V700-H01 and V700-H02 (RFID) R/W Antennas

V700-CD1D-V3 V700-CD2D-V3

The V700-CD1D-V3/V700-CD2D-V3 incorporates an RS-232C interface, thus connecting to personal computers and Programmable Controllers (PCs) over RS-232C to process large amounts of data flexibly with simple commands.

The V700-H01 is a standard antenna that is 250 by 200 mm in size, ideal for long-distance communications, and ensuring a minimum communications distance of 250 mm. The V700-H02 is a wide-field antenna th at i s 650 by 200 mm in size. Compared with the V700-H01, the V700-H02 provides rough positioning and better communications with ID Tags moving at high-speed.

V700-D23P31 and V700-D23P41 (RFID) Tags

Highly Functional RFID System

Ease of Use

The V700-D23P31 Data Carrier has a memory capacity of 240 bytes. It is coin– shaped and measures only 20 mm across. It resists water , chemicals, and other elements of harsh environments and can hold data for 200 hours at 180°C. The V700-D23P41 Data Carrier also has a memory capacity of 240 bytes. It is barshaped and only 3.9 mm in diameter and 25 mm long. It mounts easily in drill holes or other tight locations, simplifying mounting to machines or products. It holds up under harsh environments and can hold data from –40 to 110°C, is highly resistant to water and can be stored at a wide range of temperatures.

The RFID System operates in either multiple, simultaneous access mode or FIFO (first-in, first-out) read/write mode. In multiple, simultaneous access mode, if there is more than one ID Tag in the communications area, the RFID System reads and writes data from and to the all ID Tags at one time. In FIFO read/write mode, the RD-ID System reads and writes data to one ID Tag after another as they come into the communications area.

The C200H-PRO27-E Programming Console (sold separately) can be connected to the RFID System over the V700-P10 Programming Console Conversion Cable (sold separately). With the Programming Console, the communications condition of the System can be monitored on-line. Furthermore, the error log of the System and the ambient noise measurement in the communications area can be read with ease. All these functions make it possible to start up the System quickly and improve the efficiency of on-site maintenance work on the System.

V700-D23P31 can be, however, in normal operation (i.e., the V700-D23P31 located in the communications area) at a maximum of 70°C. This means the temperature of the ID Tag itself in operation must not exceed 70°C. Before using the ID Tag, conduct some tests and check that the temperature of the ID Tag itself in operation is 7 0 °C maximum. If the temperature of the ID Tag is 180°C, it normally takes a period of one minute for the temperature to drop to 70°C for an ambient temperature of 2 5 °C. Take this into consideration when cooling down the ID Tag.

SECTION 3

Functions

3-1 Single, FIFO Read/Write, and Multiple, Simultaneous

Access Functions

Three communication modes are available depending on the number or state of Tags in the communication area. Commands can be used for selecting one of them. Refer to Section 5 Communications Functions for details.

3-1SectionSingle, FIFO Read/Write, and Multiple, Simultaneous Access Functions

Single Mode

FIFO Read/Write Mode

In this mode, only a single ID T ag can be in the communications area, otherwise a communications error will result.

In the FIFO (first-in, first-out) read/write mode, the RFID System reads and writes data to and from each ID Tag coming into the communications area one after another. S ince every ID Tag finished with communications is set to access prohibit, communications will be possible if only one ID Tag newly arrives in the communication area of th e A n t e n n a where more than one ID Tag exists. An error, however, results if two or more ID Tags arrive in the communications area simultaneously. When the access-prohibited Tag moves out of the communications area, communications will become possible again.

Multiple, Simultaneous Access Mode

In this mode, communications with all ID Tags in the communications area can be made on receipt of the command.

Note In FIFO read/write mode, make sure that multiple ID Tags do not arrive in the

communications area together , otherwise a communications error will result and further communications will not be possible until there is only a single ID Tag in the communications area.

3-2 Write Protect Function

The write protect function is a protective function that is provided to prevent permanent data, such as product information and pallet numbers saved to data carriers from being lost through being accidentally overwritten.

Any areas can be write-protected in page units by setting the protection information in the ID Tag. If a WRITE command is executed for a page that has been set for write protection, a protect error is generated. The data protection area is comprised of one bit per page, for a total of 30 bits. To execute write protection, use the WRITE PROTECT (WP) command to set the bit for the relevant page. In the same way, release the write protection by clearing the bit.

