The structure ST_RFID_TranspInfo indicates the type and the serial number of the last detected RFID transponder.

With the command 'GetInventory' this information will be requested and updated.

All manufacturers:

sSerialNumber

The serial number of the transponder (frequently 8 bytes) is indicated in the hexadecimal string sSerialNumber.

If Balluff RFID readers are used, the serial number of 13.56 MHz transponders is rotated byte-by-byte by the library function block. This takes place because the serial number read out from a transponder would otherwise not correspond to the serial number read out on another reader. This allows devices from different manufacturers to be operated together in the same network.

eType

The type of transponder is indicated as an enumeration value of the enumeration E_RFID_TranspType.

iHeadNumber

If a RFID reader with multiple read heads is connected, the head number where the RFID transponder was detected is output here.
