System Description Section 1-1

Section Overview This manual covers the operation of two ID Sensor models, the C200H-

IDS01-V1 Electromagnetic Induction ID Sensor Unit and the C200H-IDS21
Microwave ID Sensor Unit. The main difference between the Units is the dis­tance at which the ID Sensor can read data from or write data to the Data Car­rier. The Microwave ID Sensor Unit allows the Data Carrier to be placed
farther from the Unit.

This section describes the components, installation, and configuration of both
models.

1-1 System Description

The ID Sensor system is a versatile noncontact identification system compris­ing an ID Sensor Unit, a single Read/Write (R/W) Head or Antenna, and a
Data Carrier.

The ID Sensor mounts to a C200H Programmable Controller (PC); the Data
Carrier mounts to a moving workpiece or workpiece carrier. The R/W Head or
Antenna, connected to the ID Sensor Unit by a cable, must be positioned
within communication range of the travel path of the Data Carrier. Responding
to commands from the user program in the CPU of the PC, the ID Sensor
reads data from or writes data to the Data Carrier through the R/W Head or
Antenna. The operation of the ID Sensor can be monitored and tested with
the Handheld Programming Console; messages appear on the display of the
Console.

The following diagram illustrates two ID Sensor systems, one using a C200H­IDS01-V1 ID Sensor and one using a C200H-IDS21 ID Sensor.

Data is transferred between the ID Sensor Unit and the Data Carrier with the
following six dedicated commands:

Read
Write
Auto Read
Auto Write
Clear-all
Auto Read/Write Abort
Data management (C200H-IDS01-V1 only)

Up to 1024 bytes of data can be read from or written to the Data Carrier at
one time. Clear-all clears all data in the Data Carrier’s memory (2K bytes).
These commands are compatible with the V600 and V620 ID Controllers.

Monitoring with the
Handheld Programming
Console

The Handheld Programming Console can be used for monitoring data transfer
as well as errors that have occurred during operation. A keyboard sheet for
the Handheld Programming Console is included with the ID Sensor Unit.

Storage of Error
Information

Error information is stored in the internal memory of the ID Sensor Unit. A
built-in capacitor stores the information for 15 days (at 25

°C).

Compatibility The following table lists the compatibility between the I/D Sensor Unit and the

R/W Head, R/W Antenna, or Data Carrier.

Note Refer to the list of applicable manuals in the About this Manual section.

Differences between
C200H-IDS01 and
C200H-IDS01-V1

The C200H-IDS01-V1, which is an updated version of the C200H-IDS01, has
the following three new features in addition to all the capabilities that the
C200H-IDS01 possesses. The C200H-IDS01 is compatible with the C200H­IDS01-V1.

1,2,3... 1. Connecting to Data Carrier Incorporating EEPROM

The C200H-IDS01-V1 reads data from and writes data to the V600-D@@P@@
containing an EEPROM. To read data, the user can select the communica­tions distance priority mode or communications speed priority mode with the

Features Section 1-2

2. New Commands
The C200H-IDS01-V1 incorporates data management commands, with which

it is possible to check the reliability of the Data Carrier’s data. The details of
the commands are as follows:

3. Hexadecimal Page Number Display
The page number is displayed in hexadecimal, in which case the rightmost

two digits of the address are displayed as the page number.
In the following example, the user has access to address 0A00 or 1000.

Function Command Meaning

Checking of data MD-K By adding a check code to the Data Carrier’s data, it is possible to detect a data

error due to the battery of the Data Carrier that incorporates SRAM, or
excessive overwriting operations of the Data Carrier that incorporates
EEPROM. Use the MD-K command to calculate and write the check code to the
Data Carrier. Use the MD-C command to collate the check code. The MD-K
command and MD-C command must be always used together.

MD-C

Checking of the number
of overwriting operations

MD-L Check the life of the Data Carrier’s EEPROM by counting the number of

overwriting operations. The Data Carrier’s EEPROM allows a total of 100,000
overwriting operations.

