A major fault places the controller in fault mode. The controller stops and real-world outputs are put in their fault mode or program state mode, depending on the type of fault, as defined in the module's I/O configuration. A minor fault only sets a bit, and the controller continues to run.

The number of Instance Name selections depends upon the specific class name selected when programming the instruction.
