■Highly Functional RFID System

In addition to 1-to-1 communication between a Tag and an antenna, the RFID System operates in either multiple simultaneous access mode, selective access mode, or FIFO (first-in, first-out) read/write mode. In multiple simultaneous access mode, if there is more than one Tag in the communications area, the RFID System reads and writes data from and to all the Tags at one time. In selective access mode, th e user can specify the Tags from and to which data is read and written. In FIFO read/write mode, the RFID System reads and writes data to one Tag after another as they come into the communications area.

■Support of off-line EAS Mode

The Reader/Writer can operate in EAS mode (see 3-7 in S ection 3) as a standalone device, with no need to connect with the host.

■I/O function

By issuing commands from the host, the user can operate three input points and four output points.

■Protection Construction

The protection construction IP60 has been achieved in the Reader/Writer.

Note:

In the configuration, where multiple Reader/Writers are connected via an RS-485 interface, the commands in a Communication Mode by which responses are returned at the Tag’s entry into the communication area, such as those in the Auto or Repeat Modes, cannot be executed simultaneously. The responses from the Reader/Writer will collide, preventing the host from receiving them normally. Such commands must be executed from the Polling Command, or by the time-shared processing performed by the host.

The Reader/Writer operates in either Online Mode, in which commands are given by the host, or in Offline Mode, in which the EAS function (refer to SECTION 3-7) performs the configuration, when the host is disconnected and the communication test between the antenna, the Reader/Writer and the Tags.

The factory default is set to Offline mode. To change the mode to the Online Mode, connect the host and execute the Stop Command (ST). To always start the Reader/Writer in the Online Mode, the default mode is disabled using the Offline Mode Setting Command (FL).

When the Reader/Writer is turned on in Online Mode, it remains in a stand-by state, until commands from the host are received.

In the Offline Mode, the Reader/Writer starts detecting the EAS-enabled Tags (the EAS function mounted on the Tags is not disabled) from the moment it is turned on in this mode the COMM LED remains flashing. At the entrance of an EAS-enabled Tag into the antenna communication area, the external output turns ON for the specified time. The OUT1 LED light indicates normal communication between the Reader/Writer and the Tags .

To check the communication status in the Offline Mode, the EAS on the Tags must be enabled in advance.

Note:

●If the type of Tags used and the chip op erating mode setting do not match, the Reader/Writer will not respond to the Tags. The No Tag Error （code: 72） results.

●Specifying the commands or functions unavai lable in th e specif ied Chip Op eration M ode will r esult in a Format Error (code: 14).

●The communication test in Offline Mode is performed with the EAS on the Tags enabled. The communication by the EAS function takes longer compared to Read/Write operations performed by other functions. The communication distance in the Online M o de should be checked using the actual commands.

3-2 Communication Modes

3-2

3-3

This Reader/Writer has five communication modes to be selected by each command corresponding to the number and/or state of Tags in the communication area.

Each mode is activated by specifying the communication in the command data.

3-2-1 Single Access

Single Access is used to read data from or write data on the on ly Tag th at exists in the Antenna Communication Area. The execution timing can be selected from Trigger, which executes immediately, Auto, which waits for the Tag to enter the communication area and executes, or Repeat, which repeats the execution for the Tag in the communication area.

Be sure to have only one Tag in the communication area. Multiple Tags in the Antenna Communication Area prevents the antenna from communicating normally.

：In the I.CODE1 Mode, the T ag is processed only once at the entry

into the communication area. It can be reprocessed once it is outside the area again.

3-2-2 FIFO Access

FIFO Access is used to read data from or write data on the Tags sequentially in the same order they entered the antenna communication area. (FIFO First In First Out).

The execution timing can be selected from Trigger, which executes immediately, Auto, which waits for the Tags to enter the communication area and executes, or Repeat, which continues to wait for the Tags to enter the communication area.

Since every Tag finished with communications is set to access prohibit, communications will be possible if only one Tag newly arrives in the communication area of the Antenna where m ore than one Tag exists.

An error results, however, if two or more Tags arrive in the communications area simultaneously. Once an access-prohibited Tag leaves the communications area, access to the Tag is enabled again.

Page 35

3-2 Communication Modes

3-2

3-4

3-2-3 Multiple Access

Multiple Access is used to read data from or write data on the Multiple Tags in the Antenna Communication area simultaneously. Communications with Multiple Tags in the communicat ions area is available. (This function is also called 1:N Access or Multiple Tag Simultaneous Access). The execution timing can be selected from Trigger, which executes immediately, or Repeat, which continues to wait for the Tags to enter the communication area.

In I.CODE1 Mode, specify the appropriate tag-number code in command data according to the number of Tags that exist in the communication area (refer to SECTION 5-2-5).

The Duplicate Communication Protecting F unction is useful for unstable Tags in the Antenna Communication Area (refer to SECTION 3-8 for details).

3-2-4 Selective Access

Selective Access is used to read or write data on sp ecified Tags among t he multiple Tags in the communication area.

