The addressed memory area for the read/write operation cannot be outside the memory area of
the device:
u auto-read/write address + data length for auto-read and auto-write ≤
number of available bytes on the device
The minimum length for auto-read and auto-write is 2 byte and the maximum length is 28 bytes.
9.12.4 Parameter "ID Tag Memory Area for Auto-Read/Write"
In the operating mode “READ DATA AUTO” (Ò Operating Mode “READ DATA AUTO"/20) / “WRITE
DATA AUTO” (Ò Operating Mode “WRITE DATA AUTO"/21), the device reads / writes a specified
number of data bytes. The parameter determines the memory area on the ID tag that is read from and
written to.
The following memory areas can be used with the parameter:
“0x00”: none (switch off READ DATA AUTO / WRITE DATA AUTO)
”0x01”: Memory area EPC
”0x02”: Memory area TID
”0x03”: Memory area USER
For the operating mode “WRITE DATA AUTO”, only the memory area USER is valid.
9.12.5 Parameter “ID Tag Access Password"
The ID tags can be write-protected. A password is then required for access. The parameter stores the
password in the device. The password is used for all write accesses to the ID tags.
The password is 4 bytes long. If all 4 bytes have the value “0x00”, no password is used to access the
ID tags.
The password is used for all ID tags. Individual passwords per ID tag are not possible.
w The device cannot access the ID tags when
u a password has been stored in the device with the parameter “ID tag access password” and
u the ID tags are not protected with a password.
9.12.6 Parameter "ID Tag Selection Target
With ID tag selection, only desired ID tags are detected by the device. All ID tags that do not meet the
criteria are rejected by the device and not taken into account.
An ID tag is selected by comparing data stored on the ID tag and a given bit mask. The data is stored
in one of the following memory areas for the purpose of comparison: EPC, TID or USER.
The parameter defines the memory area for the comparison. The following memory areas can be set:
• EPC
• TID
• USER
• No selection target
The ID tag selection is inactive if "No selection target" is set.
9.12.7 Parameter "ID Tag Selection Mask”
With ID tag selection, only desired ID tags are detected by the device. All ID tags that do not meet the
criteria are rejected by the device and not taken into account.
