 ID Tag within the Antenna's Communications Range
 ID Tag Not within Communications Range
A: The PLC turns ON TRG, and sends the execution command to DeviceNet Remote ID Controller.
B: The DeviceNet Remote ID Controller receives TRG, determines the CMD (command), LEN (data
length), and ADDR (start address), then turns ON HS output, starts communications with the ID Tag,
and turns ON BUSY.
C: HS output will turn OFF when TRG turns OFF.
D: The DeviceNet Remote ID Controller turns ON NORM when communications with ID Tag ends
normally.
E: The PLC checks that the NORM signal is ON, and then the data output is read.
F: Once the time set in the output mode has elapsed, the DeviceNet Remote ID Controller turns OFF
the data output and NORM.
G: The PLC turns ON TRG and sends execution command to DeviceNet Remote ID Controller.
H: The DeviceNet Remote ID Controller receives TRG, turns ON HS output, and then starts
communications with the ID Tag ID and turns ON BUSY.
I: HS output will turn OFF when TRG turns OFF.
J: When communications with ID Tag ends in an error, DeviceNet Remote ID Controller turns ON ERR
(ID Tag communications error) and ERR_SUB0 (No ID Tag).
K: The PLC confirms that the ERR signal is ON, and then the data output is read.
L: Once the time set in the output mode has elapsed, the DeviceNet Remote ID Controller turns OFF
ERR and ERR_SUB0.
