ERR_SUB
A: The PLC turns ON INHIBIT and sends the execution command to the FL Remote ID.
B: The FL Remote ID checks that INHIBIT
is ON, determines the CMD (command), LEN (data length),
and ADDR (start address), and then turns ON BUSY.
C: The FL Remote ID starts communications with an RF Tag when one enters the Antenna's
communications range.
D: The FL Remote ID turns ON NORMAL when communications with RF Tag end normally. For READ
DATA, the read data is output to the FL Remote ID. For NOISE MEASUREMENT, the measurement
data is output to the FL Remote ID.
E: The RF Tag moves outside the Antenna's communications range within 100 ms after the FL Remote
result is output.
F: The result output is turned OFF 100 ms after the FL Remote ID result is output.
When measuring noise, the noise will be measured and the results will be output alternately while
INHIBIT is OFF, regardless of whether there is an RF Tag present.
G: The FL Remote ID starts communications with RF Tag when it enters the Antenna's communications
range.
H: The FL Remote ID turns ON NORMAL when communications with the RF Tag ends normally. For
READ DATA, the read data is output to the FL Remote ID.
I: Result output is turned OFF when the RF Tag moves outside the Antenna's communications range
100 ms after the FL Remote ID result is output.
J: The PLC turns OFF INHIBIT
to prevent command execution by the FL Remote ID.
K: The FL Remote ID confirms that INHIBIT
is OFF, and then turns OFF BUSY.
