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:
