Shinko BCR2, BCD2, BCS2 Communication Instruction Manual

COMMUNICATION INSTRUCTION MANUAL BCD2, BCR2, BCS2 (C5W, C5)

No. BCx2CE5 2018.02

This manual contains instructions for communication functions of the BCD2, BCR2, BCS2.

Serial communication and Console communication cannot be used together. When performing Serial communication, remove the tool cable (CMD-001) from the USB port of the PC and console connector of the BCD2, BCR2, BCS2. When performing Console communication, it is not required to remove the Serial communication cables. However, do not send a command from the master side.

Shield wire

Connect only one end of the shield to the FG terminal to avoid a ground loop. If both ends of the shield wire are connected to the FG terminal, the circuit will be closed, resulting in a ground loop. This may cause noise. Be sure to ground the FG 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 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 BCD2, BCR2, BCS2 has built-in pull-up and pull-down resistors.

3. Setting Communication Parameters

4. Communication Procedure

Communication starts with command transmission from the host computer (hereafter Master) and ends with the response of the BCx2 (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 of the RS-485

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 ms or more (*) 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.

(*) Can be set in [Response delay time] within a range of 0 to 1000 ms. (See p.5.)

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 (8 bits) Selectable Parity: Even (No parity, Odd) Selectable Stop bit: 1 bit (2 bits) 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: Code to discern Write command and Read command.

Notes about Reading/Writing multiple pieces of data

When reading/writing multiple pieces of data, as it takes time until slave sends response data, the master determines no response time based on timeout period below after sending a command. Timeout period calculation: 6 ms x Amount of data + Response delay time (*)

(*) Refer to Response delay time on p.5.

Checksum: 2-character data to detect communication errors.

Refer to 5.3 Checksum Calculation on p.9.

Delimiter: Control code to represent the end of command.

ASCII code ETX (03H) fixed

Error code: Represents an error type using ASCII.

Error Code Contents

1 (31H) Non-existent command

2 (32H) Not used

3 (33H) Value outside the setting range

4 (34H) Status unable to be written (e.g. AT is performing.)

5 (35H) During setting mode by keypad operation

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.

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

Error detection : LRC (Longitudinal Redundancy Check)

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 9600 bps, 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 BCx2 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.

Type

Function

Code

Sub-Function

Code

Contents

Data access

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).

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

Diagnostics

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

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 13H to the function code by mistake, slave returns 93H 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 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.26 to 40).

(4) Error Check

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.

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 steps

and4until shifting 8 times.

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

Repeat steps

to5.

Repeat steps

to5up 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

Diagnostics

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

(*1) For ‘Not used’ items, if a single piece of data Read/Write is executed, Error code 1 (31H, Shinko protocol) or Exception code 2 (02H, Modbus

protocol) will be returned.

(*2) The Read/Write range of setting values is different from that of keypad operation.

(*3) For writing 0005H (OUT2 proportional band), write the multiplied value (0.0 to 10.0) of OUT1 proportional band.

For reading 0005H (OUT2 proportional band), the controller internally calculates the multiplied value using OUT1 and OUT2 proportional

bands, and returns the result as response data.

Even if the multiplied value exceeds 10.0, the exceeding value will be returned as response data.

(*4) If 000BH (EV1 alarm value) or 000CH (EV2 alarm value) is changed, EVT1 high limit alarm value or EVT2 high limit alarm value will be

automatically changed to the same value.

(*5) For 0012H (Set value lock), Lock 4 and Lock 5 can be selected, which is the same as 004EH (Set value lock) of the BCx2 (p.29).

(*6) If 0013H (SV high limit) or 0014H (SV low limit) is changed, Scaling high limit or Scaling low limit will be automatically changed to the same

value.

(*7) If any action is changed at 0023H (Event output EV1 allocation) or at 0024H (Event output EV2 allocation), EV1 alarm value, EV2 alarm

value, etc. will revert to factory default value.

For the items to be initialized, refer to Section “7.7 Items to Be Initialized by Changing Settings” (p.44).