3-3 Memory Check Function

By adding check codes to data in ID T ags, it is possible to detect errors i n the data contents resulting from accidental causes or deterioration as the EEPROM reaches the end of its service life. For the check code, a CRC code calculated by the generating polynomial X

A memory check is executed by using the MEMORY CHECK (MC) command to write the check code, and the MEMORY CALCULATE (MK) command to verify the check code. The calculation area is the portion of the check block specified by the first address and the number of bytes excluding the last two bytes. The check code area is the last two-byte portion.

When a command to write a check code is sent, the CRC code of the data in the calculation area is calculated and written to the check code area. When a command to verify the data is sent, the CRC code of the data in the calculation area is calculated and compared with the data in the check code area. If they coincide,

3-4 Mutual Interference Preventive Function (Synchronous

Function)

This function can reduce the mutual interference distance of each Antenna. If two or more Antennas are close to one another, they will not operate properly

due to mutual interference. It is possible to reduce the mutual interference distance of each Antenna by connecting the Controllers together over synchronous cables through the SYNC terminal as shown below. In this example, one of the Controller connected in series is set as the Master and the others are set as Slaves. Be sure to set the terminating resistance of the Controller at each end to ON and that of other Controllers to OFF. A maximum of 32 Controllers including the Master and 31 Slaves can be connected within a total cable distance of 300 m maximum. Refer to page 35, DIP Switch Settings, page 44, SYNC signal

Wiring, and 8-6 Mutual Interference of Antenna for the settings, cable connec- tions, and mutual interference distance in detail.

3-4SectionMutual Interference Preventive Function (Synchronous Function)

Note 1. Be sure to set only one of the Controllers as the Master and other Controllers

as Slaves in synchronous operation, otherwise the RFID System will not operate.

2. Be sure to set the terminating resistance of the Controller at each end to ON and that of any other Controller to OFF, otherwise stable operation of the RFID System will not be possible.

There are two types of synchronous functions to reduce the mutual interference distance of each Antenna. These functions are called R/W (read/write) synchronous and RO (read-only) synchronous functions. Both READ and WRITE commands are available to the R/W synchronous function. Only the READ command is available to the RO synchronous function. The RO synchronous function requires a shorter communications time than the R/W synchronous function. Refer to 8-4 Communications Time and page 35, DIP Switch Settings for details.

Precautions

Make sure that all Controllers connected are in the same synchronous type (i.e., in R/W synchronous operation, OR synchronous operation, or not in synchronous operation), otherwise the communications of all Controllers may be affected.

3-5 Energy-saving Mode

The RFID System can be set to energy-saving mode. In case commands can be issued only during communications, the Antenna

power can be shut down to reduce the total power consumption of the RFID System. In energy-saving mode, the power consumption of the RFID System is approximately 30% of that in normal operation.

If the Controller is set to energy-saving mode, the Antenna will have output only at the time of communications. This mode is available while a communications command is issued to select the single trigger, single auto, or multi-trigger option.

3-6 Long-distance Mode and Stable Communications Mode

(Communications Distance Setting)

Long-distance Mode

Stable Communications Mode

In order to perform long-distance communications, the RFID System automatically selects the amplification factor when the Antenna receives signals from the ID Tag. If the ID Tag is far, the amplification factor increases automatically in order to receive the weak signal of the ID Tag.

If there is excessive noise (particularly, air-conditioner noise), the automatic selection of the amplification factor should be suppressed. If this automatic selection is suppressed, the RFID System cannot communicate with far ID Tags but the RFID can perform stable communications even under an environment where noise is prevalent.

The RFID System allows a selection of either long-distance mode (automatic selection of amplification factor) or stable-communications mode (no change in amplification factor). Refer to page 35, DIP Switch Settings for details.

3-8 Error Logging Function

The error log data of the RFID System can be read on-line through the Programming Console.

Two types of error log data can be read, which makes it possible to analyze system errors.

