CAUTION

This is a Class A instrument. In a domestic environment, this instrument may cause radio

!

interference, in which case the user may be required to take adequate measures.

This instrument is protected from electric shock by reinforced insulation. Provide

!

reinforced insulation between the wire for the input signal and the wires for instrument power supply, source of power and loads.

Be sure to provide an appropriate surge control circuit respectively for the following:

!

- If input/output or signal lines within the building are longer than 30 meters.

- If input/output or signal lines leave the building, regardless the length. This instrument is designed for installation in an enclosed instrumentation panel. All

!

high-voltage connections such as power supply terminals must be enclosed in the instrumentation panel to avoid electric shock by operating personnel.

All precautions described in this manual should be taken to avoid damage to the

!

instrument or equipment. All wiring must be in accordance with local codes and regulations.

!

All wiring must be completed before power is turned on to prevent electric shock,

!

instrument failure, or incorrect action. The power must be turned off before repairing work for input break and output failure including replacement of sensor, contactor or SSR, and all wiring must be completed before power is turned on again.

To prevent instrument damage or failure, protect the power line and the input/output lines

!

from high currents with a protection device such as fuse, circuit breaker, etc. Prevent metal fragments or lead wire scraps from falling inside instrument case to avoid

!

electric shock, fire or malfunction.

Tighten each terminal screw to the specified torque found in the manual to avoid electric

!

shock, fire or malfunction.

For proper operation of this instrument, provide adequate ventilation for heat

!

dispensation.

Do not connect wires to unused terminals as this will interfere with proper operation of the

!

instrument.

Turn off the power supply before cleaning the instrument.

* The interval time for the controller should be set to provide a time for host computer to finish

sending all data including stop bit and to switch the line to receive data. If the interval time between the two is too short, the controller may send data before the host computer is ready to receive it. In this case, communication transmission can not be conducted correctly. For a successful communication sequence to occur, the controller’s interval time must match the specifications of the host computer.

When the “1: Not settable (Lock)” is selected at the “Lock only setting items other than SV and events (EV1 to EV4)” in the set lock level, the communication parameters are not able to change the set values.

To switch the host computer from transmission to reception, send data must be on line. To check if data is on line, do not use the host computer’s transmission buffer but confirm it by the shift register.

Whether the host computer is using either the polling or selecting procedure for communication, the following processing times are required for the controller to send data:

-Response wait time after the controller sends BCC in polling procedure

-Response wait time after the controller sends ACK or NAK in selecting procedure

RS-422A/RS-485 Fail-safe

!"

A transmission error may occur with the transmission line disconnected, shorted or set to the high-impedance state. In order to prevent the above error, it is recommended that the fail-safe function be provided on the receiver side of the host computer. The fail-safe function can prevent a framing error from its occurrence by making the receiver output stable to the MARK (1) when the transmission line is in the high-impedance state.

5. RKC COMMUNICATION

The HA400/HA900/HA401/HA901 (hereafter, called controller) uses the polling/selecting method to establish a data link. The basic procedure is followed ANSI X3.28 subcategory 2.5, A4 basic mode data transmission control procedure (Fast selecting is the selecting method used in this controller).

The polling/selecting procedures are a centralized control method where the host computer

#"

controls the entire process. The host computer initiates all communication so the controller responds according to queries and commands from the host.

The code use in communication is 7-bit ASCII code including transmission control characters.

#"

The transmission control characters are EOT (04H), ENQ (05H), ACK (06H), NAK (15H), STX (02H) and ETX (03H). The figures in the parenthesis indicate the corresponding hexadecimal number.

5.1 Polling

IMR01N03-E1

Continued from the previous page.

Memory area number (3 digits)

2.

This is the identifier to specify the memory area number. It is expressed by “K01” to “K16” to each memory area number (from 1 to 16). When one column of memory area number (1 to 9) is specified, it can be specified with “K1” to “K9.” In addition, if the memory area number is assigned with “K0” or “K00”, this represents that control area is specified.

The memory area now used for control is called “Control area.”

If the memory area number is not specified when polling the identifier corresponding to the memory area, this represents that the control area is specified.

If any identifier not corresponding to the memory area is assigned with a memory area number, this memory area number is ignored.

