Error code
These codes are set in the Error Code field in the response area.
If an error response is returned (i.e., an error code other than 0000 hex), a record is stored in the com-
mand error log in the Reader/Writer. Records are not stored for errors for which responses are not
returned to the host device. Reader/Writer operating errors and system errors are recorded in the sys-
tem error log in the Reader/Writer.
Additional Information
