5.3 General notes on working with the UHF app version
• TID
Contains information on the manufacturer and transponder type, as well as a unique serial
number. This information serves the purpose of unique transponder identification.
• USER
A freely usable memory area that can be written with user-defined data.
This memory area is optional and is not present with all transponder types.
Example
Transponders with the chip NXP UCODE 7 have a USER memory area with 2048 bits (e.g.
RF645T, RF642L). Transponders with the chip NXP UCODE 8 have a USER memory area (e.g.
RF630L).
NOTICE
Memory areas > 2544 bits not addressable
Please note that memory areas > 2544 bits cannot be addressed with the SIMATIC RF160B
mobile reader.
Passwords
As a rule, each UHF-transponder has an Access and a Kill password.
• Access password
Access password with which individual memory areas are protected from read and write
access.
• Kill password
Password required to destroy the transponder.
Both passwords are 4 bytes long and are saved in the RESERVED memory area. The Kill
password is saved at the start of the RESERVED bank (first to fourth byte), followed by the
Access password (fifth to eighth byte).
You should change the passwords to ensure that no unauthorized persons have access to the
transponder data or can 'destroy' the transponder.
You can find detailed information on changing the passwords and locking memory areas
using the Access password in the section ""Tag Editor" menu (Page 57)".
