Module Error Types
Extended Error Information Field
Check the extended error information field when a non-zero value is present
in the module error field. Depending upon the value in the module error field,
the extended error information field can contain error codes that are
module-specific or common to all 1769 modules.
Hardware Errors
General or module specific hardware errors are indicated by module error
code 001 (binary).
Configuration Errors
In general, if you set the fields in the configuration file to invalid or
unsupported values, the module will generate an error. If this occurs while in
RUN mode, the module ignores the invalid configuration, generates an error,
and keeps operating with the previous configuration. If you set the field in the
configuration file to invalid or unsupported values before entering RUN mode,
the module will generate an error and the system will not enter RUN mode
until the problem is corrected. Configuration errors are indicated by module
error code 010 (binary).

Description
No Errors 000 No error is present. The extended error field holds
no additional information.
Hardware
Errors 001 General and specific hardware error codes are
specified in the extended error information field.
Configurat
ion Errors 010 Module-specific error codes are indicated in the
extended error field. These error codes correspond
to options that you can change directly. For
example, the input filter selection.
TIP
If no errors are present in the module error field, the extended
error information field will be set to zero.
