Tag Memory Structure
Universally Unique Identifier (UUID)
Each tag has a different 64-bit hexadecimal UUID that is programmed during
the production process according to ISO/IEC15693-3 and cannot be changed
afterwards.
The numbering of the 64 bits is done according to ISO/IEC 15693-3 starting
with the least significant bit (LSB) 1 and ending with the most significant bit
(MSB) 64. This is in contrast to the general used bit numbering within a byte
(starting with LSB 0).
Byte 5 (bit 41…48) is the tag type. Byte 6 (bit 49…56) is the manufacturer code,
which coincides with the number of bytes/block.
The table below shows the RFID tags offered by Rockwell Automation and their
structure.
