Write_EPC_ID

The "Write_EPC_ID" instruction overwrites the EPC-ID of the RF600 transponder and
adapts the length of the EPC-ID in the memory of the transponder. The new EPC-ID
length to be written is specified with the "LEN_ID_NEW" parameter and the previous
EPC-ID is specified using the "LEN_ID" and "EPCID_UID" parameters.
Make sure that when you execute the instruction only one transponder is located in the
antenna field. This ensures that the identification when writing the ID is unique. If there
is more than one transponder in the antenna field, a negative response is returned.
