Hello Chris,

Let me know where once you have the serial numbers.

Deryck

The serial numbers that are giving us problems are: A03288A7 and A02ECC45.

Serial number A021B1D0 has been working well.

Both of those devices are coming back with the same revision from what I see. AB7312-B. Only differences i can see from the production data is the software difference which you have reverted.

Can you provide me again with a description of what the newer ones are doing? Are they locking up on the CAN or Profibus side?

Also, It look like you can check to be sure yourself. If you take off the front cover the PCB version should be printed just behind the LED’s.