In ISO Mode, communication with specific Tags is achieved by first reading the Tag UIDs (unique codes) in Multiple Access Mode and then by specifying them. It is recommended that the UID/SNR addition option of the Command Processing Procedure Setting should be used. It is especially convenient since data readouts and UID acquisitions are performed by a single command.

In I.CODE1 Mode, the Tag Detection Command that assigns numbers to the Tags in the communication area in Multi Access Mode is performed first, and then the Tag Designation Command that specifies the assigned numbers is performed to launch the communication with the specific Tags.

3-2-5 Fast Read Access: I.CODE1 Mode Only

The Fast Read Access speeds up the data readout in I.CODE1 Mode. Th e execution timing can be selected from Trigger, which executes immediately, Auto, which waits for the Tag to enter the communication area and executes, or Repeat, which repeats the execution for the Tag in the communication area.

The function operates the same way as in Single Ac cess mode when the Tag number code is set to 0; in other cases it is the same as in Multiple Access Mode.

[When the Tag number code is set to 0 (Single Access Mode)] By selecting the Trigger or Auto execution timing, the function executes

the same operation as that in normal single access mode but in a shorter period of time.

When the Repeat execution timing is selected, the function continuously returns data while the Tags are present in the communication area, this is useful in confirming the communication area.

[When the Tag number code is set to those other than 0 (Multiple Access Mode)]

The only execution timing availab le is Rep eat, since the functio n employs a simple version of the communication sequence, some Tag data may be unreadable under the condition where the respons es from the Tags collide frequently. In addition, the function processes and responds to the same Tags repeatedly while they are present in the communication area.

This function should be used when there is a low number of Tags in the communication area. When there are a greater number of Tags, the Multiple Access Mode should be used. The Duplicate Communication Protecting Function is useful to avoid multiple responses returned to the same Tag. (Refer to SECTION 3-8).

Note:

●For the I.CODE1 Communication Modes used under the conditions, where Multiple Tags exit in the Antenna Communication Area (Multiple Access, Selective Access, or Fast Read Modes), the Tag Number Code must be specified. The maximum number of Tags allowed in the communications area is set previously. (Refer to SECTION 5-2-5 for details).

3-3 Memory Check Function I.CODE1 Mode Only

3-3

3-6

By adding a check code to the data in the Tag, you can detect data errors due to the Tag memory (EEPROM) being overwritten, service life, and unforeseen factors.

The check code uses the CRC code of the g en eratin g polyn omi al X

+ X

+ X5 + 1.

A memory check is performed using the Memory Check Command (MC), which writes the check code, and the Memory Calculation Command (MK), which verifies the check code. In the check block defined using the header page and the number of pages, the target calculation area is the area except for the last page of the block, and the last page is the check code area. The check code uses two bytes in the check code area.

When a check code write command is sent, the CRC code for the data in the target calculation area is calculated, and written to the check code area. When the data verification command is sent, the CRC code for the data in the target calculation area is calculated, and compared with the data in the check code area. If these match, the number 75 is returned in the response code to show that the data is normal. If they do not match, the number 76 is returned to show that there is a data error.

Example: Memory check is performed when check block header page is 00 and the number of check blocks is 0B.

00 01

09 0A

3-3-1 Usage

After writing the data, calculate and write the check code using the Memory Check Command (MC), and before reading the data, verify the check code using the Memory Calculation Command (MK). You can detect data corruption in advance within the Tags that are not being accessed.

The Lock function protects data from being erased due to unintentional overwriting on the fixed data in the Tags.

■ Lock setting in ISO mode For the lock setting in ISO mode, you can write-protect any giv en areas by the page of Tag memory. If you execute Write command on a write-protect page, a write proc essing error (code:79) will occur. You can make the lock setting by executing the Lock command (LK) that enables access to the lock setting area. For the details, see 5-4-7 “Lock Setting: ISO Mode.”

■ Lock setting in I.CODE1 mode There is a lock setting area in the system area of I.CODE1 chip, and you can write-protect any given areas by page. If you execute Write command on the write-protect page, the write processing error (code:71) will occur. The lock setting consists of 12 bits of data in total, giving one bit to each page. Lock setting can be made by using the Lock command (LK). For the details, see 5-5-9 “Lock Setting: I.CODE1 Mode.”

3-5 Discriminating Access to Tag Function

3-5

3-8

The ID codes set in the Tags are utilized in identifying the target chips in the antenna’s application fields. Responses are r eturned only when the ID code in the command from the antenna and the ID code on the Tag are matched.

The factory default of the Reader/Writ er ID codes are all set t o 00h, which means communications are available regardless of ID codes on the Tags.

■I.CODE1 mode The I.CODE1 chip has two kinds of one-byte ID codes called the Family

Code and Application ID. The Tag ID code can be set/modified by the Write Command (WT) with the Family Code/Application ID area (FF page) specified.

The ID codes for the Reader/Writer can be set/modified by the Reader/Writer Family Code Setting (FC)/Reader/Writer Application ID Setting (AI) Command.

Reader/writer setting (1)

This setting enables communication with Tag A, B, and C, as both of the family code and application ID are set to “00h.”

