3-2 Tag Access Functions

Section 3-2

3-6

3-2-2 Single Access and FIFO Access Functions

Single Access Mode

Use this mode to communicate with only one tag within the R/W Module

communications area.

The time required for communications with the tag is shorter compared with

FIFO access mode.

FIFO Access Mode

FIFO (First In First Out) access mode enables reading tags in order as they

enter the antenna communications range. Tags with which communications

have been completed are prohibited from being accessed again, so even if

tags with which communications have been completed are still within range of

the antenna, communications will be possible with new tags as they enter the

communications range. When two or more tags enter the antenna

communications range at the same time, a communications error will occur.

When a tag to which access has been prohibited moves out of the

communications area, communications with it will be possible again if it

reenters the antenna communications range.

The above diagram shows an example of a tag inspection line.

When the distance between tags is small, two tags may enter the R/W Module

communications range at the same time. If this happens when in Single

Access Mode, a communications error will occur, or even if read/write appears

to have been performed, there is no way to know which of the two tags was

read. In FIFO Access Mode, tags entering communications range can be read

or written to in order, so this mode is suited to applications such as a tag

inspection line, in which the order of access is important.

The lock function is a protection function provided to prevent the loss of data

by unintentionally overwriting fixed data stored on the tags. This function can

be set using the lock command. This function can be set using the lock

command.

There is a lock setting area in the tag system area, enabling user-defined

areas to be write-protected one page at a time. If the write command is

executed for a page that has been write-protected, a write processing error will

occur.

Note The lock function used with the V720 Series cannot be canceled. Pages that have been

write-protected cannot be written to again, so be careful when using this function.

3-3 Tag Access Functions

Section 3-2

3-8

3-2-4 Tag Identification Access Function

Only when the ID code stored on the tag and the ID code included in the

command sent from the antenna match will the tag respond. This is called the

tag identification access function.

Commands sent from the R/W Module respond without depending upon the ID

code stored in the tags.

Reference Information for I-CODE SLI

Followings are examples of tag identification access function using OMRON’s antenna and reader

such as V720-H04 and V720S-BC5D4A.

(1) The set values of the tag ID codes are given in the following table. These settings can be made by

using the R/W Module or the reader.

Tag No.1 Tag No.2 Tag No.3

AFI 11 Hex 22 Hex 33 Hex

(2) Tag ID Access Operation

•Not Using Tag ID Access

(1) The reader’s AFI set value is taken to be 00 Hex. (Set at

the factory.)

(2) Multiple tag access commands are executed.

(3) All tags within communications range respond.

(The tag family codes and application IDs are not

required.)

•Using Tag ID Access

(1) The set value of the reader’s AFI is 22 Hex.

(2) Multiple tag access commands are executed.

(3) Only tags with the same ID code set in (1) and which are

within communications range respond. In this example,

only tag No. 2 responds.

Caution:

There are two methods to control an R/W module from the host control unit; the CR control and

number-of-characters control.

OMRON’s existing product (V720S-HMC73/HMC73T) allows user to use either methods but this

product (V720S-HMC75) introduces only the number-of-characters control method.

CR control

Data in the communications frame is handled as ASCII characters in

2-digit hexadecimal code (ASCII code). CR control simplifies operations

with the host.

Number-of-characters

Control

Data in the communications frame is handled as hexadecimal code,

thus minimizing communications time with the host.

In this manual, the codes are displayed as follows:

ASCII characters: ’ ×× ‘

Control code using ASCII characters: ‘<Control code>‘

Displayed as hexadecimal code: ×× Hex

4-1 Communications Frames

4-2

4-1 Communications Frames

4-1-1 Number-of-characters Control

The frame format is given below, with ‘<STX>‘ (ASCII code: 02 Hex) as the beginning of the frame.

The number-of-characters control method is useful when the R/W Module is directly connected to a

microcomputer board, allowing communications time with the host device to be reduced.

(Communications Control Procedure)

When character data has been received for the number of characters given at the beginning of the

frame, the frame is assumed to have ended. If the interval between data is greater than 2 sec,

processing of the reception is interrupted, and the sleep mode is engaged. If reception is stopped,

responses are not returned from the R/W Module to the host.

