User's Manual Pub. 0300241-02 Rev. A
Analog module errors are expressed in two fields as four-digit Hex format with
the most significant digit as "don't care" and irrelevant. The two fields are
"Module Error" and "Extended Error Information". The structure of the module
error data is shown below.

4.6.1 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.

4.6.2 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.

Description
No error is present. The extended error
field holds no additional information.
General and specific hardware error
codes are specified in the extended error
information field.
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.
