The "Write" block writes the user data from the "IDENT_DATA" buffer to the transponder to
memory bank 3 (USER area). The physical address and the length of the data are
transferred using the "ADDR_TAG" and "LEN_DATA" parameters. Specific access to a
certain transponder is made with the "EPCID_UID" and "LEN_ID".

EPCID_UID SINT[62] 0 Buffer for up to 62 bytes EPC-ID
2 - 62-byte EPC-ID is entered at the
start of the buffer (length is set by
