5.6.1 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.

5.6.2 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.
Note: If no errors are present in the module error field, the extended error
information field is set to zero.
Hardware Errors
General or module-specific hardware errors are indicated by module error code 001. See
Table 5-3 Extended Error Codes on page 5-5.

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.