1. Latest Error Log

2. Statistic Error Log

The Controller keeps a record of errors resulted in RUN mode after the Controller is turned ON. The Programming Console can read information on these errors, thus making it possible to find causes of errors. The Controller keeps a record of a maximum of 30 errors. New errors replace the existing record in chronological order beginning with the oldest error record. The records will be completely lost when the Controller is turned OFF or reset or when it receives a RESET command.

The Controller classifies and keeps the number of each type of error. The Controller also calculates MCBF (mean cycle between failures) simultaneously. The Controller keeps all these data items until the user turns OFF or resets the Controller.

To use this function, connect the C200H-PRO27-E Programming Console (sold separately) to the Controller through the V700-P10 Programming Console Conversion Cable (sold separately). Refer to 6-6-9 Latest Error Data and 6-6-10 Sta- tistic Error Data for details.

Note The record of all errors will be lost when the Controller is turned OFF or reset or

when it receives a RESET command. Do not turn OFF or reset the Controller in order to keep the records.

4-1SectionController

If more than one Controller is connected to a single host through Link Adapters, each Controller needs an ID number so that the host can discriminate each of them. Such an ID number is called node number. Each Controller must have a unique node number.

Each command or response of the Controller includes the node number of the Controller. Communications will not be possible if the node number is wrong. The node number must be correctly set regardless of whether the host is connected to a single or multiple Controllers.

As shown below, SW1 on the left is for 10’s digit and SW2 on the right is for 1’s digit, which can set numbers within a range between 00 and 31.

Pin 1: Communications Format Setting (V700-CD1D-V3/CD2D-V3 Only)

This pin can be used to enable or disable BCC for the command and response format between the host and the Controller . When BCC is enabled, checking for communication errors between the host and Controller, resulting from factors such as noise, is executed using horizontal parity. Control of communications with the host can be simplified by disabling BCC, but communications error checking will not be executed in communications frame units. It is therefore recommended that the parity bit be set to either even or odd.

Pin 1 Description

ON BCC disabled OFF BCC enabled

Note Always set this pin to OFF for the V700-CD1D-V2 or V700-CD2D-V2. They can-

not operate normally with this pin set to ON.

Pins 2, 3, and 4: Communications Sync Setting

If two or more Antennas are used closely together, the Controllers must operate in synchronous operation in order to prevent mutual interference. Therefore, communications sync settings are required in each Controller. Refer to 3-4 Mutual Interference Preventive Function (Synchronous Function) for details.

Note 1. Make sure to set only one of the Controllers as the Master and the other

Controllers as Slaves in synchronous operation, otherwise the RFID System will not operate.

2. Make sure that all Controllers in synchronous operation are the same in mode (i.e., RW sync, RO sync, or no sync), otherwise the Controllers will be affected and will not communicate properly.

Pin 5: Low Power Consumption Setting

In case commands can be issued at the time of communications only, the Antenna power can be shut down to reduce the total power consumption of the RFID System. In energy-saving mode, the power consumption of the RFID System is approximately 30% of that in normal operation.

If the Controller is set to energy-saving mode, the Antenna will have output only at the time of communications. This mode is available after the communications command is issued to select the single trigger, single auto, or multi-trigger option.

Note Do not set the Controller to energy-saving mode if the single repeat, FIFO trig-

ger, FIFO auto, FIFO repeat, multi-trigger, or multi-repeat option is selected, otherwise a command error will result.

Pin 6: Communications Distance

In order to perform long-distance communications, the RFID System automati-

4-1SectionController

cally selects the amplification factor when the Antenna receives signals from the ID Tag.

It may, however, be better not to select the automatic amplification factor if multiple commands are used or if there is excessive noise. If this automatic selection is suppressed, the RFID System cannot communicate with far ID Tags but the RFID can perform stable communications.

The RFID System allows a selection of either the long-distance mode (automatic selection of amplification factor) or stable-communications mode (no change in amplification factor).

Pin 6 Description

ON Stable communications mode OFF Long-distance mode

Note Environmental noise can be easily checked with the Programming Console by

executing the NO I S E CHECK command when the Controller is in long-distance mode. Then if the value of noise reads more than 30, it is recommended that the Controller be used in stable communications mode.

Pin 7 (V700-CD1D-V3): Not used

Do not use this pin. Always set this pin to OFF.

