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。

Abstract： 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.

玻璃珠供料裝置（下文简称供料装置）是陶瓷电熔炉玻璃固化技术路线的核心设备之一，通过有序控制整套装置中的称重单元、气动阀门、锁室等相关设备，可实现对玻璃珠的称重及下料量的精准控制，配合一定比例的废液加入到熔炉，得到合格的熔融玻璃体。供料装置自动运行时在下料完成后即进行下个批次的备料工作。在完成称重备料后，控制系统将玻璃珠已下料总量、当前称重量、当前批次、当前时间和日期等重要数据发送到热敏打印机进行就地打印。

根据值班人员反馈，在熔炉正常运行时，巡检发现供料装置就地热敏打印机缺纸报错，但供料装置仍能正常工作。……
