Each fault is classified as one of the following:

Non-User — A fault caused by various conditions that cease logic
program execution. The user-fault routine is not run when this fault
occurs.

Non-Recoverable — A fault caused by the user that cannot be recovered
from. The user-fault routine is run when this fault occurs. However, the
fault cannot be cleared.

Recoverable — A fault caused by the user that can be recovered from in
the user-fault routine by resetting major error halted bit (S1/13). The
user-fault routine is run when this fault occurs.

Refer to chapter 20 for more information regarding MicroLogix 1000 HHP
