This will clear not only the Error Log stored in volatile memory, but also the
error log events stored in the non-volatile memory.
Note Clearing the Error Log is not possible, if an error, which was just added to the
Error Log is still active. The cause of the active error has to be removed first
before the Error Log can be cleared. Attempting to clear the Error Log, while
an error is still active, does not result in an Error message from the CS1/
CJ1W-PRM21 Master DTM.