MD-S Use this command to specify the number of overwriting operations in the life of

the EEPROM in advance. Every time a write operation is performed, 1 is
subtracted and the Data Carrier will detect when the life has expired. This com­mand is only available with models of lot number @@55 (May 1995) or later.

communications speed priority mode with pin 2 of the DIP switch
when the C200H-IDS01-V1 accesses the EEPROM Data Carrier.
Neither of these modes are, however, available when the ID Sensor
Unit accesses the SRAM Data Carrier or when the C200H-IDS21 ac­cesses any Data Carrier, in which case turn pin 2 OFF. Refer to the

V600 FA ID System R/W Heads and EEPROM Data Carriers Oper­ation Manual for the communications distance and speed of the EE-

PROM Data Carrier.

1-4 System Configuration

The diagrams below illustrate the system configurations of the C200H-IDS01­V1 Electromagnetic Induction ID Sensor Unit and the C200H-IDS21 Micro­wave ID Sensor Unit.

The ID Sensor Unit transfers data through the Read/Write Head (or Antenna)
to a Data Carrier, which is mounted on a moving workpiece. The ID Sensor
Unit transfers the desired data according to instructions from the user pro­gram in the CPU (refer to 2-3 The User Program). Only one Read/Write Head
(or Antenna) can be connected to the ID Sensor Unit.

Data and error information can be monitored through a Handheld Program­ming Console connected to the ID Sensor Unit. The data is displayed on the
screen of the Programming Console.

Mounting the ID Sensor
Unit

As a Special I/O Unit, an ID Sensor Unit can be mounted to any slot on the
C200H PC Backplane except the two rightmost slots; these two slots are
reserved for peripheral devices.

Up to ten Special I/O Units can be mounted to a PC system. (The PC Link
Unit, used to link two PCs, is a Special I/O Unit.) The number of ID Sensor
Units which can be connected may be limited by the size of the Backplane,
the Power Supply, and the current consumption of each Unit. For details, refer
to the C200H Programmable Controller Installation Guide.

Mounting to a Remote I/O
Slave Rack

The maximum number of Special I/O Units that can be mounted to a Remote
Slave Rack differs depending on the group (A, B, C, or D, as shown in the fol­lowing table) to which they belong.

The information in this table applies only when no other Special I/O Units are
mounted to other Racks (PC or Expansion I/O Racks) and the Units in this
table are mounted only to a Remote I/O Slave Rack.

When combining Units from groups A, B, C, and D, use the following formulae:
3A + B + 2C + 6D

≤ 12

A + B + C + D

≤ 8

A maximum of ten Units can be mounted to one Remote I/O Slave Rack.
However, when mounting ten Units, the NC211 Position Control Unit is
counted as two Units and, if a PC Link Unit is used, it is counted as one Unit.

Connecting the ID System Refer to page 2 for an illustration of system connections.

Before connecting and wiring the ID Sensor Unit, turn OFF the power to the
PC.

Connect the R/W Head or Antenna to the ID Sensor Unit connector marked
“HEAD” or “Antenna”. (To disconnect the cable, pull while grasping the outer
ring of the cable; do not pull at an angle.)

Section Overview This section contains information on switch settings, bit allocation, and setup

of both ID Sensor systems, as well as explanations of the user program, com­munication commands, and the write-protect function.

2-1 Switch Settings

Unit Number Switch Before beginning operation, use the unit number switch on the front panel to

set the unit number (0 through 9) of the ID Sensor Unit. Each Special I/O Unit
must be assigned its own number; if the same number is assigned to more
than one Unit, an I/O Unit Over error will occur, preventing system operation.

To set the unit number:

1,2,3... 1. Determine the appropriate unit number (refer to 1-5 System Connections

for information on Special I/O Units).

2. Turn OFF the power to the PC.

3. Using a small standard screwdriver, turn the dial to the desired number.
The dial clicks into position at each number setting; do not leave the dial
between settings.

Back Panel DIP Switch (Refer to the diagram of the back panel on page 5.) Pin 1 is used to select the

language of the Programming Console display; leave this pin at the ON (left)
position for English message display. Pins 2 through 4 are for reserved for
expansion; leave these pins at the OFF (right) position.

2-2 Word Settings

Words 100 through 199 in the IR area of the PC are reserved for Special I/O
Units. Each Special I/O Unit is assigned ten words, of which five are needed.
These five words, used by the ID Sensor or other Special I/O Units for data
communication, are referred to as I/O refresh data (stored in the I/O refresh
data area). The five words that are not used can be used as work bits.

