COMMUNICATION INSTRUCTION MANUAL ACD-13A, ACR-13A (C5)

No. ACDR11CE1 2008.01

This manual contains instructions for communication functions of the ACD-13A, ACR-13A.

Serial communication and Console communication cannot be used together. When performing Serial communication, remove the exclusive cable (CMB) from the USB port of the PC and console connector of the ACD-13A, ACR-13A. When performing Console communication, it is not required to remove the Serial communication cables. However, do not send a command from the master side.

When using communication converter IF-400

• D-sub 9-pin connector

(Fig. 2-3)

• D-sub 25-pin connector

(Fig. 2-4)

Shielded wire

Connect only one side of the shielded wire to the FG or GND terminal so that current cannot flow to the shielded wire. If both sides of the shielded wire are connected to the FG or GND terminal, the circuit will be closed between the shielded wire and the ground. As a result, current will run through the shielded wire and this may cause noise. Be sure to ground FG or GND terminal. Recommended cable: OTSC-VB 2PX0.5SQ (made by Onamba Co., Ltd.) or equivalent (Use a twisted pair cable.)

Terminator (Terminal resistor)

Communication converter IF-400 (sold separately) has a built-in terminator. The terminator is mounted at the end of the wire when connecting a personal computer with multiple peripheral devices. The terminator prevents signal reflection and disturbance. Do not connect terminator with the communication line because each ACD/ACR-13A has built-in pull-up and pull-down resistors instead of a terminator.

4. Communication procedure

Communication starts with command transmission from the host computer (hereafter Master) and ends with the response of the ACD/ACR-13A (hereafter Slave).

• Response with data When the master sends the reading command, the slave responds with the corresponding set value or current status.

• Acknowledgement When the master sends the setting command, the slave responds by sending the acknowledgement after the processing is terminated.

• Negative acknowledgement When the master sends a non-existent command or value out of the setting range, the slave returns a negative acknowledgement.

• No response

The slave will not respond to the master in the following cases:

• Global address (Shinko protocol) is set.

• Broadcast address (Modbus protocol) is set.

• Communication error (framing error, parity error)

• Checksum error (Shinko protocol), LRC discrepancy (Modbus ASCII (Fig.4-1) mode), CRC-16 discrepancy (Modbus RTU mode)

Communication timing of the RS-485

Master side (Notice on programming)

Set the program so that the master can disconnect the transmitter from the communication line within a 1 character transmission period after sending the command in preparation for reception of the response from the slave. To avoid the collision of transmissions between the master and the slave, send the next command after carefully checking that the master received the response.

Slave side

When the slave starts transmission through a communication line, the slave is arranged so as to provide an idle status (mark status) transmission period of 1 or more characters before sending the response to ensure synchronization on the receiving side. The slave is arranged so as to disconnect the transmitter from the communication line within a 1 character transmission period after sending the response.

5. Shinko protocol

5.1 Transmission mode

Shinko protocol is composed of ASCII. Hexadecimal (0 to 9, A to F), which is divided into high order (4-bit) and low order (4-bit) out of 8-bit binary data in command is transmitted as ASCII characters. Data format Start bit : 1 bit Data bit : 7 bits Parity : Even Stop bit : 1 bit Error detection: Checksum

5.2 Command configuration All commands are composed of ASCII. The data (set value, decimal number) is represented with hexadecimal number. The negative numbers are represented with 2's complement. Numerals written below the command represent number of characters.

Header : Control code to represent the beginning of the command or the response.

ASCII codes are used. Setting command, Reading command : STX (02H) fixed Response with data, Acknowledgement : ACK (06H) fixed Negative acknowledgement : NAK (15H) fixed

Instrument number (Address): Numbers by which the master discerns each slave. Instrument number 0 to 94 and Global address 95. ASCII codes (20H to 7FH) are used by adding 20H to instrument numbers 0 to 95 (00H to 5FH). 95 (7FH) is called Global address, which is used when the same command is sent to all the slaves connected. However, the response is not returned.

Sub address : 20H fixed Command type : Code to discern Setting command (50H) and Reading command (20H) Data item : Data classification of the command object.

Composed of hexadecimal 4 digits, using ASCII. (Refer to “7. Communication command table”.) Data : The contents of data (set value) differs depending on the setting command. Composed of hexadecimal 4 digits, using ASCII. (Refer to “7. Communication command table”.)

Checksum : 2-character data to detect communication errors. (Refer to “5.3 Checksum calculation”.) Delimiter : Control code to represent the end of command

5.3 Checksum calculation

Checksum is used to detect receiving errors in the command or data. Set the program for the master side as well to calculate the checksum of the response data from the slaves so that communication errors can be checked.

