IC693CMM302M 技术参数使用说明
2.1环境因素对纵切计量控制系统的影响 由于纵切线称重区域环境恶劣，粉尘、杂物、油污、捆带等严重影响着计量控制系统现场检测元件的正常工作，如磁尺、接近开关、电子秤、压力传感器等极易损坏。特别是接近开关安装在步进梁上，由于现场机械设备晃动，接近开关被严重撞坏。 2.2计量控制系统设计的缺陷 2.2.1 DC24V电源 计量控制系统称重区域控制箱的直流24V电源既是模板电源又是现场检测元件供电电源，同时现场使用的电源回路没有安装保险，当现场电源线路出现“接地”或“短路”时，致使控制箱的直流24V电源跳，维护人员分析处理故障难度大. 2.2.2 计量信息传送功能 计量信息传送主要由计量控制系统的称重操作台进行重量传送，称重操作台通过Profibus-DP网络将成品卷信息传递给纵切基础自动化PLC系统，PLC系统在通过Ethereale网络传送给 HMI系统，HMI系统再传送给L3系统。由于Profibus-DP网络接口的备品备件已经升级不再生产，现场元件运行不稳定，Profibus-DP网络系统容易出现故障，重量信息不能正常传送，作业线通讯中断，液压、润滑系统出现跳泵的现象。 2.2.3计量信息确认功能
