Shield wire

Be sure to ground only one end of the shield wire to avoid a ground loop. If both ends of the shield wire are grounded, the circuit will be closed, resulting in a ground loop. This may cause noise. Recommended cable: OTSC-VB 2PX0.5SQ (made by Onamba Co., Ltd.) or equivalent

(Use a twisted pair cable.)

Terminator (Terminal resistor)

The terminator is mounted at the end of the wire when connecting multiple peripheral devices to a personal computer. The terminator prevents signal reflection and disturbance. Do not connect a terminator to the communication line because each DCL-33A has built-in pull-up and pull-down resistors.

3. Setting Method for Communication

Press and hold the and keys (in that order) together for approx. 3 seconds in the PV/SV Display. The unit enters Auxiliary function setting mode 1. Press the key twice. “Communication protocol” will appear. Use the or key for settings or selections, and register them by pressing the key.

Now settings are complete.

4. Communication Procedure

Communication starts with command transmission from the host computer (hereafter Master), and ends with the response of the DCL-33A (hereafter Slave).

• Response with data

When the master sends the Read command, the slave responds with the corresponding set value or current status.

• Acknowledgement

When the master sends the Write 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.

(Fig. 4-1) • Broadcast address (Modbus protocol) is set.

• Communication error (framing error, parity error)

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

Communication timing between the master and slave

Master Side (Take note while programming)

When the master starts transmission through the RS-485 communication line, the master is arranged so as to provide an idle status (mark status) transmission period of 1 or more characters before sending the command to ensure synchronization on the receiving side. 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 collision of transmissions between the master and the slave, send the next command after carefully checking that the master has received the response. If a response to the command is not returned due to communication errors, set the Retry Processing to send the command again. (It is recommended to execute Retry twice or more.)

Slave Side

When the slave starts transmission through the RS-485 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 Selectable Parity: Even Selectable Stop bit: 1 bit Selectable

Error detection: Checksum

5.2 Command Configuration

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

Instrument number (Address): Numbers by which the master discerns each slave.

Instrument number 0 to 94 and Global address 95. ASCII (20H to 7FH) is 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: Codes for Write command and Read command.

Notes about Read/Write multiple pieces of data

When reading or writing multiple pieces of data, as it takes time until slave sends response data, the master determines no response based on the timeout period below after sending a command.

Timeout period calculation: 6 ms x Amount of data

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 one byte of the total value is converted to 2’s complement, and then to hexadecimal numbers, that is, ASCII code for the checksum.

• 1’s complement: Reverse each binary bit. 0 will become 1 and vice versa.

• 2’s complement: Add 1 to 1’s complement.

[Example of checksum calculation]

Write SV1 (0001H) to 600 (0258H). See (Fig. 5.3-1). Address (instrument number): 0 (20H)

6. Modbus Protocol

6.1 Transmission Mode

There are 2 transmission modes (ASCII and RTU) in Modbus protocol.

6.1.1 ASCII Mode

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 (Selectable) Parity: Even (No parity, Odd) (Selectable)

Stop bit: 1 bit (2 bits) (Selectable) Error detection : LRC (Longitudinal Redundancy Check) Data communication interval: 1 second or less

6.1.2 RTU Mode

8-bit binary data in command is transmitted as it is. Data format Start bit: 1 bit

Data bit: 8 bits Parity: No parity (Even, Odd) (Selectable) Stop bit: 1 bit (2 bits) (Selectable)

Error detection: CRC-16 (Cyclic Redundancy Check)

6.2 Data Communication Interval

6.2.1 ASCII Mode

No communication interval limit between characters

6.2.2 RTU Mode

1.5 character transmission times or less (Communication speed 2400, 4800, 9600, 19200 bps: 1.5 character transmission times, Communication speed 38400 bps: 750 s) To transmit continuously, an interval between characters which consist of one message, must be within 1.5 character transmission times. If an interval lasts longer than 1.5 character transmission times, the DCL-33A assumes that transmission from the master is finished, which results in a communication error, and will not return a response.

6.3 Message Configuration

6.3.1 ASCII Mode

ASCII mode message is configured to start by Header [: (colon) (3AH)] and end by Delimiter [CR (carriage return) (0DH) + LF (Line feed) (0AH)]. Data section: Max. 2 x 252 characters

(1) 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.

(2) Function Code

The function code is the command code for the slave to undertake one of the following actions. (Table 6.3-1)

Type Function Code Sub-Function Code Contents

03 (03H)

Reads a single or multiple piece(s) of

data from slave(s). 04 (04H) Reads information from slave(s).

06 (06H) Writes a single piece of data to slave(s).

Data access

16 (10H) Writes multiple pieces of data to slave(s).

08 (08H) 00 Echoes back the request message.

Diagnostics

43 (2BH) 14 Reads device identification information.

The 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, if 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 (Table 6.3-2) 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. (Table 6.3-2)

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 protocol error code 4 (Status unable to be written. (e.g.) AT is performing.)

