8.5.4 Command: Write
The Write command causes the read/write head to write data to tags in the detection range.
128 bytes are transferred in a write operation by default. Larger data volumes can be trans-
ferred in fragments. If a particular EPC is entered, the read/write head only writes the appropri-
ate tags. All other tags in the detection range are ignored in this case.
NOTE
„ With multi-tag applications enter the EPC of the tag to be written.
NOTE
The command code for fast processing with the loop counter is 0x2004 (hex.) or
8196 (dec.).

Length of EPC Enter the EPC size in bytes if a particular tag is to be written.
The EPC must be defined in the write data (start byte: 0). The
function of the length of the EPC depends on the command
used.
0: No entry of an EPC for executing the command. Only one
tag can be located in the detection range of the read/write
head.
> 0: EPC length of the tag to be written if an EPC is present in
the write data.
Start address Start address of the memory area on the tag to be written
(entry in bytes)
