9.7 Operating mode "WRITE EPC”
In the operating mode “WRITE EPC”, a new EPC is written to an ID tag. The current EPC and the new
EPC must be known. The data is sequentially transferred from the device to the controller.
Transfer data from the device to the controller:
u The controller sets the command value “0x05”, the length and the value of the current EPC in the
process data output image.
u The controller sets the length and value of the new EPC in the process data output image.
u The controller starts the write operation with the status bit “Cmd Start”.
w The device acknowledges the start of the write operation by setting the status bit “Cmd Start
Acknowledge” in the process data input image.
