ABB COM0011 2RAA005844A0007J系统模块
1.产 品 详 情 资 料：
Rx/Tx LED闪烁，但没有通信可能的原因1：MTMConnect和/或MTMReadCyc和/或TMDDefCyc被禁用。纠正措施1：启用MTMConnect、MTMReadCyc和MTMDefCyc功能块。可能的原因2：MTMConnect和/或MTMReadCyc和/或TMDDefCyc功能块显示不良状态。纠正措施2：检查不良状态的原因（请参阅联机帮助中MTMCommLib的状态代码），并对不良状态采取适当的纠正措施。可能原因3：MTMConnect功能块中Channel参数的值与硬件树中ABB COM0011 2RAA005844A0007J模块的位置不一致。纠正措施3：确保功能块中通道参数的值与硬件树中ABB COM0011 2RAA005844A0007J模块的位置一致。纠正措施4：如果即使在执行纠正措施1至3后情况仍然存在，则将ABB COM0011 2RAA005844A0007J模块热插拔到CEX总线上，并留出时间进行模块初始化。如果纠正措施是更换有故障的ABB COM0011 2RAA005844A0007J模块，请将其更换为具有相同版本硬件和固件的另一个ABB COM0011 2RAA005844A0007J模件。ABB COM0011 2RAA005844A0007J支持热插拔。
Rx/Tx LED's are flashing, but there is no communication Possible Cause 1: MTMConnect and/or MTMReadCyc and/or MTMDefCyc are disabled. Corrective Action 1: Enable MTMConnect, MTMReadCyc, and MTMDefCyc function blocks. Possible Cause 2: MTMConnect and/or MTMReadCyc and/or MTMDefCyc function blocks show a bad status. Corrective Action 2: Check the reason for the bad status (see the status codes for MTMCommLib in the Online Help), and take the appropriate corrective action for the bad status. Possible Cause 3: The value for the Channel parameter in the MTMConnect function block is not in accordance with the position of the ABB COM0011 2RAA005844A0007J module in the Hardware Tree. Corrective Action 3: Ensure that the value of the Channel parameter in the function block is in accordance with the position of the ABB COM0011 2RAA005844A0007J module in the Hardware Tree. Corrective Action 4: If the condition persists even after performing corrective actions 1 to 3, then hot remove and hot insert the ABB COM0011 2RAA005844A0007J module on the CEX-Bus and allow time for the module to initialize. If the corrective action is to replace the faulty ABB COM0011 2RAA005844A0007J module, replace it with another ABB COM0011 2RAA005844A0007J module which has the same version of hardware and firmware. ABB COM0011 2RAA005844A0007J supports hot swap.
