Errors, Faults and Alarms

Errors, faults and alarms all represent problems of some kind. In the DSM an attempt is made to distinguish between the three classes of problems. This section will describe the difference between error, faults and alarms and explain how to treat them.

Commands should be provided for recovering from any of the above conditions. It should be possible to bring the device back into a usable state (as far as the hardware permits of course).