Identifier (2 digits)

3.

The identifier specifies the type of data that is requested from the controller. Always attach the ENQ code to the end of the identifier.

For details, see

ENQ

4.

The ENQ is the transmission control character that indicates the end of the polling sequence. The ENQ must be attached to the end of the identifier. The host computer then must wait for a response from the controller.

Data is

In the following cases, the controller sends EOT to terminate the data link:

When the specified identifier is invalid

•

When there is an error in the data type

•

When data is not sent from the host computer even if the data link is initialized

•

When all the data has been sent

•

(5) No response from the controller

The controller will not respond if the polling address is not received correctly. It may be necessary for the host computer to take corrective action such as a time-out.

26

IMR01N03-E1

5. RKC COMMUNICATION

(6) ACK (Acknowledgment)

An acknowledgment ACK is sent by the host computer when data received is correct. When the controller receives ACK from the host computer, the controller will send any remaining data of the next identifier without additional action from the host computer.

For the identifier, see

5.4 Communication Items list (P. 38)

.

When host computer determines to terminate the data link, EOT is sent from the host computer.

(7) NAK (Negative acknowledge)

If the host computer does not receive correct data from the controller, it sends a negative acknowledgment NAK to the controller. The controller will re-send the same data when NAK is received. This cycle will go on continuously until either recovery is achieved or the data link is corrected at the host computer.

(8) No response from host computer

When the host computer does not respond within approximately three seconds after the controller sends data, the controller sends EOT to terminate the data link. (Time out: 3 seconds)

(9) Indefinite response from host computer

The controller sends EOT to terminate the data link when the host computer response is indefinite.

(10) EOT (Data link termination)

The host computer sends EOT message when it is necessary to suspend communication with the controller or to terminate the data link due lack of response from the controller.

6. MODBUS

The master controls communication between master and slave. A typical message consists of a request (query message) sent from the master followed by an answer (response message) from the slave. When master begins data transmission, a set of data is sent to the slave in a fixed sequence. When it is received, the slave decodes it, takes the necessary action, and returns data to the master.

6.1 Message Format

The message consists of four parts: slave address, function code, data, and error check code which are always transmitted in the same sequence.

Slave address

Function code

Data

Error check CRC-16

Slave address

!"

Message format

The slave address is a number from 0 to 99 manually set at the controller address setting switch located at the front of the controller.

For details, see

Setting the Communication Parameters (P. 15)

4.2

. Although all connected slave units receive the query message sent from the master, only the slave with the slave address coinciding with the query message will accept the message.

Function code

!"

The function codes are the instructions set at the master and sent to the slave describing the action to be executed. The function codes are included when the slave responds to the master.

!"

For details, see

Data

6.2 Function Code (P. 58)

.

The data to execute the function specified by the function code is sent to the slave and corresponding data returned to the master from the slave.

and

6.8 Data

An error checking code (CRC-16: Cyclic Redundancy Check) is used to detect an error in the signal transmission.

Error check CRC-16 (Cyclic Redundancy Check)

When sending a command message from the master, set intervals of data configuring one message to

*

time shorter than the 24 bits’ time or the 24 bits’ time plus a few milliseconds. If time intervals become time longer than the 24 bits’ time or the 24 bits’ time plus a few milliseconds, the relevant slave assumes that message sending from the master is terminated to deform the message format. As a result, the slave does not make a response.

6.4 Slave Responses

(1) Normal response

In the response message of the Read Holding Registers, the slave returns the read out data and the

•

number of data items with the same slave address and function code as the query message.

In the response message of the Preset Single Register, the slave returns the same message as the

•

query message.

In the response message of the Diagnostics (Loopback test), the slave returns the same message as

•

the query message.

In the response message of the Preset Multiple Registers, the slave returns the slave address, the

•

function code, starting number, and number of holding registers in the multi-query message.

(2) Defective message response

6. MODBUS

If the query message from the master is defective, except for transmission error, the slave returns the

•

error response message without any action.

6. MODBUS

(3) No response

The slave ignores the query message and does not respond when:

The slave address in the query message does not coincide with any slave address settings.

•

The CRC code of the master does not coincide with that of the slave.