Pin 7 (V700-CD2D-V3): RS-485 Terminating Resistance

When multiple Controllers are connected to a single host, the Controller or host at each end must be connected with terminating resistance to ensure stable operation.

This pin can be used to set the built-in RS-485 terminating resistance to ON or OFF.

Pin 7 Description

ON RS-485 terminating resistance is ON. OFF RS-485 terminating resistance is OFF.

Note Of the Controllers and host connected in series, the terminating resistance must

be set to ON for the device connected at each end. Set the terminating resistance for all others to OFF. If these settings are made incorrectly, operation will be unstable.

Pin 8: Synchronous Terminating Resistance

If two or more Controllers with Antennas are located closely together, the Controllers must be in synchronous operation in order to prevent Antenna mutual interference. In that case, the Controllers must be connected to one another in series through a synchronous cable. The terminating resistance of the Controller at each end must be set to ON for stable communications.

Use this pin to set the terminating resistance to ON or OFF.

The maximum power consumption of the Controller is 20 W (i.e., 0.8 A at 24 VDC). An inrush current, however, will flow when the Controller is turned ON. Take this into consideration when preparing the power supply. A power supply with an output of 1.1 A min. at 24 VDC is recommended.

Note 1. If the Antenna and power supply are too close, some noise generated from

the power supply may interfere the communications of the Antenna. Make sure that there is a distance of 1 m or more between the Antenna and power supply.

2. If the Controller and Antenna are too close, the Controller may interfere with the communications between the Antenna and ID Tag. Make sure that there is a distance of 80 cm or more between the Controller and Antenna.

3. Provide 24 VDC to the Controller. The permissible variation of the power

–15%

supply is between 20.4 and 26.4 VDC (i.e., 24 VDC

). Make sure

+10%

that the supply voltage is within this range.

4. The maximum power consumption of the Controller is 20 W . An inrush current of approximately 30 A at 24 VDC, however, flows when the Controller is turned ON. Take this into consideration when preparing the power supply.

5. Provide a power wire with a thickness of at least AWG18 in order to prevent the dropping of voltage. It is recommended that twisted-pair wire be used for the power line.

6. Ground the Controller at a resistance of less than 100

Ω to protect the Controller from noise interference. The thickness of the ground wire must be at least AWG18. If two or more Controllers are connected to one another in synchronous operation, be sure to ground the Controller located at either end of the system at a resistance of less than 100 Ω and connect the ground terminals of other Controllers with the shielded wire of the synchronous cable. If the Controller is not ground properly, it may not operate.

• Use the provided ferrite core for the suppression of noise generation as shown below.

1, 2, 3... 1. Wire the power supply and ground wires.

2. Wind the power supply and ground wires together around the ferrite core once so that the ferrite core will not move as shown below. The ferrite core must be located within 10 cm of the Controller.

3. Close and press the ferrite core until the ferrite core clicks so that the ferrite core will be locked.

4-2 Installation of Antenna

4-2-1 Installation Environment

Installation Location

Do not install the Antenna in the following locations.

• The ambient temperature is not within a range between –20°C and 55°C or locations with radical temperature changes resulting in condensation.

• The humidity is not within a range between 35% and 80%.

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

• The Antenna will be subjected to direct vibration or shock.

• Water, oil, or chemical will be sprayed onto the Antenna.

Countermeasures Against Noise

The communications range of the Antenna drops due to ambient noise. Refer to 8-2 Communications Distance Characteristics vs. Ambient Noise for details.

The following provides information on countermeasures against ambient noise.

4-2SectionInstallation of Antenna

Power Lines and High-tension Lines

Inverters, Motors, and Other Driving Mechanisms

Displays of Personal Computers and Programmable Terminals

Switching Power Supplies

Do not wire the Antenna cable along with high-tension lines or power lines. Keep the Antenna cable as far away as possible from them.

Be sure to ground the frames of driving mechanisms and keep them as far away as possible from the Antenna.

Keep the displays of personal computers and Programmable Terminals as far away as possible from the Antenna.

Be sure to ground switching power supplies and keep them as far away as possible from the Antenna.

If the Antenna is still influenced by noise in spite of the above countermeasures taken, the communications range must be reduced.