Note Each Unit must be assigned a different unit number. If two or more Special I/O

Units are assigned the same unit number, the system is unable to determine
which Unit is to be accessed and an I/O Unit Over error occurs, halting the
system.

Read/Write Bit Areas The following table shows the memory areas (bits) that the ID Sensor Unit

uses when reading data from or writing data to the Data Carrier.

If, during execution of Read or Auto Read, the data read from the Data Carrier
exceeds the capacity of the receiving area, a Read Format error occurs and
word n+4, bit 08 turns ON.

Example:

Data Carrier Read data: 40 bytes = 20 words
Beginning word number (receiving data): DM 1990

As the above table shows, the words specified in the DM area are DM 0000
through DM 1999. If the beginning word number is DM 1990, only 10 words
(DM 1990 through 1999) are available for receiving data. In this example, the
quantity of data to be read is too large for the available space in the DM area.
A Read Format error will occur and the data will not be written to the DM area.

To correct the error, change the beginning word number (receiving data) to a
word number less than DM 1980, or reduce the quantity of data in the Data
Carrier to fewer than 10 words.

Error Storage Area The error information storage area of the ID Sensor Unit is undefined at ship-

ment. Before using the ID Sensor Unit, clear the newest error information and
statistical error information. (Refer to 3-2-9 Error Log Display (ERR) for
details).

Error Messages and Reset
Flags

The ID Sensor Unit’s error messages and reset flags are located in the AR
area as “Special I/O Unit Error Message” and “Special I/O Unit Reset Flag”.
Refer to the C200H Programmable Controller Operation Manual for details.

When the error message flag for a particular unit number is ON, the RUN LED
of the corresponding Special I/O Unit turns OFF.

The User Program Section 2-3

2-3 The User Program

The ID Sensor Unit will not function unless the PC is programmed to control
the operation of the Unit. The Unit communicates with the Data Carrier
through the Read/Write Head by means of the commands provided by the
user program of the PC.

Program examples with detailed explanations are provided in Section 3-1
Program Examples.

The following figure shows the basic operation outline of the program.

Operation Outline

Effect of CPU Status on ID
Sensor Unit

The ID Sensor Unit is controlled by the program contained in the CPU; if an
error occurs in the CPU, an error will also occur in the ID Sensor Unit.

The ID Sensor Unit will continue to execute commands when the PC is in
PROGRAM mode.

The User Program Section 2-3

Writing Data to the Data
Carrier from the CPU

The CPU, via the Write, Auto Write, and Clear-all commands, directs the ID
Sensor Unit to write data to the Data Carrier. The following diagram shows
how the program writes data to the Data Carrier.

1. The CPU sends the command data (the number of words in the com­mand to be sent, the beginning word number of the command, and
the command execution start) to the ID Sensor Unit by using MOV or
OUT.

2. The ID Sensor Unit analyzes the command received from the CPU.

3a. If the command is legal, the ID Sensor Unit writes the required data to

the Data Carrier.

3b. If the command is illegal, the ID Sensor Unit sets the Command Error

flag (word n+4 bit 09) to ON and returns the data to the CPU. At this
time, the ID Busy flag (word n+4 bit 00) is turned OFF.

4. When the ID Sensor Unit has completed communication with the
Data Carrier, the Unit turns OFF the ID Busy flag as the command is
completed, and returns the data to the CPU.

If communication with the Data Carrier fails, or if an error occurs during com­munication, the ID Sensor Unit stops data communication with the Data Car­rier, turns ON the Data Carrier communication error flags, returns the data to
the PC, and turns OFF the ID Busy flag.

Steps 1 to 4 compose one write operation.

Reading Data from the
Data Carrier to the CPU

The CPU, via the Read and Auto Read commands, directs the ID Sensor Unit
to read data from the Data Carrier to the CPU. The following diagram shows
how the program reads data from the Data Carrier.

1. The CPU sends command data (the number of words in the com­mand, the beginning word number of the command, and the begin­ning word number of the data to be received) to the ID Sensor Unit by
using MOV or OUT.

2. The ID Sensor Unit analyzes the command received from the CPU.

3a. If the command is legal, the ID Sensor Unit reads the required data to

the Data Carrier.

