A control unit has a microprocessor, a non-volatile program memory, a volatile or erasable non-volatile monitoring result memory and a non-volatile, writable backup memory. The program memory stores both a control program routine and a monitoring program routine for monitoring the controlled system. An obtained monitoring result is stored in the monitoring result memory and is transferred to the backup memory.