The Controller in stable communications mode rather than long-distance mode withstands more ambient noise although the communications range decreases.

Note Keep the above in mind before installing the Antenna. Before the Antenna is put

in actual use, be sure to conduct enough tests of the Antenna.

5-1 Commands and Responses

In order to communicate with the ID Tag in the communications area of the Antenna, commands must be selected and used according to the mode and movement of the ID Tag.

ID Tags in Communications Area

ID Tags operate in single mode, FIFO read/write mode, or multiple, simultaneous access mode according to the number and provided conditions of ID Tags in the communications area.

5-1SectionCommands and Responses

Single Mode

FIFO Read/Write Mode

In single mode, only a single ID Tag can exist in the communications area. A communications error will result if there are two or more ID Tags in the communications area.

In the FIFO (first-in, first-out) read/write mode, the RD-ID System reads and writes data to and from each ID Tag coming into the communications area one after another. S ince every ID Tag finished with communications is set to access prohibit, communications will be possible if only one ID Tag newly arrives in the communication area of th e A n t e n n a where more than one ID Tag exists. An error, however, results if two or more ID Tags arrive in the communications area simultaneously. When the access-prohibited Tag moves out of the communications area, communications will become possible again.

5-3SectionCommunications Operating Sequence

Multiple, Simultaneous Access Mode

In this mode, communications with all ID Tags in the communications area can be made on receipt of the command.

Note In FIFO read/write mode, make sure that multiple ID Tags do not arrive in the

communications area together , otherwise a communications error will result and further communications will not be possible until there is only a single ID Tag in the communications area.

5-2 Movement of ID Tag and Command

The V700-series RF-ID System (1) receives a command from a connected host, and (2) communicates with an ID Tag according to that command. Then (3) the results are returned to the host as a response.

5-2-1 Operating Status of Controller

Ready to Receive Command

Processing Command (Except POLLING AUTOREAD Command)

In this state, the Controller has no command in process and the Controller is ready to receive any command other than a subcommand. When a command is received, the Controller starts processing the command.

After a command is received by the Controller, the Controller ignores the next command until the Controller processes the command and returns a response. The Controller, however, accepts the STOP or RESET command anytime.

5-3 Communications Operating Sequence

ID Tag

(2)

The sequence for operations such as communicating with ID Tags and the timing for returning responses will vary depending on the instructions in the command. It must be handled according to the status of ID Tags in the Antenna communications area and the form of the connection with the host.

5-3-1 Single Trigger Mode

In this mode, the Controller communicates with the ID Tag in the communications area provided that the ID Tag is not moving. Therefore, it is necessary to check tha t t h e I D Tag is at a standstill in the communications area. If the ID Tag is not in the communications area, an error response is returned.

5-3-3 Single, FIFO, and Multiple Repeat Mode

In single, FIFO, or multiple repeat mode, when the Controller receives a command from the host, it waits for an ID Tag to approach. Whenever an ID Tag passes through the communications area, the Controller communicates with the ID Tag and returns a response to the host. In this mode, the next command other than the STOP or RESET command is not accepted until the operation of the Controller is stopped or reset with the STOP or RESET command. When the

5-3-4 Polling Auto Mode

If a normal AUTO command is used while a single host is controlling more than one Controller, responses will be returned when communication with the ID Tag is completed and thus responses will be returned by multiple Controllers simultaneously. However, if the POLLING AUT O command is sent instead, the Controllers will return responses at the request of the host. In this way, responses will not be sent simultaneously and multiple Controllers can be controlled. While the POLLING AUTO command is executed, no command other than the POLLING subcommand, RESET command, or STOP command can be executed.

In the following example, the POLLING AUTO command is executed to two Controllers.

5. The host can use subcommands to check the process of command execution or cancel the execution of the POLLING AUTO processing. If the ID Tag has not approached yet, a response indicating the status is sent in reply to an inquiring subcommand.

6. When the ID Tag passes through the communications area of node 1’s Antenna, communication is established.

7. If a subcommand is sent for confirmation to the Controller that has finished processing communications with the ID Tag, the Controller will return a response of a process result.

