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.