Reader/writer setting (2)

This setting enables communications with Tag A and B as their family codes match. Communication with Tag C is not possible. This identification code has nothing to do with identifying Tags as the application ID is “00h.”

Reader/writer setting (3)

The communication with Tag “A” is possible as the family code and application ID match. The communication with Tag B and C are not possible.

■ISO Mode Both the I.CODE SLI and ISO/IEC Chips have a one-byte ID code called

AFI (Address Family Identifier). To use this function, the AFI’s must be set for the Reader/Writer and Tags, and the function must be enabled on the Reader/Writer as well. The Tag ID codes are set/modified using the System Write (SW) Command. The ID codes for the Reader/W riter are set by the Reader/Writer AFI Enable/Disable Changeover (AE) Command or the Reader/Writer AFI Value Setting (AF) Command.

Reader/writer setting (2)

This setting enables communication with Tag A and B of which the AFI’s 4 least significant bits “Ah” match. As the 4 most significant bits are “0h,” the part of this identification code has nothing to do

with identifying a Tag. Reader/writer setting (3) The communication with Tag “A” is possible as AFI matches.

3-6 External I/O Function

3-6

3-9

The I/O connector has three external input ports and four external output ports to which such devices as sensors or actuators are connected to build a more efficient system.

The external output may be de dicated to the antenna control, de pending on the Reader/Writer settings.

3-6-1 External Input

[Online Mode] The status can be obtained by the I/O Control Command (CC). Sequenced

operations such as those for starting and terminating the communication with Tags by external triggers are available.

[Offline Mode] Not available. The I/O Control Command (CC) is rejected. To per form th e

function, the mode must be switched to the Online Mode by the Stop Command (ST).

3-6-2 External Output

[Online Mode]

The output status can be modified or read-out by the I/O Control Command (CC.) Read-out data can be evaluated by the host and output as a control signal for Lamps or sounds.

When the I/O Automatic Changeover Setting is enabled, the external outputs 3 (OUT3) and 4 (OUT4) are dedicated to the antenna control and thus unmodifiable. However, the output status can be read-out.

[Offline Mode]

The external output is dedicated to the control from the Reader/Writer in this mode. Modification/Reading out of the output status by the I/O Control Command (CC) is unavailable.

The external output 1 (OUT1) is turned ON for a specified period of time (modifiable) when Tags with the uncanceled EAS is detected. The external outputs 3 (OUT3) and 4 (OUT4) are dedicated to antenna control when the I/O Automatic Changeover setting is enabl ed.

Page 41

3-7 EAS Function

3-7

3-10

The Reader/Writer supports the EAS (Electronic Article Surveillance) system applied for anti-theft and other devices. The Reader/Writer identifies the unique data string returned by the EAS-bit enabled Tags and detects the existence of the Tags in the communication area . Multiple EAS-bit enabled Tags that exist simultaneously ca n also be d etected. The Reader/Writer stops detecting the Tags by disabling the EAS bit on the Tags. This is useful in preventing unauthorized removal of properties or giving caution.

The function operates in either Online Mode, where the function is executed by the commands issued by the connected host, or Offline Mode where the function is executed by the Reader/Wri ter alone.

[Offline Mode] In the Offline Mode, the EAS-bit ena bled (non-disabled) Tags are

continuously detected. When the EAS-bit enabled Tags enter the Antenna Communication Area and their EAS-response concordance rate exceeds the specified value (=EAS thr e shold), the external output 1 (OUT1) will turn ON for the specified time. The operation state is visibly identified by the OUT1 LED light. The EAS thresh old and external output time are specified by the Offline Mode Sett ing (FL) Command.

●EAS threshold The Tags return 256-bit fixed data. The concordanc e rate at which the Tag is recognized as one with non-disabled EAS (EAS-bit disabl e processing is not performed) is specified by a percentage. The smaller the concordance rate, the more lax the criteria bec om es. The init ia l thresh old is 75%.

●The ON-time of the external output 1 (OUT1) The ON-time is specified according to the output time of the lamp or

buzzer. The initial output time is 500ms.

[Online Mode] The EAS Check (EA) Command is executed from the host. (Refer to

SECTION 5-5-10). The EAS-response concordance rate is retur ned, which is compared to the threshold in the host and evalua ted for the exi stence of the EAS-enabled Tags.

■EAS Setting for the Tag The EAS on the Tag is enabled by a specific command that enables

EAS-bit. For the ISO/IEC chip (I.CODE SLI chip), it is done by the System Write (SW) Command and for I.CODE1 chip, it is done by the EAS Setting (ES) Command.

3-8 Duplicate Communication Protecting Function

3-8

3-11

The Duplicate Communication Protecting Function prevents the command that processes multiple Tags serially from performing multiple Read/Write processing for each Tag. This function controls the command so that it performs the processing only once per Tag and returns a single response, even in situations where a Tag is recognized more than once as shown below. The processing loa d is reduced because the response receiving or duplication check by the host is unnecessary. The communication performance speed is also improved since unnecessary processing is eliminated in the following:

1. The situation where the Tag enters the Antenna Com munication Area several times due to its vibration, irregular operatio n, or stop on the boundary, or because the Tag is in the antenna’s side lobe area.

