A system and method for diagnosing one or more faults or one or more potential
faults in a machine. The system and method has a communications module for communicating
machine data between the machine and the system. It also has a fault recognition
module for analyzing the machine data, which can determine one or more faults or
potential faults in the machine. An expert system module having a fault tree is
guided through only a truncated portion of the fault tree based upon output from
the fault recognition module.
