Module Error Definition
Table Module errors are expressed in two fields as four-digit Hex format
with the most significant digit as irrelevant (“don’t care”). The two
fields are “Module Error” and “Extended Error Information”. The
structure of the module error data is shown below.
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.

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.

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.