18 (12H)

Shinko protocol error code 5 (During setting mode by keypad operation)

(3) Data

Data differs depending on the function code. A request message from the master is composed of a data item, amount of data and setting data. A response message from the slave is composed of the number of bytes, data and exception codes in negative acknowledgements, corresponding to the request message. The effective range of data is -32768 to 32767 (8000H to 7FFFH). Refer to Section “7. Communication Command Table” (pp.23 - 38).

(4) Error Check

ASCII Mode

fter 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.

RTU Mode

After calculating CRC-16 (Cyclic Redundancy Check) from the slave address to the end of the 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-16

In the CRC-16 system, the information is divided by the polynomial series. The remainder is added to the end of the information and transmitted. The generation of a polynomial series is as follows. (Generation of polynomial series: X16+ X15+ X2+ 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

and the

fixed value (A001H). This is assumed as X. If a carry is not generated, go to step5.

Repeat steps3and4until shifting 8 times.

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

Repeat steps3to5.

Repeat steps3to

up to the final data.

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

(1) Slave address

Slave address is an individual instrument number on the slave side, and is set within the range 1 to 95 (01H 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. Diagnostics function is disabled for the Slave address 0 (00H, broadcast address).

(2) Function code

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

Type Function Code Sub-Function Code

Contents

08 (08H) 00 (0000H) Echoes back the request message.

Diagnostics

43 (2BH) 14 (0EH) Reads device identification information.

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 0FH to the sub-function code by mistake, slave returns ABH by setting the MSB to 1, because the former is a non-existent

sub-function code. 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) Sub-function code is not correct.

2 (02H)

Illegal data address (Non-existent data address) For function code 43: Object ID is any value other than 00, 01, 02.

3 (03H)

Illegal data value (Value out of the setting range) For function code 08: Data is less than 1, or has exceeded 100. For function code 43: Read Device ID code is any value other than 01, 04.

(3) Data

Data differs depending on the function code. For the Function code 08 (08H), a request message from the master side is composed of ‘Sub-function code 2 Bytes (0000H)’ and ‘Data n x 2 Bytes’. [n: Amount of data (Max. 100)] In normal status, a response message from the slave side is the same as the request message.

7.3 Data

7.3.1 Notes about Write/Read Command

• The data (set value, decimal) is converted to a hexadecimal number. Negative numbers are represented in 2's complement.

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

• Do not use undefined Data items. If they are used, negative acknowledgement will be returned or a random value will be written or read, resulting in malfunction.

• Modbus protocol uses Holding Register addresses. The Holding Register addresses are created as follows. A Shinko command Data item is converted to decimal number, and the offset of 40001 is added. The result is the Holding Register address. Using Data item 0001H (SV1) as an example: Data item in the sending message is 0001H, however, Modbus protocol Holding Register address is 40002 (1 + 40001).

7.3.2 Write Command

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

•

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

• Writing via software communication will be possible even in the set value lock status.

• If Lock 3 is selected in [Set value lock], the written data will not be saved in the non-volatile IC memory. Therefore if the power is turned off, they will revert to their value before Lock 3.

• If an alarm type is changed in [Alarm type] (0023H, 0006H, 0007H, 0008H, 0009H), the alarm value (000BH, 0012H, 0014H, 0016H, 0018H) will default to 0 (zero). Alarm output status will also be initialized.

• Even if options are not ordered, writing via software communication will be possible. However, their command contents will not function.

• The Communication protocol, Instrument Numbers, Communication Speed, Parity and Stop bit of the slave cannot be written by software communication. They can only be set via the keypad.

• When writing a command by Global address [95 (7FH), Shinko protocol] or Broadcast address [0

(00H) Modbus protocol], the same command is sent to all the slaves connected. However, the response is not returned.

• Up to 1,000,000 (one million) entries can be stored in non-volatile IC memory.

If the number of writings exceeds the limit, the data will not be saved. So, do not change the set values frequently via communication. (If a value written via software communication is the same as the value before writing, the value will not be written in non-volatile IC memory.)

7.3.3 Read Command

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

7.4 Negative Acknowledgement

The slave will return Error code 1 (31H, Shinko protocol) or Exception code 2 (02H, Modbus protocol) in the following case:

• When non-existent data item is read or written.

The slave will return Error code 3 (33H, Shinko protocol) or Exception code 3 (03H, Modbus protocol) in the following case:

• When a value out of the setting range is written.

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

• When 0001H (AT Perform) is written for 0003H or 00E6H (AT Perform/Cancel) during PI control or ON/OFF control action

• While AT is performing, and if 0001H (AT Perform) is written for 0003H or 00E6H (AT Perform/Cancel)

• When Write is executed for Manual control MV (00E5H) during automatic control

The slave will return Error code 5 (35H, Shinko protocol) or Exception code 18 (12H, Modbus protocol) in the following case:

• During setting mode by keypad operation

7.5 Notes on Programming Monitoring Software

7.5.1 How to Speed up the Scan Time

When monitoring multiple units of the controller, set the program so that the requisite minimum pieces of data such as Data item 0080H or 0100H (PV), Data item 0081H or 0101H (OUT1 MV), Data item 0082H or 0102H (OUT2 MV), Data item 0085H (Status flag), Data item 010DH (Status flag 1), 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.

