ACD/R-13A Three Position Temperature Controllers

COMMUNICATION INSTRUCTION MANUAL ACD/R-13A, ACD/R-15A (C, C5)
No. ACDR1CE8 2020.03
This manual contains instructions for communication functions of the ACD-13A, ACR-13A, ACD-15A and ACR-15A.
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/R-13A, ACD/R-15A.
When performing Console communication, it is not required to remove the Serial communication cables.
However, do not send a command from the master side.

System Configuration

1.1 RS-232C (C option) 1.2 RS-485 Multi-Drop Connection Communication (C5 option)

Wiring

2.1 RS-232C (C option)
• D-sub 9-pin connector D-sub 25-pin connector

2.2 RS-485 (C5 option)
• When using USB communication cable CMC-001-1 (sold separately)
• When using communication converter IF-400 (sold separately)

Shield wire
Connect only one end of the shield to the FG or GND terminal to avoid a ground loop. If both ends of the shield wire are connected to the FG or GND terminal, the circuit will be closed, resulting in a ground loop.
This may cause noise.
Be sure to ground the 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 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 ACD/R-13A, ACD/R-15A has built-in pull-up and pull-down resistors.

Setting Communication Parameters

Set communication parameters following the procedure below.
(1)   Set the SET key 4 times in PV/SV Display Mode.
The unit enters the Engineering group.
(2) Press the MODE key. The unit proceeds to the Input group.
(3) Press the SET key several times until characters of the Communication group appear.
(4) Press the MODE key.
The unit proceeds to ‘Communication protocol’.

• To set each setting item, use the ▲ or ▼ key.

• If the MODE key is pressed, the set value is registered, and the unit proceeds to the next setting item.
  If the MODE key is pressed at [SVTC bias], the unit proceeds to the ‘Communication protocol’.

• Pressing the key reverts to the previous setting item.

• Pressing the key for 1 sec reverts to the previous setting level (reverts from setting item to each group).

• If the MODE key is pressed for 3 seconds in any setting mode, the unit will revert to PV/SV Display Mode.

• By connecting to Shinko programmable controllers PCA1 or PCB1 (select ‘SV digital transmission’ in [Communication protocol]), the step SV can be received from programmable controllers. See Section ‘8. SV Digital Transmission’. (pp.22, 23)
•Control desired value (SV) adds SVTC bias value to the step SV. Set the value if necessary.
• Available only when ‘Shinko protocol’ is selected in [Communication protocol].
• Setting range: Converted value of 20% of the input span
DC voltage, current inputs: 20% of the scaling span (The placement of the decimal point follows the selection.)

Communication Procedure

Communication starts with command transmission from the host computer (hereafter Master), and ends with the response of the ACD/R-13A, ACD/R-15A (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 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 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 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.

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 by hexadecimal numbers.
Negative numbers are represented by 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 Setting command (50H) and Reading command (20H)
Data item:| Classification of the command object.
Composed of 4-digit hexadecimal numbers, using ASCII.
(Refer to “7. Communication Command Table”.)
Data:| The contents of data (set value) differs depending on the setting command.
Composed of 4-digit hexadecimal numbers, 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
ASCII code ETX (03H) fixed
Error code:| Represents an error type using ASCII.
1 (31H)—–Non-existent command
2 (32H)—–Not used
3 (33H)—–Setting outside the setting range
4 (34H)—–Status unable to be set (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 (instrument number) 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.

Checksum calculation example
SV: 600 (0258H)
Address (instrument number): 0 (20H)

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
1 second or less (Max.1 second of interval between characters)
6.2.2 RTU Mode
3.5 character transmission times or less
To transmit continuously, an interval between characters which consist of one message, must be within 3.5 character transmission times.
If an interval lasts longer than 3.5 character transmission times, the instrument assumes that transmission from the master is finished, resulting 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)].

Header
(:)| Slave
address| Function
code| Data| Error check
LRC| Delimiter
(CR)| Delimiter
(LF)
---|---|---|---|---|---|---

6.3.2 RTU Mode
RTU mode is configured to start after idle time is processed for more than 3.5 character transmissions, and end after idle time is processed for more than 3.5 character transmissions.

3.5 idle characters| Slave address| Function code| Data| Error check CRC-16| 3.5 idle 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 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.

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 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 set, (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 data item, number of data and setting data.
A response message from the slave is composed of the byte count, data and exception codes in negative acknowledgements, corresponding to the request message. The number of data to be dealt within 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).
(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

1. Create a message in RTU mode.
2. Add all the values from the slave address to the end of data. This is assumed as X.
3. Make a complement for X (bit reverse). This is assumed as X.
4. Add a value of 1 to X. This is assumed as X.
5. Set X as an LRC to the end of the message.
6. 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 + X 15 + X 2 + 1)

1. Initialize the CRC-16 data (assumed as X) (FFFFH).
2. Calculate exclusive OR (XOR) with the 1st data and X. This is assumed as X.
3. Shift X one bit to the right. This is assumed as X.
4. 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 5.
5. Repeat steps 3 and 4 until shifting 8 times.
6. XOR is calculated with the next data and X. This is assumed as X.
7. Repeat steps 3 to 5.
8. Repeat steps 3 to 5 up to the final data.
9. Set X as CRC-16 to the end of message in sequence from low order to high order.

Communication Command Table

About Data
Notes about setting and reading commands

• [13A] is entered in the Data item for the exclusive commands of the ACD/R-13A.
  [15A] is entered in the Data item for the exclusive commands of the ACD/R-15A.
  [13A] or [15A] is not entered in the Data Item for common commands to ACD/R-13A, ACD/R-15A.
  Be sure to use exclusive commands correctly as described above, otherwise actions will not be guaranteed.

