Note The V600-CD1D-V2 is set to local communications mode when SW7 is ON.

New Commands The V600-CD1D-V2 incorporates the following new data management com-

mands in order to confirm the reliability of the internal data of the Data Carrier (DC).

Function Command Processing contents

Checking data MDK By adding a check code to the internal data of the DC, any data errors due to the

SRAM-type DC battery or the number of overwriting operations of the EEPROM-type DC will be detected.

MDC The MDK command is used to read the check code and the MDC command is

used to check the check code. The MDK command is always used in combination with the MDC command.

Checking the number of overwriting operations

MDL By counting the number of overwriting operations, the life of the EEPROM-type

DC will be detected. The EEPROM-type DC can be overwritten 100,000 times.

Flashing Monitor Function If an error occurs, the display for the code monitor flashes. The display does not

flash if the normal end code or warning code is returned.

Comparing the V600-CD1D-V2 and V600-CD1D-V3

The V600-CD1D-V3 conforms to EC Directives while the V600-CD1D-V2 only conforms to UL and CSA standards.

1-2 System Configuration

Being equipped with a serial interface conforming to RS-232C, the ID Controller V60-CD1D-V can communicate with general-purpose factory computers (FC) and personal computers (IBM XT/AT compatible). Communications processing is performed using the commands from a host computer (FC, IBM XT/ AT compatible) in the RUN mode.

Programmable Controller (PC)

When a command is sent from the host computer (FC, IBM XT/AT compatible) to the ID Controller, the R/W Head (or R/W Antenna) enters the stand-by state, waiting for a signal from the DC.

When a DC enters the area where it can communicate with the R/W Head, the data (model number and data for processing or inspection) of a memory area specified by the command can be written or read to or from the DC or a response transmitted to the host computer. For example, when the memory contents of the DC have been read, the host computer transmits a command on how to process or test a workpiece to a Programmable Controller (PC).

When the processing or testing has been completed, the PC transmits process or test data to the host computer.

1-4SectionUser I/O

1-4 User I/O

The ID Controller is equipped with two user outputs that can be turned ON/OFF by a command from the host controller, and also two user inputs whose ON/OFF status can be read. These I/Os can be manipulated independently of each other , so that ON/OFF signals can be processed easily and at low cost by a host computer. The following figure shows an example in which the ID Controller is used for batch reading of test data.

Outline of Operation

1, 2, 3... 1. When there is a workpiece to be tested, the PC controlling the line instructs

the conveyor to stop the workpiece at a predetermined place.

2. When the workpiece has been stopped, the PC issues a signal indicating that the line control action has been completed.

3. A host computer reads the signal to the ID Controller through a user input, and reads the test data.

4. When the test data has been read, the host computer issues a data collection completion signal through the user output of the ID Controller.

5. In response to the data collection completion signal, the PC sends the workpiece to the next process.

Modes

The ID Controller operates in two Modes: RUN and TEST Modes.

RUN Mode In this Mode, the ID Controller operates as specified upon a command sent from

the host controller, and sends the result of the operation to the host controller as a response.

Response

ID Controller

Command

Host controller

TEST Mode Communications testing can be conducted between the ID Controller and a DC

in the off-line state. The ID Controller repeatedly communicates with a DC at 1-second intervals. During communication with the DC, the HEAD Indicator lights. When the processing has been completed, an end code, which is the result of the processing, is displayed on the monitor.

Host controller

ID Controller

In the TEST Mode, two kinds of tests can be conducted: Read and Write Tests. The Read Test repeatedly reads 1-byte data, while the Write Test repeatedly writes 1-byte data. At this time, however , the contents of the DC’s data have not changed. Use this TEST Mode for initial checking of the system.

Write Command Memory

A write command executed by this Controller is recorded until either the next write command or the Power reset is executed. The write commands of the Controller include write, auto write, and polling write commands. The recorded write command can be executed by a repeat command.

Write command 1 Write command 1 Execution of Write command 1

Note Even if there are changes to the trigger input status while the ID Con-

troller is processing a command, processing is not suspended.

The condition of the trigger input can be specified to be L level (OFF) or H level (ON) by using a DIP switch.

(a) (L level active)

(d) (Trailing edge active)

flows into the ID Controller upon Power application. Take appropriate measures against the inrush current.

Use a power cable 2 mm

diameter minimum to prevent voltage drops. The use

of twisted pair cables is recommended. To improve noise immunity, ground at less than 100 Ω. For a ground cable, use a

cable of 2 mm

diameter minimum (green cable), and keep the cable length to

within 20 m.

Communication between host

computer and ID Controller

Description

1, 2, 3... 1. The host computer transmits commands to the ID Controller.

2. The ID Controller analyzes the commands from the host computer, executes lower communications, and writes/reads data to/from a DC.

3. When a read command has been executed, the ID Controller transmits the contents of the data it has read and a responds to the host computer. When a write command has been executed, the Controller transmits a response indicating the end of processing to the host computer.

Command Reception

The ID Controller assumes the following status in response to a command sent from the host computer:

Command Wait Status In this status, the ID Controller processes no command and is ready to receive

any command. In this status, the ID Controller receives and processes a read/write (including

expansion command) or auto read/write command, and returns a response to the host computer after the processing has ended. While the ID Controller is in this status, the Controller only receives a command that will terminate the current command, and an abort command.

