ID Sensor Unit Functions
Operating Modes
The ID Sensor Unit has two operating modes: Run Mode and Test Mode
There are two ways to switch between the two operating modes.
1. The test switch on the Unit's front panel
2. A software switch in memory
Run Mode
In Run Mode, communications are performed when the Command Execution Bit (CIO n, bit 0) in the
Special I/O Unit Area is turned ON. All commands can be used in this mode. Communications results
and Unit status are shown on the status indicators and in the Unit Status (CIO n+7), Results
Information (CIO n+8), and Processing Results Monitor (CIO n+9) in the Special I/O Unit Area.
Test Mode
Test Mode is used to simulate actual operation. By using Test Mode, communications capability can be
measured easily in the actual operating environment. Test Mode is also useful for checking the
installation and checking the system while it is operating. The following five operations can be
performed in Test Mode.
When a V680-H01 Antenna is connected, tests other than the communications test cannot be performed. No matter
which test is set, only the RF Tag communications test operation will be performed.
• If the ID Sensor Unit is changed to Test Mode while a command is being executed, command execution will be
completed and then Test Mode will be entered.
• If an ID Sensor Unit error occurs, communications will stop regardless of the operating mode.

Operation Description
RF Tag communications test Executes communications with an RF Tag and outputs the results to
the Processing Results Monitor (CIO n+9) in the Special I/O Unit Area.
When using a Two-channels ID Sensor Unit, the test will be performed
alternately for Antennas 1 and 2.
Range level measurement Measures the Antenna and RF Tag installation distance in relation to
the RF Tag interrogation zone. The measurement results are output to
the Processing Results Monitor (CIO n+9) in the Special I/O Unit Area.
The results can also be checked on the Amplifiers operation indicators.
Write/read speed level measurement Measures the number of times that communications can be performed
consecutively based on the speed that RF Tags pass through the
Antenna interrogation zone. The measurement results are output to
the Processing Results Monitor (CIO n+9) in the Special I/O Unit Area.
The results can also be checked on the Amplifiers operation indicators.
Noise level measurement Measures the ambient noise level in the installation environment. The
measurement results are output to the Processing Results Monitor
(CIO n+9) in the Special I/O Unit Area.
Communications success rate
measurement Communicates 100 times with an RF Tag with no retries. The
measurement results are output to the Processing Results Monitor
(CIO n+9) in the Special I/O Unit Area.
