Setting Write Protection for V680 Models
The same method is used as that for setting ID Tags when using V680 commands. Refer to step 2 (Set
the write protection function of the ID Tag) of Setting Write Protection when Using V680 Commands.
Disabling Write Protection When Using V600 Commands
Disabling ID Tag write protection for part of the area being used:
To temporarily disable write protection when you want to, for example, rewrite data that is being write-
protected, set the most significant bit of the following address for the ID Tag memory to “0.”
- V600 EEPROM write protection Address 0000H
- V600 S-RAM write protection Address 0002H
- V600 write protection Address 0000H
Disabling Write Protection for all OMRON-made RFID Systems:
To disable write protection in order to, for example, use the entire memory area of the ID Tag as user
memory, use either of the following methods to set all of the ID Controllers.
• Using the DIP Switch (when pin 1 on SW3 is set to OFF):
Pin 7 on SW4: Set the write protection setting to “ON” to disable write protection.
• Using the internal setting (when pin 1 on SW3 is set to ON):
PARAMETER SET (SP) COMMAND processing code “H”: Set the write protection setting to “00” to
disable write protection.
Precautions on Using Write Protection
The write protection function is supported only for these OMRON ID Controllers. It is not valid for reader/writers manufactured by
other companies.
For details on the PARAMETER SET (SP) COMMAND, refer to Command and Response Formats.