5-3-5 Multi-trigger and Multi-repeat Modes

Data is exchanged with all ID Tags in the communications area. There are two modes used: multi-trigger and multi-repeat. In multi-trigger mode, data is exchanged with all ID Tags in the communications area when a command is received, and a communication completed response is returned when the processing ends. In multi-repeat mode, ID Tags are awaited from the point when a command is received, and communications continue with all ID Tags approaching the communications area. Processing is stopped by a STOP command.

2. The Controller communicates with ID Tags in the communications area and saves a maximum of 16 simple numbers (0 to F) in its internal memory. At the same time, the Controller includes those simple numbers in its response to the host. When the Controller has completed communicating with all ID Tags in the communications area, it sends a detection completed response to the host.

3. The host attaches a SPECIFY TAG command to the simple number of any ID Tag with which it wants to communicate, and then it sends it to the Controller.

4. The Controller executes the SPECIFY TAG command for the ID Tag corresponding to the simple number.

5. When the processing has been fully completed, the host sends a STOP command to the Controller. After the Controller receives the STOP command, it clears from its memory the simple numbers that it had saved. (The numbers are not cleared until the STOP command is executed.)

Note When using the selective access mode, set the Controller to energy-saving

mode.

Precautions when Using Selective Access Mode

1, 2, 3... 1. When using the selective access function, set pin 5 of the Controller’s switch

3 to ON and set the Controller to energy-saving mode. A command error will occur if selective access is used while in the normal oscillation mode.

2. If an ID Tag with the simple number specified by the SPECIFY TAG command does not exist in the communications area, the Controller returns a no Tag error to the host.

memory for 16 of them and not for the others. The Controller, however, returns a response to the host for all of the ID Tags, with “X” indicated instead of the simple number for all of the ID T ags exceeding 16. If X is specified in a SPECIFY TAG command, the Controller returns a command error to the host.

5. Once the Controller has saved a simple number to memory, that number is not cleared until a STOP command is executed. Until a STOP command is executed, no commands other than selective access commands are accepted (with the exception of RESET (XZ) commands). If the DETECT TAG command is executed again with no new ID Tag entering the communications area, the Controller returns only a detection completed response to the host.

6. If a new ID T ag enters the communications area after a DETECT T AG command has been executed, then, when the DETECT TAG command is next executed, data is exchanged with only that new ID Tag, and the Controller saves the simple number to memory. (If there are already 16 simple numbers saved in the Controller memory, the new ID Tag is handled as described in (4) above.)

5-6 List of Options

The following eight options can be placed in the READ, WRITE, ADD, and SUBTRACT command frame structure to specify communications according to the number of ID Tags in the communications area, their conditions, the movement of the ID Tags, and the operating status of the Controller.

Symbol Name Description

ST Single Trigger Immediately after receiving a command, the Controller communicates with the Tag and

sends a response. After sending a response, the Controller is set to a standby state and waits for a new command. There should be only one Tag within the communications area of the Antenna.

SA Single Auto After receiving a command, the Controller waits for an approaching Tag, communicates with

the Tag, and sends a response. After sending a response, the Controller is set to a standby state and waits for a new command. There should be only one Tag within the communications area of the Antenna.

SR Single Repeat The Controller waits for an approaching Tag, communicates with the Tag, and sends a

response. After sending a response, the Controller is set to a standby state and waits for approaching Tags. The Controller repeats this process until it receives a STOP or RESET command. There should be only one Tag within the communications area of the Antenna.

FT FIFO Trigger Immediately after receiving a command, the Controller communicates with the Tag and

sends a response. After completing communications, the Controller disables Tag operation and is set to a standby state and waits for a command after sending a response. There should be only one operable Tag within the communications area of the Antenna.

FA FIFO Auto After receiving a command, the Controller waits for an approaching Tag, communicates with

the Tag, and sends a response. After completing communications, the Controller disables Tag operation and is set to a standby state awaiting approaching Tags after sending a response. There should be only one operable Tag within the communications area of the Antenna.

FR FIFO Repeat The Controller waits for an approaching Tag, communicates with the Tag, and sends a

response. After completing communications, the Controller disables Tag operation and is set to a standby state and waits for approaching Tags after sending a response. The Controller repeats this process until it receives a STOP or RESET command. There should be only one operable Tag within the communications area of the Antenna.

