Dear KMOS85, I am facing exact the same error message, 6ES7 138-7FA00-0AB0 , ADC/DAC Fault. The whole slot was not able to be used. I exchange the good one with the bad one, change slot 13 to slot 12 (they are the same type of modules, changing the Dip switch) , the slot 12 card originally was faulty became good , and the good one in slot 12 became bad. I am not sure what is happening right now, it was good. How you resolve your issue ? ------------------------------------------------------------------------------------------ |

We have resolved our IM152 ADC/DAC issue. There is a procedure to resolve the issue. 1. Initial condition: The IM152 and the modules are in powered. 2. Then, REMOVE all the field cables in the ADC/DAC faulty modules. 3. Then,power off the module by dismantle the modules. 4. Then, insert the modules again. The issue was resolved. 5. Then, measure the field cable to ensure no power supply from the field cables if 2DMU is configured. If the transducer/sensor has its own power supply, it may burn ADC input resistor or sensor. 6. Insert the field cables one channel by one channel to see the fault remained. |