The ASCII code (hexadecimal) corresponding to the characters which range from the address to that before the checksum is converted to binary notation, and the total value is calculated. The lower 2-digit of the total value are converted to 2’s complements, and then to hexadecimal figures, that is, ASCII code for the checksum.

Slave address

Slave address is an individual instrument number on the slave side and is set within the range 0 to 95 (00H to 5FH). The master identifies slaves by the slave address of the requested message. The slave informs the master which slave is responding to the master by placing its own address in the response message. Slave address 0 (00H, broadcast address) can identify all the slaves connected. However slaves do not respond.

Function code

The function code is the command code for the slave to undertake the following action types.

Function code

Contents

03 (03H) Reading the set value and information from slaves 06 (06H) Setting to slaves

Function code is used to discern whether the response is normal (acknowledgement) or if any error (negative acknowledgement) has occurred when the slave returns the response message to the master. When acknowledgement is returned, the slave simply returns the original function code. When negative acknowledgement is returned, the MSB of the original function code is set as 1 for the response. For example, when the master sends request message setting 10H to the function code by mistake, slave returns 90H by setting the MSB to 1, because the former is an illegal function. For negative acknowledgement, the exception codes below are set to the data of the response message and returned to the master in order to inform it of what kind of error has occurred.

Exception code

Contents

1 (01H) Illegal function (Non-existent function) 2 (02H) Illegal data address (Non-existent data address) 3 (03H) Illegal data value (Value out of the setting range) 17 (11H) Shinko error code 4 (Unsettable status, e.g. AT is performing) 18 (12H) Shinko error code 5 (During setting mode by keypad operation)

Data

Data differs depending on the function code. A request message from the master is composed of data item, number of data and setting data. A response message from the slave is composed of a number of bytes, data and exception codes in negative acknowledgements. The number of data to be dealt with in one message is “1”. Therefore the number of data is fixed as (30H)(30H)(30H)(31H). Effective range of data is -32768 to 32767 (8000H to 7FFFH).

Error check: 2-character data to detect communication errors.

Refer to “(2) Error check of ASCII mode”. (p.8)

Page 8

(2) Error check of ASCII mode

After calculating LRC (Longitudinal Redundancy Check) from the slave address to the end of data, the calculated 8-bit data is converted to two ASCII characters and are appended to the end of message.

How to calculate LRC

Create a message in RTU mode.

Add all the values from the slave address to the end of data. This is assumed as X.

Make a complement for X (bit reverse). This is assumed as X.

Add a value of 1 to X. This is assumed as X.

Set X as an LRC to the end of the message.

Convert the whole message to ASCII characters.

Slave address

Slave address is an individual instrument number on the slave side, and is set within the range 0 to 95 (00H to 5FH). The master identifies slaves by the slave address of the requested message. The slave informs the master which slave is responding to the master by placing its own address in the response message. Slave address 0 (00H, broadcast address) can identify all the slaves connected. However slaves do not respond.

Function code

The function code is the command code for the slave to undertake the following action types.

Function code

Contents

03 (03H) Reading the set value and information from slaves 06 (06H) Setting to slaves

When negative acknowledgement is returned, the MSB of the original function code is set as 1 for the response.

For example, when the master sends request message setting 10H to the function code by mistake, slave returns 90H by setting the MSB to 1, because the former is an illegal function. For negative acknowledgement, the exception codes below are set to the data of the response messages and returned to the master in order to inform it of what kind of error has occurred.

Data

Data differs depending on the function code. A request message from the master side is composed of data item, number of data and setting data. A response message from the slave side is composed of a number of byte, data and exception codes in negative acknowledgements. The number of data to be dealt with in one message is “1”. Therefore the number of data is fixed as (0001H). The number of response byte is (02H). Effective range of data is –32768 to 32767 (8000H to 7FFFH).

Error check: 16 bit data to detect communication errors. Refer to “(2) Error check of RTU mode”. (p.10)

Page 10

(2) Error check of RTU mode

After calculating CRC-16 (Cyclic Redundancy Check) from the slave address to the end of data, the calculated 16-bit data is appended to the end of message in sequence from low order to high order.

How to calculate CRC

In the CRC system, the information is divided by the polynomial series. The remainder is added to the end of the information and transmitted. The generation of polynomial series is as follows. (Generation of polynomial series: X

+ X

+ 1)

Initialize the CRC-16 data (assumed as X) (FFFFH).

Calculate exclusive OR (XOR) with the 1st data and X. This is assumed as X.

Shift X one bit to the right. This is assumed as X.

