8.8.31 Command: Set perma lock
NOTE
The command code for rapid processing with the loop counter is 0x2105 (hex.) or
8453 (dec.).
The Set perma lock command permanently sets a complete memory block of the tag with a
direct command and permanently locks it. When sending the command, only one tag can be
located in the detection range of the read/write device.
The function is only available in HF applications in single-tag mode. A fault signal is output with
multitag applications. To troubleshoot, set the HF: multitag parameter to 0: multitag mode off.
See description of the output data, p. [}105].

Command code 0x0105 (hex.), 261 (dec.)
Read/write head address See description of the output data
Length UID/EPC 0: The command is executed for the tag which is located in
the detection range of the read/write device.
> 0: EPC or UID length of the tag to be locked if an EPC or
UID is present in the write data
-1: NEXT mode: A tag is only ever protected if the UID/EPC
differs from the UID/EPC of the tag last read or written to.
Start address UHF: not required
HF: Address of the first bit in the block to be locked (EEPROM
tag: 0, 4, 8, …, FRAM tag: 0, 8, 16, …)
Memory area Possible values:
n HF: USER memory (memory areas 1… 4)
n UHF: Kill password (memory area 1), PC and EPC (memory
area 1), USER memory (memory area 3) Access password
(memory area 4)
UHF: The entire memory area selected is locked irrevocably
from write access. Kill password and access password are
also locked irrevocably from read access.
HF: Entry of the memory area not necessary
Length HF: Length of the data to be locked in bytes. Only multiples
of the block size can be specified.
0: 1 Lock block
UHF: not required
