Viewing Controller Fault Details
Note: The fault action displayed in the expanded fault details indicates the fault action specified by
the fault that was logged, but not necessarily the executed fault action. To determine what
action was executed for a particular fault in a configurable fault group, you must refer to the
hardware configuration settings.
To see controller fault details, click the fault entry. The detailed information box for the fault appears.
(To close this box, click the fault.)
The detailed information for controller faults includes the following:
Error Code
Further identifies the fault. Each fault group has its own set of error codes.
Group
Group is the highest classification of a fault and identifies the general
category of the fault. The fault description text displayed by your
programming software is based on the fault group and the error codes.
Action
Fatal, Diagnostic, or Informational. For definitions of these actions, refer to
Fault Actions and Fault Action Configuration.
Task Number
Not used for most faults. When used, provides additional information for
Technical Support representatives.
Fault Extra Data
Provides additional information for diagnostics by Technical Support
engineers. Explanations of this information are provided as appropriate for
specific faults in Controller Fault Descriptions and Corrective Actions below.
User-Defined Faults
User-defined faults can be logged in the Controller Fault Table. When a user-defined fault occurs, it is
displayed in the appropriate fault table as Application Msg (error_code): and may be followed by a
descriptive message up to 24 characters. The user can define all characters in the descriptive
message. Although the message must end with the null character, e.g., zero (0), the null character
does not count as one of the 24 characters. If the message contains more than 24 characters, only
the first 24 characters are displayed.
Certain user-defined faults can be used to set a system status reference (%SA0081–%SA0112).
User-defined faults are created using SVC_REQ 21: User-Defined Fault Logging, which is described in
Chapter 6.
Note: When a user-defined fault is displayed in the Controller Fault table, a value of -32768 (8000
hex) is added to the error code. For example, the error code 5 will be displayed as -32763.