2. The situation where the Tag is stopped in the boundary zone or enters the Antenna Communication Area several times because of the moved antenna.

3. The situation where the Tag passes an antenna with a discontinuous communication area such as the gate antenna.

The enabled function is activated when the commands using the following communication modes are executed:

・FIFO Repeat Mode (FR) ・Multiple Trigger Mode (MT) ・Multiple Repeat Mode (MR, UR[I.CODE1 Only]*)

When the function is enabled, the unique number (UID/SNR) given to the processed Tag is recorded in the table of the proc essed Tags after the comm and has been executed. When a new Tag is detected and its UID/SNR is obt ained, the system refers to the table and processes the Tag only when the UID/SNR is not found in the table. After the Tag has been processed normall y, the system records the UID/SNR in the table. The table is initialized at the start o f com mand.

* As to UR, the page on which the processing is started must b e FB, and the pag es must be 2 and more.

The function is set by the Duplicate Communication P r otecting Function Setting (MX) Command (disabled by factory default.) To enable the function, specify the maximum number of UID/SNRs recorded in the table of the processed Tags. The number of tables can be selected from 1, 4, 8, 16, 64, 128, or 256. Usually, the closest number above the maximum number of Tags that can co-exist in the communication area of the antenna being used is spec ified.

Example) When the maximum number of the co-existing Tags are 6: The number of tables = 8

1: Tag０ 2: Tag１ 3: Tag２ 4: Tag３ 5: (Vacant) 6: (Vacant) 7: (Vacant) 8: (Vacant)

The table of the processed Tags:

In this case, Tag 0 is not proc essed for re-entry in the commun ication ar ea. When the Tag 4 enters the area  it is processed and recorded in row 5: of the table.

4-2

The V720-series RFID system has two operation modes: Offline Mode and Online Mode. The functions

and control methods by the host vary, depending on the Operation Mode. One of the two modes must be selected at system setup.

4-1-1 Offline Mode

In the Offline Mode, the EAS-enabled Tags (the EAS function mounted on the Ta gs is not disabled) are always detected (1). When the EAS-en abled Tags enter the antenna communication area, the output results (OUT1) turns ON for the specified time (2). The control from the host is unnecessary. The PCs used for setup are connected as needed when the operating conditions must be specified. Some ou tpu ts are exclusively us ed for antenna c ontrol, depending on the settings.

●Detecting Tags In the state where the EAS-enabled Tags (the EAS function mounted on the Tags is not disabled), are being detected, the COMM LED flashes in this state.

●Detection of the EAS-enabled Tags In the state where the EAS-enabled Tags are present in the Antenna Communication Area. OUT1 turns ON for the specified time. OUT1 stays ON while the Tags are present in the area.

4-1-2 Online Mode

Communication with Tags (2) is performed according to the command (1) from the connected host. The result is returned to the host as a response (3). The I/O can be read or controlled using commands. The input can be used as a command execution trigger, and the output can be used as a result-based control signal for peripherals. Some outputs are exclusively used for antenna control, depending on the settings.

●Command Standby State The Command Standby State is where the Reader/Writer is not processing but can accept any command other than AK or NK, which are used for ACK/NACK control. When the Reader/Writer accepts a command, it enters the command processing state.

●Command Processing State When a command is accepted, other commands are ignored until the accepted command has been processed. However, the Stop (ST) and Reset (XZ) Commands are always accepted. When a command that performs continuous processing is executed, the processing state continues until completed or stopped. The COMM LED is lit (flashed) while communication with the Tags is in progress.

The Reader/Writer enters a special command processing state in the following situations, although it is not actually communicating with the Tags. The COMM LED is not lit in these cases. ・After the commands have been executed in FIFO trigger or FIFO auto mode

FIFO continuation state where the antenna oscillates continuously: Only the FIFO access commands are accepted. ・After the Tag Detection Command has been executed (I.CODE1 Mode only).）

Selective state where the simplified numbers of Tags are stored, only the Tag specification commands are accepted.

●Normal/abnormal completion of command processes The NORM LED is turned on when the command from the host has been completed normally, and ERROR LED is turned on if the command has been completed abnormally, for a short period of time at the returning of the response.

By setting the Test Mode, the communications between the Antenna and T a g can be tested without connecting the host. You can exit the Offline Mode by connecting to the host and sending a Stop Command (ST)

●Communication test between the Reader/Writer and the host

By using Test Commands(TS), the communications between the Reader/Writer and host can be tested. This test allows the checking of the cable connect ion and the processing operation of communications before the trial operation of the whole system. It is recommended that RS-232C be connected to COM2 where the communication condition is fixed.

・Prepare a simple communications program on the host and transmit Test Commands.

・If the communications line is normal, the Reader/Writer returns the data received.

The Reader/Writer has been designed for the user to make all t he settings by issuing commands from the host. The user can use either th e COM1 or COM2 port to make settings. However, we recommend use of the COM2 port because its communications settings have been fixed at factory to survive a power reset.

