8.8.6 Command: Write and Verify
The Write and Verify command writes a number of bytes defined by the user. The written data
is also sent back to the interface and verified. Up to 128 bytes are transferred by default in a
write operation. Larger data volumes can be transferred in fragments. The written data is only
verified in the interface and is not sent back to the controller. If the verification fails, an error
message is output. If the command is processed without an error message, the data was veri-
fied successfully.
NOTE
With multitag applications enter the UID or EPC of the tag to be written.
NOTE
The command code for fast processing with the loop counter is 0x2008 (hex.) or
8200 (dec.).
See description of the output data, p. [}105].
Request
Loop counter See description of the output data
Command code 0x0008 (hex.), 8 (dec.)
Memory area See description of the output data
Read/write head address See description of the output data
Length UID/EPC Enter UID or EPC size in bytes, if a particular tag is to be writ-
ten. The UID or EPC must be defined in the write data (start
byte: 0). The function of the UID/EPC length is dependent on
the command used.
0: No entry of a UID/EPC for executing the command. Only
one tag can be located in the detection range of the read/
write device.
> 0: EPC length of the tag to be written if an EPC is present in
the write data
-1: NEXT mode: A tag is always only written if the UID/EPC is
different to the UID/EPC of the last read or written tag.
Start address Start address of the memory area on the tag to be written
(entry in bytes)
Length Length of the data to be written in bytes
Timeout See description of the output data
Write fragment No. 1: Use fragmentation
0: Do not use fragmentation
Read fragment No. 0
Write data,
Byte 0…(size of the UID/EPC - 1)
Optional: UID or EPC of the tag to be written
Write data,
Byte (size of the EPC)…127