3b. If the command is illegal, or the Read format is illegal, the ID Sensor

Unit turns ON both the Command Error flag (word n+4 bit 09) and the
Read Format Error flag (word n+4 bit 08), and returns the data to the
PC. At this time, the ID Busy flag (word n+4 bit 00) is turned OFF.

4. When the ID Sensor Unit has completed communication with the
Data Carrier (step 4), the ID Sensor Unit forwards the read data to the
CPU; the Unit turns OFF the ID Busy flag as the command is com­pleted.

If communication with the Data Carrier fails, or if an error occurs during com­munication, the ID Sensor Unit stops data communication with the Data Car­rier, turns ON the Data Carrier communication error flags, returns the data to
the CPU, and turns OFF the ID Busy flag.

Steps 1 to 4 compose one read operation.

2-3-1 Communication Commands

The ID Sensor Unit is provided with seven dedicated commands for communi­cating with the Data Carrier through the Read/Write Head. The following table
outlines these commands.

Note The Clearall command clears the Data Carrier’s internal memory, regardless

of write protection.

When transferring data between the Data Carrier and the ID Sensor Unit, up
to 1024 bytes (512 words) of data per scan can be written to or read from the
Data Carrier. However, when transferring data between the PC and the ID
Sensor Unit, only 20 words can be transferred per scan. Data is transferred
between the PC and the ID Sensor Unit at a rate of 0.2 ms per word.

If data is to be read and written simultaneously, the read data can be up to 20
words (40 bytes) in length and the write data can be up to 16 words (32 bytes)
in length. (Because the write data is transferred with the command data,
which requires 4 of the 20 words, only 16 words are available to carry the
write data.) If the data exceeds 20 words, more than one scan is required to
transfer the data between the CPU and the ID Sensor Unit, making simulta­neous processing impossible.

For details refer to 3-3 Timing Considerations.

Auto Read/Write Abort This command aborts Auto Read and Auto Write. When this command is exe-

cuted, the ID Sensor Unit is initialized and waits for the next command.

If, after initialization, the ID Sensor Unit receives Auto Read/ Write Abort from
the CPU, the Unit recognizes it as an undefined command and waits for fur­ther command input from the CPU. While the Unit is waiting for a command,
Waiting for Data Carrier (word n+4 bit 01) is ON.

Data Management
(IDS01-V1 Only)

Data Check By adding a check code to the Data Carrier data, it is possible to detect a data

error due to the battery of the SRAM Data Carrier or excessive overwriting
operations of the EEPROM Data Carrier. Use the MD-K command to calcu­late and write the check code to the Data Carrier. Use the MD-C command to
collate the check code.

Usage After data is written to the Data Carrier, use the MD-K command to calculate

and add the check code to the data. To check whether or not the Data Car­rier’s data is corrupted, use the MD-C command before reading the data and
collate the check code.

Command It is possible to calculate, write, or collate the CRC code (see note) in the

check area designated by the command. The CRC code is calculated by
using the generating function X

16

+ X12 + X5 + 1.

Note CRC stands for cyclic redundancy check. The cyclic redundancy

check is an error detection method.

Management of
Overwriting Operations 1

By counting the number of writing operations, it is possible to detect if the
EEPROM DC has been overwritten for 100,000 times.

Usage After writing data to the most frequently used address, renew the number of

overwriting operations in order to check the life of the EEPROM. It is possible
to overwrite data to each address for 100,000 times. Therefore, it is necessary
to count the number of overwriting operations of the most frequently used
address. It is also possible to check the life of the EEPROM without renewing
the number of overwriting operations.

are reserved for the system and the user cannot use these addresses.

Write Protection Example (DC with 254-byte Memory)

1,2,3... 1. In the following example, addresses 0001 to 0012 are write-protected.

2. If the end address is 00, all areas except address 0000 will be write-pro-

tected. In the following example, the end address is set to 00.

How to Cancel Write
Protection

To cancel write protection, set the leftmost bit of address 0000 to 0. When
write protection is cancelled, the data in address 0000 will be null and void.

Note a) Address 0000 is never write-protected.

b) Write protection is effective from address 0001 through the suc-

ceeding addresses. This means that the user must write any data

2-3-5 The Data Carrier’s Production Date

The Data Carrier’s production date is registered in the first 2 bytes (addresses
0000 and 0001) of the Data Carrier’s internal memory before shipment from
the factory. No data can be written to these two bytes; an attempt to do so will
result in a write protect error.

