Command Error Codes

As the list is read in from the processor and as the commands are processed, an
error value is maintained in the module for each command. The definition for
these command error codes is listed in Communication Error Codes on page
107. You can view the command error codes through the Ethernet diagnostics
port (see chapter 6, Diagnostics and Troubleshooting). They can also be
transferred from the module’s database to the processor.
To transfer the Command Error List to the processor, set the Command Error
Offset
parameter in the port configuration to a module database address that is in
the module’s Read Data area.

Note: The Command Error List must be placed in the Read Data area of the database, so it can be
transferred to the processor in the input image.
