TAT (Reference)
The TAT (Turnaround Time) is the time from when the ID Slave's Command Execution Bit turns ON
until the ID Tag is communicated with and execution results are returned. The TAT can be calculated
with the following formula:
TAT = DeviceNet communications time + RFID communications time
RFID communications time
DeviceNet communications time : The communications processing time between the host device (e.g., DeviceNet Master)
: The communications processing time between the Antenna and the ID Tag.
For details, refer to Communications Time (Reference) in this section.