The life of the Data Carrier is approximately 8 years. Develop a program that
monitors the Data Carrier’s production date and reminds the user to replace it
before it becomes unusable.

With the user program in the CPU or a Host Computer, execute Read in order
to read the date of production and monitor the life of the Data Carrier.

2-3-6 Detection of Data Carrier’s Life

The detecting method of the Data Carrier’s life varies with the kind of memory
(SRAM or EEPROM) incorporated by the Data Carrier. In the case of the Data
Carrier with SRAM, the life of the built-in battery will be checked. In the case
of the Data Carrier with EEPROM, the number of overwriting operations (pos­sible up to 100,000 times or a desired number of operations) will be checked.

Data Carrier with SRAM (Built-in Battery)

Battery Voltage Check

1,2,3... 1. The voltage of the Data Carrier’s built-in battery can be checked only if the

user reads the two-byte data in addresses 0000 to 0001. The Data Carrier
is not designed so that the voltage is automatically checked, because at
the time of battery check, a certain amount of current flows through the in­ternal circuitry of the Data Carrier, which in turn consumes the electricity
of the battery. We recommend the user to make a program so that the volt­age of the battery can be checked once a day.

Battery Low Check Execution Command
a) Read command
b) Auto read command

2. When the voltage of the battery is low, the DC Warning Flag (word n+4 bit

7) will be turned ON.

Data Carrier’s Life after
Generation of Battery Low
Signal

Replace the Data Carrier with a new one as soon as possible when the bat­tery low signal is turned ON, even though the Data Carrier can be used for
approximately one month after its battery low signal is turned ON.

Data Carrier with EEPROM
(With No Battery)

By counting the number of overwriting operations, it is possible to check the
life of the Data Carrier’s EEPROM. The Data Carrier’s EEPROM allows a total
of 100,000 or a desired number of overwriting operations.

!WARNING Do not throw the Data Carrier into fire or heat the Data Carrier to a tempera-

ture exceeding 100

°C. Doing so may cause ignition or burning of the built-in

lithium battery.

!WARNING Do not short the battery terminals or charge, disassemble, heat, or incinerate

the battery. Doing any of these may result in leakage, rupture, heat genera­tion, or ignition of the battery.

Note The Data Carrier with SRAM incorporates a thionyl chloride lithium battery.

The internal resistance of the thionyl chloride lithium battery will rise if the bat­tery is not used for several months, in which case, the Data Carrier will gener­ate a battery low signal if a battery check is carried out (even if the battery is
not low). When using a Data Carrier that has not been used for over a month,
carry out some trial operations for approximately 10 minutes in order to re­activate the battery. The trial operations will not significantly shorten the life of
the battery.

Program Examples Section 3-1

Operation When the command execution input is ON, the number of words in the com-

mand (7) and the beginning word where the command is stored (DM 0000)
are set using MOV, and the command execution flag (10000) is turned ON.

IR 10900 holds this status until the ID Sensor Unit begins executing the com­mand. While the ID Sensor Unit is executing the command, the ID Busy flag
(word n+4 bit 00) is set to ON. When the write operation is complete, the ID
Busy flag turns OFF.

Although the ID Busy flag normally turns OFF upon completion of the com­mand, if the command execution flag is ON at this time, the ID Busy flag will
stay ON. Therefore, design the program so that the command execution flag
will be turned OFF when the ID Busy flag turns ON, as in the example.

Program Example 2:
The Auto Write Command

Operation When the command execution input is ON, the number of words in the com-

While the ID Sensor Unit is executing the command, the ID Busy flag (word
n+4 bit 00) is turned ON. When Auto Write is complete, the ID Busy flag turns
OFF. While the ID Sensor Unit is waiting for the Data Carrier to approach, the
data Carrier waiting flag (word n+4 bit 01) is ON.

Although the ID Busy flag normally turns OFF upon completion of the com­mand, if the command execution flag is ON at this time, the ID Busy flag will
stay ON. Therefore, design the program so that the command execution flag
will be turned OFF when the ID Busy flag turns ON, as in the example.

