的核心设备之一,在调试过程中报"存储打印故障",自动流程中止,且无法按照《设备维修手册》进行复位,影响工艺系统稳定运行。通过对用户程序逻辑、通信组态及连接、硬件模块等方面的逐步排查分析,确定该故障与用户程序逻辑不严谨有关。为保证玻璃珠供料装置的连续可靠运行,可通过屏蔽打印功能、在线监视程序并手动复位相关变量或修改用户程序进行自动复位3个角度解决问题。该文可为采用西门子S7-300通过CP340模块实现外围设备串行通信的控制系统的故障排查及处理提供一些参考。As one of the core equipment of high level liquid waste(HLW)glass solidification project,the glass bead feeding device reported"storage and printing failure"during commissioning,which automatically stopped the process and could not be reset according to the equipment maintenance manual,which affected the stable operation of the process system.Through the gradual investigation and analysis of user program logic,communication configuration and connection,hardware module and other aspects,it is determined that the fault is related to the user program logic is not rigorous.In order to ensure the continuous and reliable operation of the glass bead feeding device,the problems can be solved by shielding the printing function,on-line monitoring program and manually reset the relevant variables or modifying the user program for automatic reset.This paper can provide some reference for the troubleshooting and treatment of the control system which uses Siemens S7-300 to realize serial communication of peripheral equipment through CP340 module.
