SECTION 6
Controlling the ID Sensor Unit
Noise Measurement Command
1) Use the user program to set the storage words for noise measurement data and other parameters in
the Special I/O Unit Area.
2) Use the user program to turn ON the Command Execution Bit (CIO n, bit 00) in the Special I/O Unit
Area.
3) When the ID Sensor Unit detects that the Command Execution Bit has turned ON, it turns ON the ID
Busy Flag (CIO n+7, bit 00).
4) The ID Sensor Unit measures the noise around the Antenna, places the Results Information (CIO
n+8) and Processing Results Monitor information (word n+9) in the Special I/O Unit Area, places the
noise measurement results in the data storage words, turns OFF the ID Busy Flag (CIO n+7, bit 00),
and turns ON the Normal End Flag (CIO n+7, bit 01) for one scan.
5) Use the Results Information (CIO n+8), the Processing Results Monitor information (CIO n+9), and
noise measurement results in the data storage words in the user program only after the Normal End
Flag (CIO n+7, bit 01) turns ON.
