Write

The "Write" writes the user data from the "IDENT_DATA" buffer to the transponder. The
physical address and the length of the data are transferred using the "ADDR_TAG" and
"LEN_DATA" parameters. For RF68xR readers, the instruction writes the data to memory
bank 3 (USER area). Specific access to a certain transponder takes place with the optional
"EPCID_UID" and "LEN_ID" parameters.

Default values Description
0 Buffer for up to 62 bytes EPC-ID, 8
bytes UID or 4 bytes handle ID.
2 - 62-byte EPC-ID is entered at
•
the start of the buffer (length is set
by "LEN_ID")
8-byte UID is entered at the start
•
of the buffer ("LEN_ID = 8")
4-byte handle ID must be entered
•
in the array element [5]-[8]
("LEN_ID = 8")
Default value: 0x00 ≙ unspecified
single tag access (RF620R, RF630R)
0 Data buffer in which the read data is
stored.
Note:
When necessary, an array of any size
can be transferred to this parameter.
Note that the array must be ≥ 10 bytes
long (e.g. "SINT[12400]").