The following items cannot be selected via software communication (They can only be set via the keypad):

High/Low limits independent alarm, High/Low limit range independent alarm, High/Low limits with standby independent alarm,

Loop break alarm output, Time signal output, Output during AT, Pattern end output, Output via communication command,

Heating/Cooling control relay contact output (EV2 only)

(*8) For 0037H (Control output OFF), if Control output OFF function is not selected in [OUT/OFF key function], Error code 1 (31H, Shinko

protocol) or Exception code 2 (02H, Modbus protocol) will be returned.

(*9) For 0038H (Auto/Manual control), if Auto/Manual control is not selected in [OUT/OFF key function], Error code 1 (31H, Shinko protocol)

or Exception code 2 (02H, Modbus protocol) will be returned.

(*10) For 0039H (Manual control MV), if Write is executed during automatic control, Error code 1 (31H, Shinko protocol) or Exception code 2

(02H, Modbus protocol) will be returned.

If the following are written, Error code 3 (33H, Shinko protocol) or Exception code 3 (03H, Modbus protocol) will be returned.

• When OUT1 is in ON/OFF control, and if any items except OUT1 low limit and OUT1 high limit values are written.

• When Heating side (of Heating/Cooling control) is in ON/OFF control, and if any items – except Heating side OUT1 low limit, OUT1 high

limit value, Cooling side OUT2 low limit and OUT2 high limit value – are written.

Modbus protocol) will be returned.

(*13) For direct current output, data is not fixed.

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

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

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

• 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.

• If any action is changed at 0006H (Event output EV1 allocation) or at 0007H (Event output EV2 allocation),

the following values will revert to the factory default value:

EV1 alarm value (0012H), EV2 alarm value (0014H), etc.

For the items to be initialized, refer to Section “7.7 Items to Be Initialized by Changing Settings” (p.44).

• Writings via software communication are possible while in Set value lock status.

• Even if options are not ordered, writing or reading via software communication will be possible.

However, their command contents will not function.

• The Instrument Numbers and Communication Speed of the slave cannot be set by software communication.

They can only be set via the keypad.

• When Write is executed using the Global address [95 (7FH), Shinko protocol] command or Broadcast

address [0 (00H) Modbus protocol] command, the command is sent to all the connected slaves. However, a response is not returned.

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

7.4.1 Error code 1 (31H, Shinko protocol) or Exception code 2 (02H, Modbus protocol)

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.

7.4.2 Error code 3 (33H, Shinko protocol) or Exception code 3 (03H, Modbus protocol)

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.

7.4.3 Error code 4 (34H, Shinko protocol) or Exception code 17 (11H, Modbus protocol)

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

• When 0001H (AT/Auto-reset Perform) or 0002H (AT on startup Perform) is written at 00E6H (AT/Auto-reset Perform/Cancel) during PI control or ON/OFF control action.

• While AT is performing during Fixed value control, if 0001H (AT/Auto-reset Perform) or 0002H (AT on startup Perform) is written at 00E6H (AT/Auto-reset Perform/Cancel). While AT is performing in Fixed value control, and if 00E0H (OUT/OFF key function) is written.

• While AT is performing during Program control, if 0001H (AT/Auto-reset Perform) or 0002H (AT on startup Perform) is written at 00E6H (AT/Auto-reset Perform/Cancel). While AT is performing during Program control, and if 00E0H (OUT/OFF key function) is written.

• When 00E5H (Manual control MV) is written during automatic control

7.4.4 Error code 5 (35H, Shinko protocol) or Exception code 18 (12H, Modbus protocol)

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 0100H (PV), Data item 0101H (OUT1 MV), 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 the [010DH (Status flag 1) B15: 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 [010DH (Status flag 1) B15: Change in key operation] has been set to 1 (Yes), then read all set values.

Clear [010DH (Status flag 1) B15: Change in key operation], by writing Data item 00FFH (Key operation change flag clearing) to 0001H (Clear key operation change flag). If 00FFH (Key operation change flag clearing) is written to 0001H (Clear key operation change flag) 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 [010DH (Status flag 1) B15: 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 [010DH (Status flag 1) B15: Change in key operation] has been set to 1 (Yes), then write the 00FFH (Key operation change flag clearing) to 0001H (Clear key operation change flag).

