View Faults, Alarms, Events, and Exceptions
When a condition occurs, the drive records the occurrence in the fault, alarm, event, or exception queue. These queues are accessible through software or the HIM and provide you with a history of each type of occurrence. You can also access diagnostic file parameters for additional information.

- Ports 01 through 09 use the format PEEE, indicating port number (P) and event number (EEE). For example, code 1 ‘Analog In Loss’ on an I/O module installed in Port 4 is displayed as: Fault Code 4001.
- Ports 10 through 14 use the format PPEEE, indicating port number (PP) and event number (EEE). For example, code 37 ‘S OverTemp Alm’ on Port 14 is displayed as: Fault Code 14037.