Program Example 6:
The Auto Read/Write Abort Command

Operation When the execution command input is ON, the number of words in the com-

mand (fixed to 2 words) and the beginning word where the command is stored
(DM 0700) are set using MOV, and the command execution flag (10000) is
turned ON. IR (10905) holds the status until the ID Sensor Unit aborts the
auto command (i.e. the Data Carrier waiting flag is OFF).

While the ID Sensor Unit is executing the command, the Data Carrier waiting
flag (word n+4 bit 01) and the ID Busy flag (word n+4 bit 00) are turned OFF.
The Auto Read/Write Abort end flag (word n+4 bit 02) is turned ON, signifying
completion of the operation.

Although the ID Busy flag normally turns OFF upon completion of the com­mand, if the command execution flag is ON at this time, the ID Busy flag will
stay ON. Therefore, design the program so that the command execution flag

3-2 Monitoring

This section explains the use of the Handheld Programming Console to moni­tor data communication between the ID Sensor and the Data Carrier and to
monitor errors.

Except where otherwise noted, the operations covered in this section can only
be performed while the Handheld Programming Console is in MONITOR
mode.

3-2-1 Connecting the Handheld Programming Console

Use the C200H-PRO27E Handheld Programming Console to monitor the
operations of the ID Sensor Unit. Before connecting the Programming Con­sole to the ID Sensor Unit, turn OFF the power to the PC.

Use the optional C200H-CN222 (2 m) or C200H-CN422 (4 m) connecting
cable to connect the Handheld Programming Console to the ID Sensor Unit.
Connect the cable to the connector labeled “MONITOR” on the front panel of
the ID Sensor Unit.

Refer to the connection diagram on page 2.

Attaching the Keyboard
Sheet

Attach the keyboard sheet (provided with the ID Sensor Unit as an accessory)
as shown in the following figure.

Insert the keyboard sheet into the
slots on both sides of the keyboard,
and slide into place.

Monitoring Section 3-2

3-2-2 Mode Setting

The Handheld Programming Console can be operated in three modes; the
functions and applications of these modes are outlined in the following table.
Use the Mode selector switch on the Handheld Programming Console to
select the mode.

Note that these modes apply only to the ID Sensor Unit; they do not apply to
the CPU.

Programming Console Key Layout

Programming Console Modes

Mode Function Application

RUN In this mode, the CPU transfers data to and from the Data

Carrier according to the program in the CPU. It is a normal
operating mode only; no key input is possible.

Set the ID Sensor to RUN mode for normal
operation.

MONITOR In this mode, use Read,

Write, Continuous Write,
and Step Write to monitor
data communication
between the ID Sensor
and the Data Carrier. In
this mode, the ID Sensor
Unit operates only via
commands input from the
Handheld Programming
Comsole; commands
from the CPU are
ignored.

The ID Sensor Unit reads/
writes data directly from/to the
Data Carrier.

An easy operation test such as Read, Step
Write or Continuous Write can be performed
when installing the ID Sensor.

The ID Sensor Unit repeatedly
executes Read, Write, Auto
Read, or Auto Write. If an
error occurs, the correspond­ing error code is displayed on
the Programming Console.
(Refer to 3-2-10 Error Codes.)

Use this mode to test (TEST) and adjust the
speed of the Data Carrier and the distance
from the Read/Write Head (or Antenna).

Any communication error that
has occurred in RUN mode is
displayed on the Program­ming Console.

If an error occurs, use MONITOR mode to
determine the cause. (Refer to 3-2-9 Error
Log Display (ERR).)

PROGRAM Not used. –––

Monitoring Section 3-2

RUN Mode In this mode, the CPU transfers data to and from the Data Carrier according to

the program in the CPU. It is a normal operating mode; data cannot be input.
The following message appears on the Handheld Programming Console dis-

play.

PROGRAM Mode This mode is not used, as the ID Sensor Unit cannot be programmed. When

the mode selector on the Programming Console is set to the PROGRAM posi­tion, the following message is displayed.

MONITOR Mode When the selector is set to the MONITOR position, the following message is

displayed, indicating that the operation of the ID Sensor Unit can be moni­tored.

Note 1. The CPU program is not executed in this mode. MONITOR mode is used

specifically for monitoring operation of the ID Sensor Unit.

2. After monitoring the ID Sensor Unit, be sure to set the Handheld Program-

ming Console to RUN to resume normal operation.

