Module Error Definition

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 in

Table 19

.

Module Error Field

The purpose of the module error field is to classify module errors into three
distinct groups, as described in

Table 20

. 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 modules.

Hardware Errors

General or module-specific hardware errors are indicated by module error code 1.
See the

General Common Hardware Error Codes table on page 116

for more

information.

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.

TIP

If no errors are present in the module error field, the extended error
information field will be set to zero.
