Creating a new signature for the error type is not difficult. One must read this signal and store the value with the other signal levels. Then tolerance level must be set for this signal if complex sensors (digital or analogue) are being used.

A mathematical model of the error signature is another way to compare the error signal to tolerance levels. It can be introduced as a confirmation; however mathematical models cannot be developed automatically. There are no known faultless automatic error learning modules yet available.

Once the error signal has been classified with its signature, tolerance levels and history, the system should ideally propose an error recovery routine. In some cases, depending on the type of error, it can be generated automatically. But this is a very difficult part of error recovery and usually it is done manually by the operator.