MONITOR Mode
Functions and Operation

The following table gives a brief explanation of the commands used for moni­toring and their functions. Each command is explained in more detail later in
this section.

3-2-4 Address/Data Setting

Before executing the Read (READ), Step Write (WRITE 1), Continuous Write
(WRITE 2), or Test (TEST) commands, you must specify the Data Carrier
address to be accessed and the data (1 byte) to be written to that address.
This section explains the procedure for specifying the data, selecting the
addresses, and setting the addresses and data. The data and addresses that
must be set before the execution of each command are shown in the following
table.

Once the data is set in the specified address range, it will be retained until the
data is set again. Therefore, the same address can be accessed as many
times as required by pressing the command key.

Note 1. Items marked

• must be set.

2. Set an end address whose value is equal to or greater than that of the
specified start address.

Selecting Start and End
Addresses

First, select a start or end address. Refer to the diagram below in selecting
either the start address or the end address of a specific page. Once selected,
the desired values can be input.

Note This operation displays only the current addresses; it cannot be used to

change an address.

Setting Addresses First select either a start address (STadrs) or end address (EDadrs) as

described under the previous heading Selecting Start and End Addresses.
Then enter the desired value for the start address or end address. The values
can be input either directly or by using the INC/DEC keys. Refer to the follow­ing figures.

The address can also be input or changed using the INC or DEC keys, as
shown below.

When setting the address, be sure that the end address is equal to or greater
than the start address. If a value input for the end address is less than that of
the start address, the buzzer will sound and the input will not be accepted.

When the last value is input, the entire address is automatically set; it is not
necessary to press the SET key.

This section covers command processing time, which is the time required for
data communication between the Data Carrier and ID Sensor Unit; and turn­around time, which is the time required by the PC to retrieve a command and
complete the reading/writing of data from/to the Data Carrier.

Use the following table and graph to calculate the amount of time required for
executing commands involving data communication between the ID Sensor
Unit and Data Carrier.

3-3-1 Command Processing Time

Command Processing Time is the time required for data communication
between the CPU, ID Sensor, and Data Carrier.

The following graphs show the relationship between the quantity of data to be
processed and the time required for processing a command.

Timing Considerations Section 3-3

3-3-2 Turnaround Time

Turnaround time (TAT) is the elapsed time from the retrieval of a command by
the PC until the data has been read from or written to the Data Carrier. Turn­around time can be calculated as follows:

TAT = Coefficient x PC scan time + Command processing time (+ Remote I/O
communication time, if applicable)

Coefficient: Differs according to the number of bytes to be read/written and
the I/O refresh time.

PC scan time: The time required by the CPU to scan the program, refresh the
I/O area, etc. Determine this value by referring to Coefficient Values below.

Command processing time: The time required to process the communication
between the ID Sensor Unit and the Data Carrier. Determine this value by
referring to Section 3-3-1 Command Processing Time.

Remote I/O communication time: additional time required when the ID Sensor
Unit is mounted to a Remote I/O Slave Rack. If the ID Sensor Unit is not
mounted to a Remote I/O Slave Rack, this time is zero.

Coefficient Values (per execution of a single command)

1,2,3... 1. Write (Auto Write) command

Coefficient (min) = [(number of bytes of data to be transferred + 8) / 40] + 3
(Round up to next whole number.)
Coefficient (max) = Coefficient (min) + 2

2. Read (Auto Read) command
Coefficient (min) = (number of bytes of data to be transferred / 40) + 5
(Round up to next whole number.)
Coefficient (max) = Coefficient (min) + 2

3. Clear-all command
Coefficient (min) = 4
Coefficient (max) = 6

Points of Caution

Note the following points when using the C200H-IDS01-V1 or C200H-IDS21 with a CS1-series PC.

1) Differences in I/O Bit and DM Area Allocation

• The beginning word, n, of the area allocated for I/O between the CPU Unit and the ID Sensor will change
from n = 100 + (unit number

× 10) to n = 2000 + (unit number × 10).

• The beginning word, m, of the area in the DM Area allocated to the ID Sensor will change from m = DM
1000 + (unit number

× 100) to m = D20000 + (unit number × 100).

2) Command Storage Area and Read Data Receiving Area Specification

Specify the command storage area and read data receiving area for a CS1-series PC using the CIO Area
(words n+2 and n+3) in the way shown below.
