Commands
■ WRITE (WT)
This command writes data to the ID Tag. If the ID Tag is not in the communications area, an error
response (end code: 72 = ID Tag non-existent) will be returned.
Processing Area Number: 1
Processing Area Number: 2
Data setting Sets the code format used to send responses for write data.
A: ASCII
H: Hexadecimal
When multiple processing areas are used, ASCII and hexadecimal can be specified at the same
time within a single command frame.
Processing area number
setting
Specifies the processing area number.
Setting range: 1 to 9, A (A = 10)
Write area start address Specifies the start address of the area in the ID Tag to be written to in 4-digit hexadecimal.
Setting range: 0000 to FFFF hex
When multiple processing areas are used, specify the areas in order starting from the smallest
address. The same area cannot be specified twice.
Number of write bytes When multiple processing areas are used, specifies the number of bytes to be written to the ID Tag
in 2-digit hexadecimal. The maximum number of bytes that can be written at one time is 256 bytes,
as follows:
• ASCII: 256 bytes (256 characters)
• Hexadecimal: 256 bytes (512 characters)
Setting range: 01 to FF hex
When multiple processing areas are used, set so that the total number of bytes to be written for all
areas is within 256 bytes, as follows:
Area (1) bytes +...+ Area (N) bytes ≤ 256 bytes
Write data Specifies the write data from the ID Tag.
The characters in ASCII indicate the number of write bytes and the characters in hexadecimal indi-
cate the number of write bytes x 2.
End code Indicates the execution result for the command.
The end code 00 indicates normal completion.
For details on end codes, refer to End code List.
