overwritten (1 ... 62 bytes)
Default value: 0x00 ≙ unspecified
Length of the EPC-ID/UID
single tag access (RF600)
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")
Data buffer with the EPC memory
data to be overwritten.
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]").
