ABB YPG110E YT204001-FD1模块卡件
1.产 品 详 情 资 料：
RxB LED熄灭。线路B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。两个模块上的DUAL LED熄灭（仅限CI854A）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。检查该模块的冗余是否已在CBM中设置，并已下载配置。R（un）和F（ault）指示灯均不亮。CI855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总线上没有其他单元指示灯点亮：检查是否将包括CI855在内的有效硬件配置下载到控制器。检查处理器单元内的CEX总线保险丝从处理器单元启动复位信号（INIT）更换CI855单元F（ault）LED亮起检查所有电缆和连接器是否损坏、松动或连接不良。必要时进行维修R（un）LED闪烁检查相关单元是否正在发送数据。检查CI855板是否正在重新启动或配置过程中。如果是这样的话，请留出时间来完成。如果情况仍然存在：请停止应用程序并启动重新启动。更换CI855板。
RxB LED is OFF No communication on Line B. • 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. DUAL LED is OFF on both modules (CI854A only) The CI854A board is in the process of being restarted or configured. Allow time for this to finalize. Check that the redundancy for this module is set within CBM and the configuration is downloaded.Neither R(un) nor F(ault) LEDs are ON The CI855 board is in the process of being restarted or configured. Allow time for this to finalize. If the condition persists, and no other unit LED on the CEX-Bus is lit: Check that a valid HW configuration including the CI855 is downloaded to the controller. Check the CEX-Bus fuse inside the processor unit Initiate a reset signal (INIT) from the processor unit Replace the CI855 unit F(ault) LED is ON Check all cables and connectors for damage and loose or poor connections. Repair as necessary R(un) LED is flashing Check that the relevant units are sending data. Check if the CI855 board is in the process of being restarted or configured. If so, allow time for this to finalize. If the condition persists: Halt the application program and initiate a restart. Replace the CI855 board.
