End Codes An end code of 14 (format error) will be returned if the length of the command is
incorrect or the first word of write data isn’t in the first frame.
An end code of 15 (entry number data error) will be returned if the digits of write
data aren’t 0 or 1, the specified write data exceeds the data area boundary, the
beginning word isn’t specified in BCD, or the write data isn’t hexadecimal. (An
end code of A5 will be returned instead of 15 for non-hexadecimal write data in
multiple command frames.)

Limitations Except for the first word of the write data, the write data can be divided into multi-
ple frames.
DM 6656 to DM 6999 do not exist, but an error won’t occur if the command at-
tempts to write to these words. Likewise, an error won’t occur if the command
attempts to write to extension DM words (DM 7000 to DM 9999) which haven’t
been allocated in the UM area.
