ABB 70AB01c-ES HESG447224R2通讯模块
1.产 品 详 情 资 料：
R（un）和F（ault）LED均熄灭可能原因1：ABB 70AB01c-ES HESG447224R2模块连接到控制器，并且配置没有下载到该位置的控制器。纠正措施1：确保在硬件树（控制生成器中）中为该位置配置了ABB 70AB01c-ES HESG447224R2模块，并将配置下载到控制器。可能原因2：ABB 70AB01c-ES HESG447224R2模块刚刚通电，或者正在配置和下载。纠正措施2：为模块初始化留出时间。纠正措施3：如果在执行纠正措施1和2后指示仍然存在，则建议采取以下纠正措施之一：•拆除ABB 70AB01c-ES HESG447224R2模块并将其插入CEX总线，并留出时间进行初始化。•如果CEX总线已经包含其他通信模块，并且这些模块上的所有LED都熄灭，或者如果此ABB 70AB01c-ES HESG447224R2是CEX总线上的模块，则检查PM86x处理器单元内的CEX总线保险丝。纠正措施4：如果在执行纠正措施1至3后指示仍然存在，则更换ABB 70AB01c-ES HESG447224R2模块。
Both R(un) and F(ault) LED's are OFF Possible Cause 1: The ABB 70AB01c-ES HESG447224R2 module is connected to the controller and the configuration is not downloaded to the controller for that position. Corrective Action 1: Ensure that the ABB 70AB01c-ES HESG447224R2 module is configured in the Hardware Tree (in the Control Builder) for that position, and that the configuration is downloaded to controller. Possible Cause 2: The ABB 70AB01c-ES HESG447224R2 module is just powered up or it is being configured and downloaded. Corrective Action 2: Allow time for the module to initialize. Corrective Action 3: If the indication persists after performing the corrective actions 1 and 2, then one of the following corrective actions is recommended: • Remove and insert the ABB 70AB01c-ES HESG447224R2 module to the CEX-Bus and allow time for it to initialize. • If the CEX-Bus already contains other communication modules and all the LED's on those modules are OFF, or if this ABB 70AB01c-ES HESG447224R2 is the only module on the CEX-Bus, then check the CEX-Bus fuse inside the PM86x Processor Unit. Corrective Action 4: If the indication still persists after performing the corrective actions 1 to 3, replace the ABB 70AB01c-ES HESG447224R2 module.
