9.10 Operating mode "LOCK DATA”
In the “LOCK DATA” operating mode, a memory area is locked on an ID tag. A password is assigned
for the locked memory area. The password is necessary if the memory area is to be written to. The
field “Lock action” determines the state:
• Memory area locked: “Lock action = 0x01”
• Memory area not locked: “Lock action = 0x00”
Locking the memory area:
u The controller sets the command value “0x08”, the password (length 4 bytes) and the “Lock action”
in the process data output image. To identify the ID tag, the EPC and its length are also necessary.
w The “Memory Bank” field sets which memory bank is to be locked:
EPC:“0x01“
USER:“0x03“
u The controller starts the write operation with the status bit “Cmd Start”.
w The device acknowledges the start of the operation by setting the status bit “Cmd Start
Acknowledge” in the process data input image.
w The device sets the status bit “Cmd End” with the end of the operation.
u The locking is terminated.
If the operation was unsuccessful, the device sets the error value and the status bit "Cmd End"
in the process image. Data transfer is interrupted.
