Module Error Field
The purpose of the module error field is to classify module errors into
three distinct groups, as described in the table below. The type of error
determines what kind of information exists in the extended error
information field. These types of module errors are typically reported in
the controller’s I/O status file. Refer to your controller manual for details.
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 analog modules.
Hardware Errors
General or module-specific hardware errors are indicated by module error
code 2. See Table 5.3 Extended Error Codes on page 5-6.
Configuration Errors
If you set the fields in the configuration file to invalid or unsupported
values, the module ignores the invalid configuration, generates a
non-critical error, and keeps operating with the previous configuration.
Table 5.3 Extended Error Codes on page 5-6 lists the possible
module-specific configuration error codes defined for the module.

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.
Configuration
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 range or input filter selection.
NOTE
If no errors are present in the module error field, the
extended error information field will be set to zero.
