• The words allocated to the ID Sensor Unit in the Special I/O Unit Area are determined by the setting of the unit number
switches on the Unit's front panel. Set unit numbers so that the same words are not allocated to more than one Unit. (Refer to
p. 63 for the setting method.)
• If the same unit number is set for more than one Special I/O Unit, a fatal error (No. duplication error on CX-Programmer or Unit
Number Duplication on Programming Console), and the PLC will not operate.

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
SECTION 5
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.
Operating Modes
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.
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.

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.

There are seven execution sequences that can be used to communicate with the RF Tag. The sequence is
specified in the Communications Specification (CIO n+1, bits 04 to 07) in the command settings in the Special
I/O Unit Area.
Name
Trigger
0
When the Command Execution Bit turns ON, communications are performed with the
RF Tag in the interrogation zone and processing is ended.
1
After the Command Execution Bit turns ON, the ID Sensor Unit waits until an RF Tag
is detected in the interrogation zone, communications are performed, and processing
is ended.
2
The operation for a single auto specification is repeated. Once communications have
been completed with a specific RF Tag, communications will not be performed with it
again even if it remains in the interrogation zone. Processing is ended when the
Abort Bit is turned ON.
3
When the ID Sensor Unit receives a command, it communicates with an RF Tag and
returns a response. After communicating, all further operations with that RF Tag are
prohibited. The ID Sensor Unit communicates with only one RF Tag in the
interrogation zone. If an RF Tag that has been communicated with for a trigger
specification is within the interrogation zone, the ID Sensor Unit will not communicate
with it a second time.
4
When the ID Sensor Unit receives a command, it waits until an RF Tag is detected
within the interrogation zone, then returns a response. After communicating, all
further operations with that RF Tag are prohibited. After returning the response, the
ID Sensor Unit again waits for an RF Tag to approach it, and continues repeating the
operation until the Abort Bit turns ON.
5
When the ID Sensor Unit receives a command, it communicates with all RF Tags in
the interrogation zone, returns responses in order. After communicating, all further
operations with those RF Tags are prohibited. If there are no RF Tags in the
interrogation zone, the ID Sensor Unit will return an RF Tag missing error.
6
When the ID Sensor Unit receives a command, it waits for RF Tags to approach it. It
communicates with each RF Tag in the interrogation zone, and returns responses in
order. After communicating, all further operations with those RF Tags are prohibited.
After returning the responses, the ID Sensor Unit again waits for RF Tags to
approach it, and continues repeating the operation until the Abort Bit turns ON.

Write Protection
The write protection function is provided so that product model numbers and other important product
information stored in the RF Tags can be protected from being lost though careless write operations. We
recommend that write protection be set after important data has been written.
Either of two write protection methods can be used, the V680 method or the V600 method. The method can be changed by
setting DM m+2 (Write Protection Disable Setting). Normally use the V680 method. If a V600 system is replaced with the V680,
the V600 method can be used to enable using the current RF Tag memory map, eliminating the need to change system
programming.
Setting Write Protection Using the V680 Method
Write protection is set in four bytes of RF Tag addresses 0000 to 0003 (hex). The setting for the most
significant bit of address 0000 (hex) specifies whether or not write protection is enabled for the RF Tag.

setting area (addresses 0000 to 0003 hex) and following addresses at the same time, a write protection error will occur.
If write protection is disabled, you can use the write protection setting area (addresses 0000 to 0003 hex) as normal user
memory. If you use the write protection setting area (addresses 0000 to 0003 hex) as normal user memory, be sure to disable
write protection in the ID Sensor Unit.

Setting Write Protection Using the V600 Method
With the V600 Series, different write protection setting methods are used for EEPROM Data Carriers
(V600-D23P@@) (without batteries) and SRAM Data Carriers (with batteries). When using V600
commands with the V680-series ID Sensor Unit, the data memory setting in the ID Sensor Unit and the
type of RF Tags can be selected to enable using the previous write protection setting method.
• Using EEPROM RF Tags (V680-D1KP@@)
V600 EEPROM Write Protection Method
• Using FRAM RF Tags (V680-D2K/8K/32KF@@)
V600 SRAM Write Protection Method
The ID Sensor Unit will automatically switch between the V600 EEPROM write protection method and the V600 SRAM
write protection method. No user setting is required.
SECTION 5
 V600 EEPROM Write Protection Method
(The following information applies when the V600 write protection
method is set and V680-D1KP@@ RF Tags are used.)
Write protection is set by writing the end address to be protected in address 0000 hex of the RF Tag.
The area between address 0001 hex and the end address will be write-protected. The status of the
most significant bit of address 0000 hex determines whether write protection is enabled.