In order to fix the information set for the Reader/Writer to survive a power reset, it is necessary for the user to execute the setting write command (EW) (refer to 10) in 5-７-14 of Section 5). (This does not apply to the communications settings for the COM2 port).

Precautions on setting modifications

●The execution of the setting commands only modifies the S-RAM (volatile memory) on the Reader/Writer. The modifications are not reflected immediately; they are reflected only after the Reset Command (XZ) has been executed.

●To apply the modified settings at the next startup, fix the settings and reset the power supply. If the settings are not fixed, the modifications will be reset to the original status after the power supply reset. This does not apply to the communication settings for COM2.

●If Reset Command (XZ) is executed without fixing the settings, the settings are reset to original status after the power supply reset.

●The default mode is Offline mode. T o change the settings, the mode must be switched to Online mode. Connect the

host and execute Stop Command (ST.)

4-4

4-10

The V720S-BC5D4 Reader/Writer is a highly reliable control device withstanding tough environments. In order to ensure the full, reliable performance of the RFID system, however, obs erve the following.

4-4-1 Installation

Do not install the Controller under the following conditio ns.

• The ambient temperature is not within a range between -10℃ and 50 ℃ or there are radical temperature changes resulting in condensation.

• The humidity is not within a range between 35% and 85%.

• There is corrosive gas, flammable gas, dust, salt, or metal powder.

• The Reader/Writer is affected by direct vibration or shock.

• The Reader/Writer is exposed to direct sunlight.

• Oil, or chemical is sprayed onto the Controller.

• Do not install the Reader/Writer close to heaters, transformers, or

resistors that radiate excessive heat.

• If power lines or high-tension lines with large currents are located close to the Reader/Writer, be sure to test the Reader/Writer carefully and make sure that wires connected to the Reader/Writer are not affected by the noise of power lines or high-tension lines.

Note

●Be sure to abide by the above before installing the Reader/Writer and carefully test the Reader/Writer.

●Be sure to wire antenna cables separately from other cables. For the antenna cable, be sure to u se V720-A41

3.35M or V720-A41 10.33M that is specially designed for this product. Using any other cable may affect adversely the communications performance, waterproof performance, etc.

● For wire power and I/O cables as well, wire them separately wherever possible in order to avoid malfunctions.

Caution

Ensure that a solid (Class D) grounding is established for the “GR” on the Reader/Writer power connector.

Page 53

4-5 Mounting Method

4-5

4-11

The Reader/Writer must be mounted using a mounting plate. When mounting, be sure to secure it onto the mounting plate with M6 screws, spring washers and flat washers.

Do not apply organic solvent, e.g., screw lock solvent, to the screws to secure the Reader/Writer. If you do, the Reader/Writer body and the mounting plate may be damaged.

Note

● Use 24 VDC to supply power to the Reader/Writer. When you use the r ecommended power su pply, S82K-03024, and a cable with a thickness of A WG16, the cable can be extended to 7 meters at maximum. If a longer power wire is desirable, use a power supply with remote sensing function.

● The maximum power consumption of the Reader/Writer is 25 W. An inrush current of approximately 30 A at 24 VDC, however, flows when the Reader/Writer is turned ON. Take this into consideration when preparing the power supply.

● Provide a power wire with a thickness of AWG16 in order to prevent the dropping of voltage. It is recommended

that twisted-pair wire be used for the power line. The thickness of AWG16 is the maximum wire diameter that can be used with the power connector of the Reader/Writer.

● Use Class D grounding (previous Class 3 grounding) for the Reader/Writer for improved noise

resistance.

● Use the ferrite core enclosed to the Reader/ Writer for the 100VAC side of the recommended compact

DC power supply S82K-03024.

WARNING

● Be sure to connect to a power supply with a maximum power supply capacity of 24V 4.2A (100 W) or less.

In case a short-circuit failure should occur within the Reader/Writer, a burnout in the power cable may result.

Attach the ferrite core (accessory) for the cable to supply 100VAC.

Note

When you connect more than one Reader/Writer, give special attention to communications timing between Reader/Writers. To ensure proper timing, you will ne ed to per form both th eoret ical calc ulati on of timing and verification of communications on real machines.

1) The Reader/Writers cannot operate simultaneousl y except through polling-related commands. This means that, even when you connect more than one Reader/Writer, only one Reader/Writer can communicate with the host at a time. Multiple Reader/Writers can access the host only in a time-phased manner.

2) When you use an Auto command, the Reader/Writer will not return a response but continue to wait if there are no Tags in the communications area. In this state, if you send a command to another Reader/Writer, no command will be accepted until a response is returned. To avoid this, you must abort the Auto command using the STOP command before sending any command.

3) Polling-related commands do not support any commands but Auto commands. These commands are not available in Multiple Access Mode (which permits access to multiple Tags) to avoid processing complexities.

5-1 Control by Commands

5-3

5-1-1 Control by Commands

The Reader/Writer operation is controlled by the commands from the connected host. The result of the command execution is returned as a response. In Online Mode, all the operations, such as Tag-data Reading/Writing, Tag-function setting, operating condition setting, or Reader/Writer function control, are controlled by the commands. In Offline Mode, the Reader/Writer functions controlled by the commands are restricted to those controlled by Stop and Reset commands. The operating conditions for Offline Mode are set in Online Mode.

