3-1 Outline of Operations

The RFID Unit reads or writes to the tags using commands sent from the host

control unit, and returns the processing responses to the host control unit.

The RFID Unit has three operating modes. The conditions for changing the

mode are shown in the following diagram.

(1) Command waiting mode

In this mode, the COM port is open and ready to receive a command as a

virtual COM port.

(2) Oscillation mode This mode performs communications with the tags.

When using FIFO access mode, oscillation mode continues until a STOP

command or STOP signal is input.

(3) Standby mode In this mode, the COM port is closed as a virtual COM port.

Note As the first step, open the COM port so that the RFID unit will shift its mode from “Standby

mode” to the “Command waiting mode”.

3-2-1-1 I-CODE1 Chip (Philips IC product name : SL1 ICS30 01, SL ICS31 01)

1) Memory Map of I-CODE1

These specifications describe a Tag incorporating an IC chip I- CODE1 Label

IC from Philips, which is accessed by the system.

This chip consists of a 64-byte memory. The upper five blocks (Blocks 0 to 4)

of the memory are used as a system area having functions that do not relate to

user memory. OMRON offers special commands for accessing this area in

order to ensure the great ease of these functions by the user.

Refer to Command List for details. OMRON defines the blocks below Block 5

as the user memory area. Block 5 is page 00h, and the subsequent blocks are

allocated as shown below.

The memory is organized with four bytes as one page (4 bytes = 32 bits).

One page is the minimum unit that can be read from and written to the

memory.

The memory allocation described in this user's manual is in accordance with

OMRON's memory allocation scheme.

3-2 Tag Access Functions

Section 3-2

3-8

3-2-2 Single Access and FIFO Access Functions

Single Access Mode Use this mode to communicate with only one tag within the RFID Unit

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 RFID Unit

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.

3-2 Tag Access Functions

Section 3-2

3-9

3-2-3 Lock Function

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.

Caution

The method for controlling the RFID Unit from the host control unit is the CR 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.

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

Section 4-1

4-1 Communications Frames

4-1-1 CR control

The frame format consists of data in ASCII characters and a terminator. '<CR>' (ASCII: 0D Hex), the

terminator, cannot be used in the data ASCII characters.

The CR control method is useful when the RFID Unit is connected to a PC and the like.

Data 1 Data 2 ⋅⋅⋅⋅⋅⋅ Data n Terminator

Data No. of

characters Details

Data 1 to 138 Command parameters (ASCII characters)

Terminator 1 Code ‘<CR>‘ (0D Hex), which indicates end of communications

frame

(Communications Control Procedure)

When a character is first received, reception starts, and when <CR> is received, the frame ends. If the

interval between data is greater than 2 sec, a communications error occurs. If a communications error

occurs, a frame error end code (Error code: '18') is sent as the response from the RFID Unit to the host.

3) 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 RFID Unit continues unmodulated oscillation. Tags with

which communications have been completed do not respond to the next com-

mand. 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 RFID Unit 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 RFID Unit 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 01, 31, 35, 3A, 41, and 42.

5-3-2 TAT (Turn Around Time)

The TAT is the time taken from when the host control unit sends a command to the RFID Unit, 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-CODE1 I-CODESLI

(1)During command send

9[char.] × 11 [bits] / 9600[bps] × 1000[ms/s] ≈ 10.32ms

(2)During communications

6.5 + 6.2 = 12.7ms

(3)During reception of response

43[char.] × 11 [bits] / 9600[bps] × 1000[ms/s] ≈ 49.27ms

The TAT in to the above example is (1) + (2) + (3) = 72.29

ms.

(1)During command send

11[char.] × 11 [bits] / 9600[bps] × 1000[ms/s] ≈ 12.61ms

(2)During communications

6.5 + 6.0 = 12.5ms

(3)During reception of response

43[char.] × 11 [bits] / 9600[bps] × 1000[ms/s] ≈ 49.27ms

The TAT in to the above example is (1) + (2) + (3) = 74.38

ms.

The calculations are performed according to the following conditions.

•

Communications mode : Single Trigger Mode

•

Communications control method : CR control

•

Baud rate : 9,600 bps

•

Data code specification : Hexadecimal

•

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