ID Sensor Unit Functions
RF Tag Service Life Check
The Number of Writes Control command can be used to determine whether the RF Tag write limit has been
exceeded. Detecting when the write life has been exceeded for an RF Tag is performed by using the Number
of Writes Control command that determines whether the write count (100,000 times or a user specified value)
for an RF Tag has been exceeded.
There are two ways to manage the number of writes. One is to add to the number of writes and then detect
when the total exceeds 100,000 writes. The other is to subtract from a user-specified number of writes and
then detect whether the write count has been exceeded.
 Number of Writes Control 1 (Life Control = Preset Number of Writes)
The Number of Writes Control Area consists of 3 bytes from the
start address. The Number of Writes Control command is
executed with an Add specification. The specified numbers of
writes are added and the total is written to the control area.
SECTION 5

writes, the value will not be changed.
• Application Method
The life of the RF Tag can be managed by updating the number of writes value when data is written to
the address most frequently written. (The life of EEPROM RF Tags is 100,000 writes for any one data
block (8 bytes), so the number of writes must be counted for the address that is written most
frequently.) It is also possible to confirm the number of writes without updating the number of writes
value.

 Number of Writes Control 2 (Life Control = User Setting)
The Number of Writes Control Area consists of 3 bytes from the
start address. The Number of Writes Control command is
executed with a Subtract specification. The specified number of
writes is subtracted and the result is written to the control area.
Therefore, to enable control of the number of writes, the
maximum number of writes must be written to the Number of
Area start

Writes Control Area beforehand. The user-specified number of
writes can be set to up to 16,700,000. The specified number of
writes for EEPROM RF Tags, however, is 100,000 writes
(0186A0 hex) at 25C max., so be sure to set the number of
writes to 100,000 or less. When the value in the number of writes control area is less than 0, the Status
Flag (CIO n+8, bit 04) in the Results Information turns ON. If the value in the control area is already
less than 0, the value will not be changed.
• Application Method
SECTION 5
RF Tag Service Life Check
110
A user-specified number of writes can be used for life control by writing the desired value in the
Number of Writes Control Area in advance. The life of the RF Tag can be managed by updating the
number of writes value when data is written to the address most frequently written. (The RF Tag has a
limited life for any one block of 8 bytes, so the number of writes must be counted for the address that is
written most frequently.) It is also possible to confirm the number of writes without updating number of
writes value.

RF Tag Memory Check
The Memory Check command performs an RF Tag memory check. A CRC (Cyclic Redundancy Check) code
calculation, write, and comparison are made using the check block unit specified by the user. The CRC code
is calculated from the generated polynomial expression X16 + X12 + X5 + 1.
A memory check is performed by using the Data Check command
Address (hex)
with a Calculation processing specification to write the check code
00
and a Verification processing specification to verify the check code.
01
The start address and the number of bytes determine the specified
check block. All but the last 2 bytes are the area to calculate and the
last 2 bytes are the check code area.
When the Data Check command is executed to write the check code,
the CRC code is calculated for the area to calculate and written in the

When the Data Check command is executed to verify the check code, the CRC code is calculated for the area

in the check code area, the Normal End Flag (CIO n+7, bit 01) in Unit Status will turn ON. If they are not the
same, the Error End Flag (CIO n+7, bit 02) in Unit Status will turn ON, and the Status Flag (CIO n+8, bit 04) in
the Results Information will turn ON as a warning.
• Application Method
After writing the data, the Data Check command is executed with a Calculation processing specification to
calculate and write the check code. Before reading the data, the Data Check command is executed with a
Verification processing specification to verify the check code. This enables detecting internal data corruption
that might occur in the RF Tag when the data is not being accessed.

The following ladder programming uses the Read command and the IORD instruction to read 512
bytes of data. The IORD instruction is executed twice to read 256 bytes (128 words) each time.
When the execution input turns ON, settings are made in the Special I/O Unit Area using MOV

When the execution input turns ON, settings are made in the Special I/O Unit Area using the MOV and
MOVL instructions and the command is executed. When communications with the RF Tag have been
completed, the Normal End Flag (CIO n+7, bit 01) or Error End Flag (CIO n+7, bit 02) is turned ON.
Read data can be used after the Normal End Flag (CIO n+7, bit 01) has been ON.
To end command execution while waiting for the RF Tag, turn ON the Abort Input.

When the command execution input turns ON, settings are made in the Special I/O Unit Area using
MOV instructions and the command is executed. When communications with the RF Tag have been
completed, the Normal End Flag (CIO n+7, bit 01) or Error End Flag (CIO n+7, bit 02) is turned ON.
The following ladder programming uses the Write command and the IOWR instruction to write 512
bytes of data.
The IOWR instruction is executed twice to write 256 bytes (128 words) each time.