5-1-2 Command-Response Flow

In Online Mode, the host sends an instruction command and the Reader/Writer returns the result as a response. The command-response flows vary, depending on the types of commands and specified communications, as shown below.

1-to-1 Response

One response is returned per command for Single Trigger (ST), Single Auto (SA), FIFO Trigger (FT), FIFO Auto (FA), UID Select (SL), or Tag Designation is specified for the command that performs the communication with the Tag, or when a command that does not perform the communication with the Tag is specified.

Multiple Response

Multiple Responses are returned per command for Single Repeat (SR), FIFO Repeat (FR), Multiple Trigger (MT), Multiple Repeat (MR), or Tag Detection (LT) is specified for the command that performs the communication with the Tag.

5-1-3 ACK/NACK Control

When using ACK/NACK control, if the host does not receive a normal response, the Reader/Writer will resend the response by either (1) when the host sends a NACK command to the Reader/Writer or (2) when there is no response within a set period of time. Consequently, a response can be received without communicating with a Tag again. The host checks that responses have been received normally using the ACK/NACK commands, so response data can be communicated dependably.

■Using ACK/NACK Control If the host receives a normal response, it sends an ACK command to the Reader/Writer. The Reader/Writer judges that the host has received a normal response, and enters a command-waiting state. If, after the Reader/Writer has sent the response, an ACK is not received normally within the time set using the time out setting, or a NACK is received, the Retry Flag is set and the last response is sent again. The maximum number of response retries that can be made is nine.

5-2 Control Procedures for Each Communication

5-2

5-5

The operating sequences including the communication with the Tag or timing for returning the response vary, depending on the communication mode. The communication mode is set by specifying the communication mode in the command data. The access and mode specified as the communication settings must be those specifiable for each Tag status in the specified antenna’s communication area or the connection topology with the host. This section describes these access and mode settings.

5-2-1 Single Access

In single access, a single Tag can exist in the communications area. The presence of two or more Tags in the communications area causes a communications error.

5-2-1-1 Single Trigger mode

Single Trigger mode is used when a single Tag is present in a resting condition in the antenna communication area. If the Tag does not exist in the antenna communication area, No Tag Error is returned.

5-2-1-2 Single Auto Mode

The Reader/Writer waits until the Tag has entered the antenna communication area and executes the command it received from the host. When the Reader/Writer receives Auto Command, it enters the busy state until the communication with the Tag has been completed, during which it does not accept any commands other than Stop Command (ST) and Reset Command (XZ).

5-2-1-3 Single Repeat Mode: ISO Mode

The Reader/Writer waits for a Tag to enter the R/W Antenna’s communications area. Every time a Tag enters the communications area, the Reader/Writer communicates with the Tag and returns a response. It is not until communications are stopped by the Stop(ST) or Reset(XZ) command that the Reader/Writer accepts the next command.

Operation in I.CODE1 mode

●Do not operate the function in I.CODE1 mode. If a function equivalent to ISO mode, i.e., a function that

always returns a response, is required for the area confirmation and other purposes, a single command (Tag code = 0) by Fast Read Access should be used.

(If the function is executed in I.CODE1 mode, the Reader/Writer will perform the process only once at the Tag’s entry to the communication area and return a response. Multiple Tags in the communication area may result in a response with abnormal read data).

5-2-1-4 Polling Auto Read

If an Auto command is used when a single host controls more than one Reader/Writer, the communications path between the host and one of the Reader/Writers to which the command is sent becomes busy, disabling the host to control other Reader/Writers. On the other hand, when a Polling Auto command is sent instead, the Reader/Writer returns a response according to the request from the host. The communications line with the host will not remain busy, allowing the host to send a command to other Reader/Writers. When Polling Auto command is executing, the only commands accepted and executed are Polling Check (PC), Polling End (PE), Reset Command (XZ), and Stop Command (ST). An example of Polling Auto Command executed for two Reader/Writer devices are shown below.

(1) The host sends the Polling Auto

Command to the Node 1 Reader/Writer.

(2) Immediately after command reception,

Node 1 returns a response indicating the acceptance of the command.

(3) The host sends the Polling Auto

Command to Node 2.

(4) Immediately after command reception,

Node 2 returns a response indicating acceptance of the command.

(5) The host inquires after the progress of

the communications processing or stops the Polling Auto processing using the Polling sub command. When the communications processing is not yet complete, the Reader/Writer returns a response indicating unfinished processing in reply to the inquiry of the Polling sub command.

(6) The Node 1 communicates with a Tag

entering the communications area.

(7) Node 1 returns a response indicating

the results of communications with the Tag in reply to the Polling subcommand.

5-2-2 FIFO Access

In FIFO (first-in, first-out) access, communications with Tags entering the communications area one after another are carried out in sequence. Once communications with Tags are completed, access to them is prohibited. Consequently, even if Tags with which communications are already completed exist in the communications area, a newly entering Tag can be accessed. Simultaneous entering of two or more Tags causes a communications error. Once an access-prohibited Tag leaves the communications area, access to the Tag is enabled again.

