In the following cases, the error completion signal in (d1)+1 is turned on and an error code is stored as the completion status

in the device (d2).

• The DBIMPORT(P) instruction is executed during execution of the database access instruction.

• The Unicode text file specified by (s) does not exist.

• The number of fields specified in the field name row of the Unicode text file does not match the number of fields in the

• A table definition start tag or end tag is missing in the Unicode text file.

• An out-of-range value is set for the key constraint in the Unicode text file.

• The database name, table name, or field name in the Unicode text file exceeds 32 characters.

• The number of tables or fields in the Unicode text file exceeds the maximum number.

• An out-of-spec data type is specified in the Unicode text file.

• The number of records in the Unicode text file exceeds the maximum number (for a programmable controller CPU with

firmware version earlier than "28").

• An access to the database has failed.

• The database name contains an invalid character.

• The total number of characters used in the database name specified in the Unicode text file and those used in the folder

path (including the drive path character) specified by (s) exceeds 128.

• The database that is already open exists and the DBIMPORT(P) instruction is executed.

• The number of characters on the comment line exceeds the maximum number.

• A character other than those that can be represented as ASCII codes (0020H to 007EH) is used in the folder name of the

Unicode text file specified by (s).

• The database name in the Unicode text file exists on the SD memory card and the database is used by another function

when the DBIMPORT(P) instruction is executed.

If an error is detected because of the Unicode text format, the DBIMPORT(P) instruction turns on the error termination signal

in (d1)+1 and stores the Unicode text line where an error was detected in SD760 and SD761.