When the ID Controller has received a polling auto command,

a) the Controller returns the result of the processing as a response to the

host computer after the processing with the DC has been completed and a polling processing inquiry command has been sent from the host computer.

b) the processing of the ID Controller can be terminated by a polling pro-

cessing termination command from the host computer.

When the ID Controller is in the polling auto subcommand wait status, it can receive only a polling subcommand (inquiry , termination) and an abort command.

Read/Write Function

Read/Write Command Processing: The read/write function is used for communication when the Data Carrier is motionless. Therefore, it must be confirmed that the Data Carrier is at a specified position, i.e., in the communication area of the R/W Head. If the Data Carrier is missing, the ID Controller returns a response to that effect.

When an ordinary auto command is executed, the ID Controller does not respond to the host computer until the Data Carrier approaches. Only when the Data Carrier approaches, the communication line between the host computer and the ID Controller becomes busy. However , when a polling auto command is executed, the ID Controller returns a response to the host computer on request. Therefore, the communication line ceases to be busy.

Specifying Data Code

Whether the read or write data is treated as an ASCII (or JIS 8) code or HEX code is specified in a command.

ASCII (JIS 8 Code)

When the data length is specified to be 7 bits by the DIP switch of the ID Controller, ASCII is specified. When the data length is specified to be 8 bits, the JIS 8 code is specified.

One character of ASCII or JIS 8 code data occupies 1 byte (1 address) of the Data Carrier memory.

Example of specifying ASCII code:

Note For ASCII (JIS 8 code), refer to Appendix A.

Hex Code

One character is treated as a hexadecimal number. Therefore, only numerals 0 through 9 and A to F can be accepted.

Two characters of data occupy 1 byte (1 address) of the Data Carrier memory. Therefore, specify data in 2-character units (in even numbers) when using a write command. If an odd number of data is specified by mistake, an error occurs.

5-4 Checking the Data Carrier Life

5-4-1 SRAM-type Data Carrier

Checking Battery Voltage Drop

1, 2, 3... 1. A voltage drop of the battery cannot always checked but can be checked

only when specific access is made.This is because, to check the battery voltage, a certain amount of current is temporarily allowed to flow through the internal circuit of the data carrier. If the battery voltage is checked each time the data carrier is accessed, the battery life is shortened. It is recommended that a routine that checks the battery once a day be incorporated in the system program.

Battery Life of Data Carrier

The Data Carrier can still be used for about 1 month under ordinary operating conditions, even if the voltage of the battery has dropped below the rated level. However, i t i s recommended that the data carrier battery be replaced with a new one as soon as possible.

5-4-2 EEPROM-type Data Carrier

The MDL command checks whether or not the EEPROM of the Data Carrier has been overwritten 100,000 times. By adding an appropriate number of overwriting operations with this command to the management area specified by the user, whether or not the EEPROM has been overwritten 100,000 times will be known.

End code 75: The number of overwriting operations has not exceeded 100,000. 76: The number of overwriting operations has exceeded 100,000.

Note: The unit number is required for 1-to-n procedure.

The management area consists of three bytes beginning with the first address of the area. It is necessary for the user to specify an appropriate number of writing operations as a dummy value when executing the MDL command. When the MDL command is executed with the appropriate number of writing operations, the number will be written to this area and if the total number (i.e., the total of the number specified by the user plus the number already accumulated in the management area) is 100,000 or over (i.e., if the value is 0186A0H or over), end code 76 as a warning will be returned. The number of overwriting operations up to the present time is accumulated as hexadecimal data in the management area. Therefore it is not possible to read the data using the read command.

If the number of overwriting operations that has been accumulated in the management area has already exceeded 100,000, the hexadecimal data value will not be renewed. In this case, only the warning will be returned when the MDL command is executed. If the MDL command is executed with 00

In each check block consisting of the first address and the number of bytes specified by the user, the area excluding the last two bytes is the calculation area and the last two-byte area is the check code area of the check block.

If check code write processing is specified with processing code K, the CRC of the data in the calculation area is calculated and the result is written to the check code area. If data collation is specified with processing code C, the CRC of the data in the calculation area is calculated and the result is compared with the data in the check code area. If the result coincides with the data in the check code area, end code 75 will be returned. If they do not coincide with each other, end code 76 will be returned as a warning.

Auto Read/Auto Write

Use of Auto Read/Auto Write Command

Generally, the read or write command is used while the DC is not moving. The auto command, in contrast, is used while the DC is moving.

Read/Write Commands

• The communication distance width is wider than when the DC is moving, so that communications can be accurately performed.

R/W Head or R/W Antenna

Not moving

Auto Read/Write Commands

• By using the auto command, the approaching or missing DC can be automatically detected.

• If the DC moving speed is low and positioning is accurate, the communication is not limited by distance (within

reason).

R/W Head or R/W Antenna

–When DC passes through the communications area of R/W Head at fixed intervals. – If a long time elapses before next DC arrives. – Overlapping of the same communication with the same DC can be avoided if wait time during which DC leaves the communication area elapses after the end of communication.

– Keep transportation speed constant. – Valid only for systems where communication is not made more than once with same DC. – Make sure that another DC does not pass through the area.

Trigger Transmits next auto command when some

trigger is received after a response is returned.

R/W Head or R/W Antenna

Trigger

– For example, auto command is transmitted after end of processing of preceding process is confirmed. – Trigger must be input before the next DC approaches.

– Trigger processing is necessary. – Make sure that the trigger is accurately input.