MT Multi-trigger Immediately after receiving a command, the Controller communicates with all the Tags

within the communications area of the Antenna and sends a response. After completing communications, the Controller disables Tag operation. After sending a response, the Controller is set to a standby state and waits for a new command.

MR Multi-repeat The Controller waits for approaching Tags, communicates with all the Tags within the

communications area of the Antenna, and sends a response. After completing communications, the Controller is set to a standby state and waits for approaching Tags.

The Controller repeats this processing until it receives a STOP or RESET command. Lj (j: *,

0 to F)

Selective access

The Controller communicates with specified Tags only from among multiple Tags in the

communications area.

5-7SectionData Code Designation

Note Set the Controller to normal mode if the single repeat, FIFO trigger, FIFO auto,

FIFO repeat, or multi-repeat options are used. A command error will occur if the energy-saving mode is used in these cases. Set the Controller to energy-saving mode, however, when the selective access mode is used.

5-7 Data Code Designation

Specify in the command whether read or write data is handled as ASCII text data or handled as hexadecimal numeric data.

5-7-1 ASCII Code Designation: A

A byte of ID Tag data is sent directly as ASCII code or as JIS8 code. A single character sent corresponds to one byte of data in the ID Tag. Character data can be written or read directly. Do not use the CR control code with data that is sent. A command error will occur if CR is specified for write data.

5-8 Explanation of Commands and Responses

The transmission of a command from the host to the Controller or the transmission of a response from the Controller to the host varies with the type of command and the difference in communications designation.

5-9SectionACK/NACK Control

No Response

When the Controller receives the RESET command, the Controller is reset without returning a response and waits for the next command.

One to One

If the single trigger, single auto, FIFO trigger, or FIFO auto option is specified for communications with the ID Tag or a command not for communications with the ID Tag is specified, a single response will be returned for a single command.

Multiple Responses

If the single repeat, FIFO repeat, multi-trigger, or multi-repeat option is specified for communications with the ID Tag, multiple responses will be returned for a single command.

Host

Controller

5-9 ACK/NACK Control

After the Controller receives a command from the host and returns a response, if the host cannot receive the response normally, the host must send the same command to the Controller again for execution. This is possible only if the ID Tag is at a standstill in the communications area of the Antenna or moving slow enough so t h a t t h e I D Tag can receive the command within the communications area. The system in ACK/NACK control can receive the response without sending the command to the ID Tag.

Use of ACK/NACK Control

The Controller returns a response for a command sent from the host and the host sends ACK when the response to the command is received. Then the Controller determines that the host has received the response normally and waits for the next command. If the Controller does not receive ACK within a preset timeout period or the Controller receives NACK, the Retry Flag is set and the response is returned to the Controller again. This is repeated at least nine times.

5-10-5POLLING AUTOREAD: PR

When the host sends POLLING AUTOREAD command to the Controller, the Controller immediately returns a response to the host indicating the acceptance of the command. Then the Controller waits for the approaching ID T ag and reads the data of the ID T ag when the ID Tag is in the communications area of the Antenna. When the Tag is in the communications area, the host can use a POLLING subcommand to check the results of the processing of the command.

Memory Check Function

By executing the MEMORY CHECK and MEMORY CALCULATE commands, it is possible to check for the accidental overwriting or destruction of memory . The CRC (cyclic redundancy check) code is written or checked with the check block specified by the user. The CRC code is calculated by the generating polynomial

+ X12 + X5 + 1.

• The calculation area is the portion of the check block specified by the first address and the number of bytes excluding the last two bytes. The check code area is the last two-byte portion. If a command to write a check code is sent, the CRC code of the data in the calculation area is calculated and compared with the data in the check code area. If they coincide, response code 75, which indicate normal data transmission, is returned, otherwise response code 76 is returned as a warning.

Protect Data

The protect data item on each page is expressed by single-bit data. Protect data items are arranged in decreasing numerical order beginning with those on page

30. There are protect data items on two zero-fixed pages after the protect data item on page 1.

Three 32-bit data items are considered to be binary data, the hexadecimal conversion of which is used as protect data.

The V700-D23Pjj, however, uses the data items on page 1 through 14 only. The data on any other page can be set or released, which has, however, nothing to do with the operation of the V700-D23Pjj.
