Hi gerdam.

Welcome to the forum, what is your communication method? Could it be that the path you are trying to use has been reset to default addresses and settings due to the low battery fault?

Try connecting directly using the Modbus or Modbus Plus port....

Once the processor has lost its' memory, the comm addresses default back to 1 for MB & MB+. Once the program is reloaded and the processor is started to Run, the addresses will be set by the newly reloaded program.
