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 the
MicroLogix 1400 Programmable Controllers Instruction Set Reference Manual,
publication 1766-RM001
for more information.
.
Extended Error Information Field
Check the extended error information field when a non-zero value is present in
the module error field. See Extended Error Codes for 1762-IF2OF2 on page 188.
Hardware Errors
General or module-specific hardware errors are indicated by module error code 2.
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.
The table below lists the 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.
TIP
If no errors are present in the module error field, the extended error
information field is set to zero.
