ABB YPH105E YT204001-FC1通讯模块
1.产 品 详 情 资 料：
R（un）和F（ault）指示灯均不亮。CI854/CI854A板正在重新启动或配置过程中。请留出时间以便最终确定。如果情况持续存在，并且CEX总线上的所有其他单元都有未点亮的LED：•检查是否将包括CI854在内的有效硬件配置下载到控制器。•检查PM8xx处理器单元内的CEX总线保险丝。•从PM8xx处理器单元启动复位信号（INIT）。•更换CI854/CI854A装置。F（ault）LED亮起检查CI854板是否正在重新启动。请留出时间以便最终确定。检查CBM中的CI854/CI854A是否没有报告配置故障。如果状态保持不变，则启动来自PM8xx处理器单元的复位信号（INIT）。如果复位后状态仍然保持，则更换CI854/CI854A装置。RxA LED熄灭。线路A上无通信。•检查从属设备是否已配置并连接到此线路。•如果使用了冗余从属设备，请检查冗余是否正常工作。备份从属设备必须响应主设备发送的生命列表请求。•检查所有电缆和接头是否损坏、松动或接触不良。
Neither R(un) nor F(ault) LED’s are ON The CI854/CI854A board is in the process of being restarted or configured. Allow time for this to finalize. If the condition persists, and all other units on the CEX-bus have non-illuminated LEDs: • Check that a valid HW configuration including the CI854 is downloaded to the controller. • Check the CEX-bus fuse inside the PM8xx processor unit. • Initiate a reset signal (INIT) from the PM8xx processor unit. • Replace the CI854/CI854A unit. F(ault) LED is ON Check that the CI854 board is in the process of being restarted. Allow time for this to finalize. Check that there is no configuration fault reported from CI854/CI854A in CBM. If the status remains initiate a reset signal (INIT) from the PM8xx processor unit. If the status still remains after the reset replace the CI854/CI854A unit. RxA LED is OFF No communication on Line A. • Check that slaves are configured and connected to this line. • If redundant slaves are used check that the redundancy is working properly. The backup slave has to answer to the life list requests sent by the master. • Check all cables and connectors for damage and loose or poor connections.