5-2-2-1 FIFO Trigger Mode

FIFO Trigger Mode is used for communications when the Tag is present in a resting condition in the antenna communication area. The Reader/Writer prohibits access to the Tag after the communication has been completed, and keeps the antenna oscillated to maintain the FIFO access. Under such conditions, the Reader/Writer can issue another FIFO command and communicate with the next Tag that enteres the communication area, where the previous Tag with which the communication has been completed is still present. (The commands other than FIFO Access are rejected). When there are no accessible Tags in the antenna communication area, the No Tag Error is returned.To exit the FIFO state, execute Stop Command (ST).

Under such conditions, the Reader/Writer can issue another FIFO command and communicate with the next Tag that entered the communication area where the previous Tag with which the communication has been completed is still present. (The commands other than FIFO Access are rejected). When the Reader/Writer receives Auto Command, it enters the busy state until the communication with the Tag has been completed, during which it does not accept any commands other than Stop Command (ST) and Reset Command (XZ). To exit the FIFO state, execute Stop Command (ST).

The Reader/Writer waits until the Tag has entered the antenna communication area and starts communicating. It communicates with the Tags serially as they enter the antenna communication area, and returns the responses. When the communication has been completed, the Reader/Writer makes the Tag inaccessible, so that it can communicate with the next Tag that entered the area although the Tags with which the Reader/Writer has completed the communication are still present in the same area. This state continues until the communication has been terminated by Stop Command (ST), or Reset Command (XZ), and other commands are rejected.

When the Tag is on the boundary of the communication area or enters the communication area more than once because of swing, the Tag may be processed more than once, or some Tags may not be processed. In this case, enable the Duplicate Communication Protecting Function (Table number = 1). The function will prevent the Reader/Writer from communicating with the Tags already communicated with, and allows proper and sequential Tag processing.［Software Ver 1.20 and higher only］

Note

To send another command from Repeat Mode, be sure to use either the stop command or reset command, and make sure that the Reader/Writer has finished processing commands and is in command waiting status before sending the new command.

5-2-3 Multiple Access

In Multiple Access, the Reader/Writer can communicate with all of the multiple Tags present in the antenna communication area. In I.CODE1 Mode, the Tag code corresponding to the number of Tags present in the communication area must be specified. For the Tag number specifications, refer to SECTION 5-2-5.

When the Tag is on the boundary of the communication area or enters the communication area more than once because of swing, the normal operation may be interrupted because the Tags are processed more than once. In this case, it is recommended that UID/SNR addition setting be enabled to evaluate the Tags on the host side. In addition, one processing per Tag is available by enabling the Duplicate Communication Protecting Function. For Duplicate Communication Protecting Function,, refer to SECTION 3-8.

5-2-3-1 Multiple Trigger Mode

Read Command (RD) Write Command (WT) with UID/SNR addition setting enabled

(Excluding I.CODE1 Mode). At the reception of the command, the Reader/Writer communicates with all the Tags in the communication area and returns communication results with each Tag, as responses. After communicating with all the Tags, it returns Detection End Response (Response Code: 72). When no Tag is present in the communication area, it returns to Detection End Response (Response Code: 72).

In I.CODE1 Mode, when the Reader/Writer could not communicate with all of the detected tags or when it detected non-processable Tags during the processing sequence, it returns a warning code (Code: 0□) as

Response Code. (Refer to SECTION 5-3-7-2).

In Write Command (WT) with UID/SNR addition setting disabled (in I.CODE1 Mode, the command with UID/SNR addition setting eabled is also covered), the Reader/Writer communicates with all the Tags in the communication area on receiving the command, and returns the results of the communications with each tag as a response. At the completion of communicating with all the Tags, it returns Detection End Response (Response Code: 00) once. The number of Tags with which the communication has been normally completed is added to Detection End Response. When no Tag is present in the communication area, it returns Detection End Response (Response Code: 72).

In ISO Mode, if the communication with the detected Tag failed, the Reader/Writer returns an error response immediately and moves on to process another Tag. At the completion of communicating with all the detected Tags, it returns the Detection End Response and terminates the command processing.

In I.CODE1 Mode, the Response Code is set to 00 only after the communications with all the detected Tags have been completed successfully. When the number of Tags detected exceeds the number specified by the Tag code in command data, the Response Code is replaced with a warning code (Code: 0□), (Refer to SECTION 5-3-7). If data writing process in even one Tag has failed, the Reader/Writer returns to Write Process Error (Response code: 71), and terminates the command processing.

Note:

In processing Multi-Trigger Command, some Tags may not be processed due to their conditions (including the distances between the antenna and Tag, or those between the Tag and another Tag). The operating system must be configured to check the number of processed Tags based on the number of returned responses or normally processed Tags, and match them against the actual number of the Tags.

5-2-4 Selective Access

Selective Access is a function to communicate with the specified Tags among multiple Tags in the antenna communication area. The processes vary depending on the Reader/Writer’s mode.