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 0100H (PV) 0101H (OUT1 MV), 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 or ‘AT on Startup’ Finishes

While AT or ‘AT on startup’ is performing, this controller sets [010DH (Status flag 1) B9: AT/Auto-reset, AT on startup Perform/Cancel] to 1 (Perform). After AT or ‘AT on startup’ is finished, PID parameters are updated. On the monitoring software side, check that [010DH (Status flag 1) B9: AT/Auto-reset, AT on startup Perform/Cancel] has been set to 0 (Cancel), then read parameters such as P, I, D, ARW.

7.5.4 Note When Sending All Set Values Simultaneously

• When changing alarm types at 0006H (Event output EV1 allocation) or at 0007H (Event output EV2 allocation), the following values will revert to 0 (zero).

EV1 alarm value (0012H), EV2 alarm value (0014H) First, send the selected alarm type, then send each alarm value. Refer to Section ‘7.7 Items to be Initialized by Changing Settings’. (p.44)

• When changing input types at 0002H (Input type), values such as SV1, OUT1 proportional band, EV1 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 a Shinko PLC Interface Unit SIF-600. No programming is needed for connection. Shinko protocol 24H (Multiple pieces of data read command) and 54H (Multiple pieces of data write command) are not available.

8. Set Value Digital Transmission

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

8.1 Wiring

For the PC-900, connect YA (-) to YA (-), YB (+) to YB (+), COM (PC-900) to SG (BCx2) terminal respectively. For the PCD-33A, connect YA (-) to YA (-), YB (+) to YB (+), SG to SG terminal respectively. Up to 31 units of the BCS2/BCR2/BCD2 can be connected. The following shows a connection example of PCD-33A and BCS2/BCR2/BCD2.

(Fig. 8.1-1)

8.2 Setting Method of Programmable Controllers (PC-900, PCD-33A) and BCx2 (1) Setting the PC-900 or PCD-33A

If SVTC option is ordered, none of the settings are required. PC-900: Check that ‘Set value digital transmission ( )’ is selected in [Communication mode, ]. PCD-33A: Check that ‘Set value digital transmission ( )’ is selected in [Communication protocol,

] in Auxiliary function setting mode 1.

(2) Setting the BCx2

Check the following items in Engineering mode 1. Refer to Section ‘3. Setting Communication Parameters’. (pp. 4, 5)

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

• Communication speed of the BCx2 is equal to that of the PC-900 or PCD-33A (9600 bps or 19200 bps).

(3) Starting ‘Set value (SV) digital transmission’

Enter the program set values on the PC-900 or PCD-33A. If the program is executed by pressing the Key, Step SV of the PC-900 or PCD-33A will be sent to the BCx2. During program Standby, 0 (zero) will be sent to the BCx2.

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 Possible Cause Solution

Communication failure

Communication cable is not securely connected, or is disconnected/defective.

Check the communication cable and connector.

Incorrect wiring of the communication cable and/or connector

Check the communication cable and connector. Refer to Section ‘2. Wiring’ (pp. 2, 3).

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

Check the communication cable and connector.

Communication speed of the slave does not match that of the master.

Set the same communication speed on the master and the slave. Refer to Section ‘3. Setting Communication

Parameters’ (pp. 4, 5). The data bit, parity and stop bit of the master do not correspond to those of the slave.

Set the same data bit, parity and stop bit on

the master and the slave.

Refer to Section ‘3. Setting Communication

Parameters’ (pp. 4, 5). The instrument number (address) of the slave does not correspond to that of the command.

Check the instrument number (address)

of the slave and the command.

Refer to Section ‘3. Setting Communication

Parameters’ (pp. 4, 5).

The instrument numbers (addresses) are duplicated in multiple slaves.

Check that each slave has a different

instrument number (address).

Refer to Section ‘3. Setting Communication

Parameters’ (pp. 4, 5).

Make sure that the program is appropriate for the transmission timing.

Check the program.

Refer to Section ‘4. Communication

Procedure’ (p.6).

Although communication is occurring, the

response is negative acknowledgement.

A non-existent command code has been sent.

Check the command code.

The Write command data exceeds the setting range of the slave.

Check the setting range of the slave.

The controller cannot be written when functions such as AT are performing.

Check the slave status.

The BCx2 is in front keypad operation setting mode.

Return the controller to RUN mode.

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