7.5.2 How to Read the Set Value Changes Made by Front Keypad Operation

If any set value is changed by the keypad operation, the controller sets 0085H (Status flag) or 010DH (Status flag 1, 215: Change in key operation) to “1 (Yes)”. There are 2 methods of reading the set value changes made by front keypad.

(1) Reading method 1

On the monitoring software side, check that 0085H (Status flag) or 010DH (Status flag 1, 215:

Change in key operation) has been set to “1 (Yes)”, then read all set values.

Clear 0085H (Status flag) or 010DH (Status flag 1, 215: Change in key operation), by writing 0001H (Clear key operation change flag) for Data item 0070H or 00FFH (Key operation change flag clearing). If 0001H (Clear key operation change flag) is written for 0070H or 00FFH (Key operation change flag clearing) during the setting mode of the controller, Error code 5 (35H, Shinko protocol) or Exception Code 18 (12H, Modbus protocol) will be returned as a negative acknowledgement. And 0085H (Status flag) or 010DH (Status flag 1, 215: Change in key operation) cannot be cleared. Set a program so that all set values can be read when a negative acknowledgement is returned.

Read all set values again after acknowledgement is returned.

(2) Reading method 2

On the monitoring software side, check that 0085H (Status flag) or 010DH (Status flag 1, 215:

Change in key operation) has been set to “1 (Yes)”, then write 0001H (Clear key operation change flag) for 0070H or 00FFH (Key operation change flag clearing).

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 still in setting mode, and read the requisite minimum pieces of data such as

0080H or 0100H (PV), 0081H or 0101H (OUT1 MV), 0082H or 0102H (OUT2 MV), 0085H

(Status flag), 010DH (Status flag 1), then return to Step1.

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.

7.5.3 How to Read PID Parameters after AT Finishes

While AT is performing, this controller sets 0085H (Status flag) or 010DH (Status flag 1, 211: During AT) to “1 (During AT)”. After AT is finished, PID parameters are updated. On the monitoring software side, check that 0085H (Status flag) or 010DH (Status flag 1, 211: During AT) has been set to “0 (OFF)”, then read parameters such as P, I, D, ARW.

7.5.4 Note When Sending All Set Values Simultaneously

• When changing alarm types at 0023H, 0006H, 0007H, 0008H or 0009H (Alarm type), the alarm values will default to 0 (zero).

First, send the selected alarm type, then send each alarm value.

• When changing input types at 0044H or 0002H (Input type), the set values such as SV1, OUT1

proportional band, Alarm value, etc. will be initialized. First, send the selected input type, then send other set values.

7.6 When Communicating with a PLC

To communicate with a PLC, use the SIF-600, Shinko PLC Interface Unit. No programming is needed for connection. However, Shinko protocol Multiple pieces of data Read (24H) and Multiple pieces of data Write (54H) are not available.

PLCs corresponding to the SIF-600, its manufacturer and host link units:

8. Set Value Digital Transmission

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

8.1 Wiring

When connecting to the PCD-33A, connect YA (-) to YA (-), YB (+) to YB (+), SG (PCD-33A) to COM (DCL-33A) respectively. Up to 31 units of the DCL-33A can be connected. The following shows a connection example of PCD-33A and DCL-33A (Fig. 8.1-1).

(Fig. 8.1-1)

8.2 Setting Method of Controllers (1) Setting the PCD-33A

If the SVTC option is added, it is not necessary to set any item. Check if Set value digital transmission [ ] is selected in [Communication protocol ( )] in Auxiliary function setting mode 1.

(2) Setting the DCL-33A

Check the following settings. (Refer to the Instruction manual for the DCL-33A.)

• Shinko protocol has been selected in [Communication protocol].

• Communication speed of the DCL-33A is identical with that of PCD-33A.

(3) The Set Value Digital Transmission starts.

Enter the SV for the program on the PCD-33A. If the program is initiated by pressing the key, SV of the PCD-33A will be transmitted to the DCL-33A. During program standby mode, 0 (zero) is sent to the DCL-33A.

10. Troubleshooting

Check that power is being supplied to the master and slave that customers use. If communication failure still occurs, check the following.

• Problem: Communication failure Check if any of the following have occurred.

Imperfect contact between the communication cable and the connector, or between the communication connector and instrument port

Incorrect wiring of the communication cable and/or connector. Communication speed of the slave does not match that of the master. The data bit, parity and stop bit of the master do not correspond to those of the slave. The instrument number (address) of the slave does not correspond to that of the command. The instrument numbers (addresses) are duplicated in multiple slaves. Make sure that the program is appropriate for the transmission timing.

• Problem: Although communication is occurring, the response is negative acknowledgement.

Check if any of the following have occurred.

A non-existent command code has been sent. The Write command data exceeds the setting range of the slave. The DCL-33A cannot be set when functions such as AT are performing. The DCL-33A is in front keypad operation setting mode.

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