Explanation for the instruction "Write"
Data type
DINT
INT
SINT
SINT[62]
SINT[10]
Default values Description
0x00 Physical address on the transponder
where the write starts. You will find
more information on addressing in the
section "Transponder addressing
(Page 96)".
With MV: Address is always 0.
0x00 Length of the data to be written
0x00 Length of the EPC-ID/UID
Default value: 0x00 ≙ unspecified
single tag access (RF200, RF300,
RF68xR)
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 with the data to be written.
With MV: The first byte encodes the
corresponding MV command.
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]").
