6. HOW TO COMMUNICATE WITH ID TAGS
6.2.7 Fill data
The Fill Data command writes the same data to the ID tag in an amount equivalent to the
number of byte sets specified in the number of processed points specification area (Un
\
G4,
Un
\
G4004) from the address specified in the head address specification area (Un
\
G3,
Un
\
G4003).
The data for executing Fill Data are stored in the data storage area (Un
\
G100,
Un
\
G4100).
(1) Example of use
(a) When executing the Fill Data command in the data storage order 0000

(upper
-> lower) for the five bytes from address 0011

Point
(1) The Fill Data command ignores the write protect function in order to initialize all
data of the ID tag.
(2) When 0000
H
is specified in the number of processed points specification area
(Un
\
G4, Un
\
G4004), all data are specified.