When a carry is generated as a result of the shift, XOR is calculated by X of 3 and the fixed

value (A001H). This is assumed as X. If a carry is not generated, go to step

Repeat steps 3 and 4 until shifting 8 times.

XOR is calculated with the next data and X. This is assumed as X.

Repeat steps 3 to 5.

Repeat steps 3 to 5 up to the last data.

Set X as CRC-16 to the end of message in sequence from low order to high order.

7. Communication command table

Data

Note on setting, reading command

• The data (set value, decimal) is converted to hexadecimal figures. A negative number is represented by 2's complement.

• When connecting plural slaves, the address (instrument number) must not be duplicated.

• Do not use the unused data items such as 0000H, 000CH. If they are used, negative acknowledgement will be returned or communication errors may occur.

• Modbus protocol uses Holding Register address. For Holding Register address, data item of Shinko protocol

is converted to decimal figures, and to which offset of 40001 is added.

(e.g.) In the case of “0001H: SV [Set value memory number 1 (SM1)]”, data item on the message to be sent is

0001H, however, Holding Register address of the Modbus protocol is 40002 (1+40001).

Setting command

• Setting range of each item is the same as that of keypad operation.

• When the data (set value) has a decimal point, a whole number (hexadecimal) without a decimal point is used.

• If the alarm type is changed during Event output EVT1 allocation (0060H) to Event output EVT5 allocation

selection (0064H), the alarm value will revert to “0”. Also alarm output status will be initialized.

• It is possible to set the set value with the setting command of the communication function even when the set

value is locked.

• Although the options are not applied, setting the items for the options is possible using the setting command.

However, they will not function.

• The instrument numbers and communication speed of the slave cannot be set by communication function.

• When sending a command by Global address [95 (7FH)], the same command is sent to all the slaves connected. However, the response is not returned.

• The memory can store up to 1,000,000 (one million) entries. If the number of settings exceeds the limit, the data will not be saved. So frequent transmission via communication is not recommended.

Reading command

• When the data (set value) has a decimal point, a whole number (hexadecimal) without a decimal point is used for a response.

Negative acknowledgement

The slave will return Error code 1 (31H) (Shinko protocol) or Exception code 1 (01H) (Modbus protocol) in the following cases.

• If AT/Auto-reset (0010H) is selected while control is in PI action or in ON/OFF action.

• When Manual MV (00D3H) is read during automatic control.

The slave will return Error code 4 (34H) (Shinko protocol) or Exception code 17 (11H) (Modbus protocol) in the following cases.

• When SV setting (00D0H) of current Set value memory number is performed during AT or program control.

• When manual MV (00D3H) is set during automatic control.

Note:

If Independent alarms such as High/Low limits independent,

High/Low limit range independent and High/Low limits with standby independent is selected during EVT1 to EVT5 allocation (0060H to 0064H), the EVT1 to EVT5 alarm value (SM1) matches the low limit side, and EVT1 to EVT5 high limit alarm value (SM1) matches the high limit side.

Set values of the Set value memory numbers (SM1 to SM15) are common to those of step numbers (1 to 15) of the Program control command. (Pages 19, 20) For Set value memory numbers (SM2 to SM15), use step numbers (2 to 15)

of the Program control command.

Notes on programming monitoring software

How to speed up the scan time

When monitoring plural units of the ACD/ACR-13A, set the program so that requisite minimum pieces of data such as PV (0A00H), OUT1 MV (0A01H), Status flag 1 (0A06H), etc. can be read. For other data, set the program so that they can be read only when their set value has changed. This will speed up the scan time.

How to read the set value change by the front keypad operation

If any set value is changed by the keypad operation, the ACD/ACR-13A sets the [Status flag 1 (0A06H) 2

: Change in key operation] to [Yes (1)]. There are 2 methods of reading the set value change by the front keypad as follows.

Reading method 1

(1) On the software side, check that [Status flag 1 (0A06H) 2

: Change in key operation] has been set to

[Yes (1)], then read all set values.

(2) Clear the [Status flag 1 (0A06H) 2

: Change in key operation], by setting the [Key operation change flag

clearing (00F0H)] to [All clearing (0001H)].

If [Key operation change flag clearing (00F0H)] is set to [All clearing (0001H)] during the setting mode of the ACD/ACR-13A, Error code 5 (35H, Shinko protocol) or Exception Code 18 (12H, Modbus protocol) will be returned as a negative acknowledgement. And [Status flag 1 (0A06H) 2

: Change in key operation]

cannot be cleared. Set a program so that all set values can be read until acknowledgement is returned.

