Write_Epc_Id - Siemens SIMATIC RF600 Series Configuration Manual

9.5.2.5

Write_EPC_ID

The "Write_EPC_ID" block 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 block 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.