•

Transmission error such as overrun, framing, parity and etc., is found in the query message.

•

Data time interval in the query message from the master exceeds 24 bit’s time.

•

6.5 Calculating CRC-16

The Cyclic Redundancy Check (CRC) is a 2 byte (16-bit) error check code. After constructing the data message, not including start, stop, or parity bit, the master calculates a CRC code and appends this to the end of the message. The slave will calculate a CRC code from the received message, and compare it with the CRC code from the master. If they do not coincide, a communication error has occurred and the slave does not respond.

The CRC code is formed in the following sequence:

Load a 16-bit CRC register with FFFFH.

1.

2. Exclusive OR

(⊕) the first byte (8 bits) of the message with the CRC register. Return the result to

the CRC register.

Shift the CRC register 1 bit to the right.

3.

If the carry flag is 1,

4.

exclusive OR

the CRC register with A001 hexadecimal and return the result

to the CRC register. If the carry flag is 0, repeat step 3.

Repeat step 3 and 4 until there have been 8 shifts.

5.

6. Exclusive OR

Repeat step 3 through 6 for all bytes of the message (except the CRC).

7.

The CRC register contains the 2 byte CRC error code. When they are appended to the message,

8.

the next byte (8 bits) of the message with the CRC register.

the low-order byte is appended first, followed by the high-order byte.

6. MODBUS

Example of a CRC calculation in the ‘C’ language

!"

This routine assumes that the data types ‘uint16’ and ‘uint8’ exists. Theses are unsigned 16-bit integer (usually an ‘unsigned short int’ for most compiler types) and unsigned 8-bit integer (unsigned char). ‘z_p’ is a pointer to a Modbus message, and z_messaage_length is its length, excluding the CRC. Note that the Modbus message will probably contain NULL characters and so normal C string handling techniques will not work.

uint16 calculate_crc（byte *z_p, unit16 z_message_length）

/* CRC runs cyclic Redundancy Check Algorithm on input z_p */ /* Returns value of 16 bit CRC after completion and */ /* always adds 2 crc bytes to message */ /* returns 0 if incoming message has correct CRC */

{

uint16 CRC= 0xffff; uint16 next; uint16 carry; uint16 n; uint8 crch, crcl;

while (z_messaage_length--) {

next = (uint16) *z_p; CRC ^= next; for (n = 0; n < 8; n++) {

carry = CRC & 1; CRC >>= 1; if (carry) {

CRC ^= 0xA001;

} } z_p++;

} crch = CRC / 256; crcl = CRC % 256 z_p [z_messaage_length++] = crcl; z_p [z_messaage_length] = crch; return CRC;

6.7.2 Caution for handling communication data

6. MODBUS

In this communication, the variable is handled as 4 bytes data.

•

In this communication, one variable use two register addresses (Address of high order word,

•

Address of low order word).

Turn of high order word and low order word is handled as Motorola Semiconductor type approval

•

(high order sequence of low order).

In this communication, the variables that memory area includes handles different address with for

•

control area and for setting area.

There is the following constraint in writing data in order to treat the variable as 4 bytes data in this

•

communication.

It is not possible to write only of high order word. The communication response becomes normal

−

response, but do not writing.

A writing only of low order word does sign extend and does it.

Example 1:

Example 2:

Addresses in which data (holding register) is accessible are from 0000H to 0093H, from 0200H to

•

When did a writing only of “20H” in low order word.

The controller interprets high order word as “00H.”

When did a writing only of “FFH (−1) ” in low order word.

The controller interprets high order word as “FFH.”

02E9H, and from 0500H to 0535H. If any address other than 0000H to 0093H, 0200H to 02E9H, and 0500H to 0535H is accessed, an error response message returns.

Read data of unused item is a default value.

•

Any attempt to write to an unused item is not processed as an error. Data can not be written into an

•

unused item.

If data range or address error occurs during data writing,

•

is not processed as an error. Except the

it

data that error occurred, normal data is written in data register. Therefore, it is necessary to confirm data after the end of setting data.

Communication data includes data which becomes RO (read only) depending on the specification.

•

No error occurs even if data is written when set to RO. However in this case, no data is written.

For details, see

Send the next command message at time intervals of 30 bits after the master receives the response
