5.6 Error Codes
The module error codes are listed in this section. Error codes returned from the
command list process are stored in the command list error memory region. A
word is allocated for each command in the memory area. The error codes are
formatted in the word as follows: The least-significant byte of the word contains
the extended status code and the most-significant byte contains the status code.
Use the error codes returned for each command in the list to determine the
success or failure of the command. If the command fails, use the error code to
determine the cause of failure.
Note: The Module Specific error codes (not DF1 compliant) are returned from within the module
and never returned from an attached DF1 slave device. These are error codes that are part of the
DF1 protocol or are extended codes unique to this module. The standard DF1 error codes can be
found in the DF1 Protocol and Command Set Reference Manual (Publication 1770-6.5.16) from
Rockwell Automation. The most common errors for the DF1 protocol are shown in the following
tables:
