The "Write_EPC_Mem" block overwrites the EPC memory of the RF600 transponder. The
length of the EPC memory to be overwritten is specified by the "LEN_DATA" parameter.

Parameter
Data type
Default values
Description
LEN_DATA
DINT
W#16#0
Length of the EPC memory to be
overwritten (1 ... 62 bytes)
LEN_ID
DINT
B#16#0
Length of the EPC-ID/UID
Default value: 0x00 ≙ unspecified
single tag access (RF680R, RF685R)
EPCID_UID
SINT[62]
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,
RF640R)
IDENT_DATA
SINT[10]
0
Data buffer with the EPC memory data
to be overwritten.
Note.
When necessary a byte/array of any
size can be transferred to this parame-
ter. Note that the array must be ≥ 10
bytes long (e.g. "SINT[12400]").
