ID Sensor Unit Functions

Communications Test
A communications test is used to execute communications with an RF Tag and output the
communications results to the Processing Results Monitor (CIO n+9) in the Special I/O Unit Area.
When using a Two-channels ID Sensor Unit, RF Tag communications are executed alternately for
Antennas 1 and 2.
The communications test checks only the read operation and does not check the write operation.
The communications test will be performed with the contents that was set in advance in DM m+50 and DM m+51.
In the communications test, communications are executed alternatively for Antennas 1 and 2, regardless of the
specified Antenna number.
1.
Set the method to use to switch between Run Mode and Test Mode.
To start Test Mode using the switch on the front of the Unit, set DM m+80 to 0000.
To start Test Mode using bit 15 of CIO n+0, set DM m+80 to 0001.
After setting DM Area data with the Support Software, reset the power supply to the PLC or turn ON the Special I/O Unit
Restart Bit. The DM Area settings will be transferred to the ID Sensor Unit when the power supply turns ON or when the
Special I/O Unit Restart Bit is turned ON.
2.
Set the operation to perform in Test Mode.
Set DM m+50 to 0000 and set the number of test bytes in DM m+51.
DM Area addresses are given in reference to “m,” where m = 100
×
Unit number.
3.
Turn ON the test switch.
The operation in Test Mode is started using the method set in the DM Area.
To start Test Mode using the switch on the front of the Unit, set DM m+80 to 0000.
To start Test Mode using bit 15 of (CIO n+0), set DM m+80 to 0001.
4.
Communications with the RF Tag will begin.
Communications will be performed with the RF Tag and the communications results will be output to the Processing Results
Monitor (CIO n+9) in the Special I/O Unit Area.