Reading method 2

(1) On the software side, check that [Status flag 1 (0A06H) 2

: Change in key operation] has been set to

[Yes (1)], then set the [Key operation change flag clearing (00F0H)] to [All clearing (0001H)].

(2) Set the program depending on the acknowledgement or negative acknowledgement as follows.

When acknowledgement is returned;

Consider it as settings completed, and read all set values.

When Error code 5 (35H, Shinko protocol) or Exception code 18 (12H, Modbus protocol) is returned as a negative acknowledgement;

Consider it as during setting mode, and read the requisite minimum pieces of data such as PV (0A00H), OUT1 MV (0A01H), Status flag 1 (0A06H), etc. then return to step (1).

Thus, programs which do not affect the scan time can be created using the methods described above, even if set values on the monitoring software will not be updated until settings are complete.

How to read PID parameters after auto-tuning finishes

The ACD/ACR-13A sets [Status flag 1 (0A06H) 2

: AT/Auto-reset] to [During AT/Auto-reset (1)] while auto-tuning is performing. After auto-tuning is finished, PID parameters are updated. On the software side, read the parameters such as P, I, D, ARW after checking that [Status flag 1 (0A06H) 2

AT/Auto-reset] has been set to [OFF (0)].

Note when sending all set values at one time

• When changing alarm types during Event output EVT1 allocation (0060H) to Event output EVT5 allocation (0064H), alarm value will revert to “0”. First, send the selected alarm type, then send the alarm value.

• When changing input types during Input type selection (0030H), set values such as SV, OUT1 proportional band,

Alarm 1 value, etc. will be initialized. First, send the selected input type, then send other set values. When responding to the command of Input type selection, it takes approx. 2sec due to internal processing. Therefore set the Time-out time for communication to 2sec or more when executing this command.

8. Set value digital transmission

By connecting to Shinko programmable controllers [PC-900 and PCD-33A with the SVTC (Set value digital transmission) option], digital set values via the SVTC command can be received from the programmable controllers.

8.1 Wiring RS-232C (only PC-900):

Connect TX (PC-900) with RX (ACD/ACR-13A), RX (PC-900) with TX (ACD/ACR-13A) and SG with SG terminal.

RS-485:

For the PC-900, connect YA(-) with YA(-), YB(+) with YB(+), SG with SG terminal respectively. For the PCD-33A, connect YA(-) with YA(-), YB(+) with YB(+), COM with COM terminal respectively. Up to 31 units of the ACD/ACR-13A can be connected. The following shows connection example of PCD-33A and ACD/ACR-13A units.

8.2 Setting method of the programmable controller (PC-900, PCD-33A) and ACD/ACR-13A (1) Setting the PC-900 or PCD-33A

If SVTC option is added, none of the settings are required. PC-900: Check that Set value digital transmission (

) is selected during Communication mode

selection [

PCD-33A: Check that Set value digital transmission (

) is selected during Communication protocol

selection (

) in Auxiliary function setting mode 1.

(2) Setting the ACD/ACR-13A

Check the following items in the Communication group. (Refer to “3. Communication parameter setting”.) (a) Shinko protocol has been selected during Communication protocol selection. (b) Communication speed of the ACD/ACR-13A is equal to that of the PC-900 or PCD-33A.

(3) Starting Set value digital transmission

Input the program set values to the PC-900 or PCD-33A. If the program is executed by pressing the RUN key, set values of the PC-900 or PCD-33A will be sent to the ACD/ACR-13A. During program standby, “0” will be sent to the ACD/ACR-13A.

10. Troubleshooting

If any malfunctions occur, refer to the following items after checking the power supply to the master and the slave.

• Problem: Communication failure Check the following

Make sure that the communication connector is securely connected. Check that wiring of the communication connector is correct. Refer to “2. Wiring”. Burnout or imperfect contact on the communication cable and the connector.

Communication speed of the slave does not coincide with that of the master. Refer to “3. Communication parameter setting”. The data bit, parity and stop bit of the master do not accord with those of the slave. Refer to “3. Communication parameter setting”. The instrument number (address) of the slave does not coincide with that of the command. Refer to “3. Communication parameter setting”. The instrument numbers (addresses) are duplicated in multiple slaves. Refer to “3. Communication parameter setting”. Make sure that the program is appropriate for the transmission timing. Refer to “4. Communication procedure”.

•

Problem: Although communication is occurring, the response is 'NAK'.

Check the following

Check that a non-existent command code has not been sent. The setting command data exceeds the setting range of the slave. The controller cannot be set when functions such as AT are performing. The ACD/ACR-13A is in the front keypad operation setting mode.

For all other malfunctions, please contact our main office or dealers.