• The data (set value, decimal) is converted to hexadecimal numbers. Negative numbers are represented by 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 set 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 SV [Set value memory number 1 (SM1)] as an example: Data item in the sending message is 0001H, however, MODBUS protocol Holding Register address is 40002 (1 + 40001).

Setting 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 ensure the set values are not frequently changed via the software. (If the value set via the software is the same as the value before the setting, the value will not be set in non-volatile IC memory.)

• Setting range of each item (via the software) is the same as when setting via the keypad.

• 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 in [Event output EVT1 allocation (0060H)] to [Event output EVT5 allocation (0064H)], the alarm value will default to 0 (zero). Alarm output status will also return to the factory default.

• Settings via software communication are possible even in the Set value lock status.

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

• Communication parameters such as Instrument Number, Communication Speed of the slave cannot be set using the software. They can only be set via the keypad. See p.3.

• When sending a setting command using the Global address [95 (7FH), Shinko protocol] or Broadcast address [(00H) MODBUS protocol], the command is sent to all the connected slaves. However, no response is returned.

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 control or in ON/OFF control 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 (00D0H) of current Set value memory number is set 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) are selected in [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.
The 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. (p.19)
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 multiple units of the controller, set the program so that the requisite minimum pieces of data such as Data item 0A00H (PV), Data item 0A01H {OUT1 MV [13A]/Output MV [15A]}, Data item 0A06H (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.
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 [0A06H (Status flag 1) 2 15  : 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

1. On the monitoring software side, check that [0A06H (Status flag 1) 2 15: Change in key operation] has been set to 1 (Yes), then read all set values.

2. Clear the [0A06H (Status flag 1) 2 15  : Change in key operation], by setting Data item 00F0H (Key operation change flag clearing) to 0001H (Clear all).
   If 00F0H (Key operation change flag clearing) is set to 0001H (Clear all) 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 [Status flag 1 (0A06H) 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.

3. Read all set values again after acknowledgement is returned.

(2) Reading method 2

1. On the monitoring software side, check that [0A06H (Status flag 1) 2 15: Change in key operation] has been set to [1: Yes], then set the [Key operation change flag clearing (00F0H)] to 0001H (Clear all).
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 still in setting mode, and read the requisite minimum pieces of data such as PV (0A00H), OUT1 MV [13A] / Output MV [15A] (0A01H), Status flag 1 (0A06H), 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 AT finishes
The controller sets [0A06H (Status flag 1) 2 13 : AT/Auto-reset] to [1: During AT/Auto-reset] while AT is performing.
After AT is finished, PID parameters are updated.
On the monitoring software side, read the parameters such as P, I, D, ARW after checking that [0A06H (Status flag 1) 213 : AT/Auto-reset] has been set to [0: OFF].
Note when sending all set values simultaneously
• When changing alarm types in [Event output EVT1 allocation (0060H)] to [Event output EVT5 allocation (0064H)], alarm value will revert to 0 (zero). First, send the selected alarm type, then send the alarm value.
• When changing input types at [Input type (0030H)], the set values such as SV, OUT1 proportional band [13A] /
Proportional band [15A], Alarm 1 value, etc. will return to the factory default.
First, send the selected input type (0030H), then send other set values.
When responding to the command of Input type selection, it takes approx. 2 seconds due to internal processing.
Therefore, set the Time-out time for communication to 2 seconds or more when executing this command.
When communicating with a PLC
To communicate with a PLC, use a Shinko PLC Interface Unit SIF-600.
No programming is needed for connection.
PLCs corresponding to the SIF-600:

SV Digital Transmission

By connecting to Shinko programmable controllers PCA1 or PCB1 (select ‘SV digital transmission’ in [Communication protocol]), the Step SV can be received from programmable controllers.
8.1 Wiring
RS-232C (only for PCA1):
Connect TX (PCA1) to RX (ACD/R-13A,
ACD/R-15A), RX (PCA1) to TX (ACD/R-13A,
ACD/R-15A) and COM (PCA1) to SG (ACD/R-13A,
ACD/R-15A) terminal.
The following shows connection example between the PCA1 and ACD/R-13A, ACD/R-15A. (Fig. 8.1-1)

RS-485:
For the PCA1, connect YA(-) to YA(-), YB(+) to YB(+),COM to SG terminal respectively.
For the PCB1, connect YA(-) to YA(-), YB(+) to YB(+),SG to SG terminal respectively.
Up to 31 units of the ACD/R-13A or ACD/R-15A can be connected.
The following shows a connection example of PCB1 and ACD/R-13A, ACD/R-15A. (Fig. 8.1-2)

8.2 Setting Method of Programmable Controllers (PCA1 or PCB1) and ACD/R-13A, ACD/R-15A
(1) Setting the PCA1 or PCB1
Select ‘SV digital transmission’ in [Communication protocol].
(2) Setting the ACD/R-13A, ACD/R-15A
Check the following in the Communication group. Refer to “3. Setting Communication Parameters”. (p.3)

• Shinko protocol has been selected in [Communication protocol].
• Communication speed of the ACD/R-13A or ACD/R-15A is equal to that of the PCA1 or PCB1 (9600 or 19200 bps).

(3) Starting SV digital transmission
Enter the program set values on the PCA1 or PCB1.
If the program is executed by pressing the RUN Key, the step SV of the PCA1 or PCB1 will be sent to the ACD/R-13A, ACD/R-15A.
If SVTC bias value is set, SV adds SVTC bias value to the step SV (received from PCA1 or PCB1 via SVTC command).
During program standby, 0 (zero) will be sent to the ACD/R-13A, ACD/R-15A.