Data: 69 characters max

1) Specifying the Communications Mode

The following seven communications modes are supported for different processing procedures and

execution timing.

Communica-

tions mode No. Details

Single Trigger 0 Hex

After a command is received, communications with the tag is performed immediately

and a response is sent. If there is no tag in communications range, a No Tag error is

sent. After the response has been sent, the mode changes to sleep mode.

Only one tag is permitted in communications range.

Single Auto 1 Hex

After a command is received, this mode waits for a tag to enter communications

range, and then performs communications with the tag. After the response has

been sent, the mode changes to sleep mode. If a STOP command is received

while waiting for a tag, the command is ended.

Only one tag is permitted in communications range.

Single Repeat 2 Hex

After a command is received, this mode waits for a tag to enter communications

range, and then performs communications with the tag. If this mode has been

specified, the command is repeated sequentially until a STOP command is re-

ceived. This mode is enabled only for read commands.

Only one tag is permitted in communications range.

FIFO Trigger 8 Hex

After a command is received, communications with the tag is performed imme-

diately and a response is sent. If there is no tag in communications range, a No

Tag error is sent. Access is prohibited to tags with which communications have

been completed, and the R/W Module continues unmodulated oscillation. Tags

with which communications have been completed do not respond to the next

command. After the response has been sent, the mode changes to sleep mode. If

a STOP command is received, oscillation stops.

FIFO Auto 9 Hex

After a command is received, this mode waits for a tag to enter communications range,

and then performs communications with the tag. Access is prohibited to tags with which

communications have been completed, and the R/W Module continues unmodulated

oscillation. Tags with which communications have been completed do not respond to

the next command. After the response has been sent, the mode changes to sleep

mode. If a STOP command is received while waiting for a tag, the command is ended.

FIFO Continu-

ous A Hex

After a command is received, this mode waits for a tag to enter communications range,

and then performs communications with the tag. Access is prohibited to tags with which

communications have been completed, and the R/W Module continues unmodulated

oscillation. Tags with which communications have been completed do not respond to

the next command. After the response has been sent, when ACK is received, this mode

again waits for a tag to enter communications range, and then performs communica-

tions with the tag. If a STOP command is received while waiting for a tag, the command

is ended.

FIFO Repeat B Hex

After a command is received, this mode waits for a tag to enter communications range,

and then performs communications with the tag. Access is prohibited to tags with which

communications have been completed. Tags with which communications have been

completed do not respond to the next command. If this mode has been specified, the

command is repeated sequentially until a STOP command is received.

Note Single repeat mode can only be specified for commands 31, 35, 3A, 41, and 42.

Example: Reading data from pages C, 5, and 9

T = 1.3 × (12-5+1) + 6.0 = 16.6ms

Example: Writing data to pages 2, 4, 9, and 10

T = 12.3 × 4 + 1.3 × ( 10 - 2 + 1 ) + 15.5 = 76.4ms

Communications Time Calculation Conditions

•

Communications mode: Single Trigger Mode

•

Communications errors must not occur, such as due to noises.

5-3 Communications Time (Reference)

Section 5-3

5-3-2 TAT (Turn Around Time)

The TAT is the time taken from when the host control unit sends a command to the R/W Module, to

when a response is received and completed.

The time differs depending on the baud rate and the communications control method setting.

Example of TAT Calculation

Example: Reading from page 0 to page 4

I-CODE SLI

(1)During command send

8 [byte] × 10 [bits] / 9600 [bps] × 1000 [ms/s] ≈ 8.33ms

(2)During communications

6.5 + 6.0 = 12.5ms

(3)During reception of response

24 [byte] × 10 [bits] / 9600 [bps] × 1000 [ms/s] = 25ms

The TAT in to the above example is (1) + (2) + (3) = 45.83 ms.

The calculations are performed according to the following conditions.

•

Communications mode : Single Trigger Mode

•

Baud rate : 9,600 bps

•

Commands sent from the host control unit are sent continuously without spaces between the

characters.

•

Communications errors must not occur, such as due to noises.