5-2-4-1 ISO Mode

First, the Reader/Writer reads out the UID of the Tag in the communication area using Read Command (in multiple processing modes). The UID is readable when UID/SNR addition setting option is enabled in advance using the respective command (SN). When the UID is already identified, the execution of Read Command can be skipped. Then, the Reader/Writer communicates with the specified Tag based on the obtained UID.

(1) The Reader/Writer reads the UID of the Tag using Read Command.

It reads out UID data of the Tag by executing a Multiple Trigger Mode command with its

UID/SNR addition setting enabled.

(2) The Reader/Writer communicates with the specified Tag (No. 2 in the figure below) by

specifying the UID obtained in 1 using UID Select Read/Write command.

The ReaderWriter communicates with the Tag specified by the UID. For UID Select Command, specify SL for the communication, and specify the UID of the communication target Tag in the UID area in hex number, 123.

Note:

Some Tags detected by UID read (Tag detection) may not be communicated with Selective Access mode using UID Select (Tag designation) command, depending on the Tag conditions (the distances between the antenna and tag, or those between the Tag and another Tag). This is especially true when the Tag exists in the boundary area of the communication area. The operating system must be configured to check the number of detected Tags against the number of Tags the Reader/Writer communicated with (or the number of the actual Tags).

(2) The Reader/Writer communicates with the

Tag.

The Reader/Writer communicates with the Tag when it is in the Reader/Writer antenna communication area.

After the Reader/Writer has communicated with all the Tags in the communication area, it returns the Detection End Response.

The Reader/Writer receives UID Select Command with the UID of the communication target Tag added.

The communication with the Tag with the specified UID is processed.

5-2-4-2 I.CODE1Moed

After allocating the Temporary numbers to the Tags in the communication area using Tag Detection Command, the Reader/Writer communicates with the Tags based on the allocated numbers. The Tag code must be specified as command data according to the numbers of the Tags present in the communication area. For Tag number specifications, refer to SECTION 52-5.

1. Numbers are allocated to the Tags by Tag Detection Command.  Tag Detection Command, the state enters the Select State, where the mapping of the

Tags in the antenna communication area and their Temporary numbers are stored. In Select State, all the commands are rejected except the Tag Designation Command.

The

Select State is valid until Stop Command (ST) has been executed.

2. After allocating the numbers to the Tags, the Reader/Writer communicates with the specified Tag (No.2 in the figure below) using Tag Designation Command.

The ReaderWriter communicates with the Tag specified by the Temporary number. It can communicate with the Tags repeatedly in the Select State.

Tag Detection Command/Tag Designation Command

For Tag Detection Command, specify LT as the communication method of the command. For Tag Designation Command, specify 00 to 7F as the communication method of the command. (To specify the Tag with Temporary number 1, specify 01).

5-2-5 Specifying a Tag Code: I.CODE1 Mode

The timeslot setting is the setting in the command frame when communicating with multiple Tags simultaneously using Multi-system commands. This setting must be set according to the number of Tags with which to communicate simultaneously. Refer to the table below for the relationship between the number of Tags and this setting.

Specifying a Tag

Code

Max. No. of Tags with which simultaneous

communication is possible

〜2

〜4

〜8

〜16

〜32

〜64

〜128

Example: If the number of Tags is seven, select Tag Number setting 3.

Note:

● For the Multi Trigger(MT) and the Multi Read(MR), if more Tags than have been set using the timeslot setting

enter the communications range, a "70" error (warning) may occur. (e.g., When the timeslot setting is "2" and there are five Tags in the communications area.)

●For the Special Read (refer to 5-2-1-6) command, the anti-collision process is not performed. Therefore, read

data will be returned even If there are more Tags than the timeslot setting in the communications area.If a collision occurs, such data will not be returned.

● The higher the timeslot setting is, the longer the communications time is required. Consequently, setting a

higher timeslot setting than required for the number of Tags in use unnecessarily lengthens communications time, so select a suitable setting.

I.CODE1 System Area

From Page FD to Page FF is a system area for write-protect and QUIET/EAS settings. Depending on the content of write data, a Tag may become write-protected or inaccessible, so be sure to understand these pages fully before use. It is strongly recommended that data be re-written using a command dedicated to system area re-writing rather than Write Command (Refer to SECTION 5-5). Re-writing data when the Tag is in an unstable communication area may destroy data in the system area, interrupting the communication with the Tag. Be sure to re-write data while the Tag is in a stable communication area.

：In Fast Read Access, multiple Tags can be read in the same way as in Multiple Repeat mode by

setting the Tag code other than 0 and specifying UR as the communication method. However, data is repeatedly read while the Tag is in the communication area. (Refer to SECTION 3-2-5). When UT or UA is specified as the communication method, the anti-collision processing (the operation to prevent the collision of the response returned by the Tag), it is not performed even if a number other than 0 is specified as the Tag code. Therefore, if a collision (of the response) takes place, its Tag data cannot be read. It is recommended that the command be used in Multiple Access mode (MT/MR).
