Shield Wire
Connect only one end of the shield to the FG or GND terminal to avoid a ground loop. If both ends of theshield 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.)2

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 apersonal computer. The terminator prevents signal reflection and disturbance.
Do not connect a terminator to the communication line because each AER-102-SE has built-in pull-up
and pull-down resistors.

Command
No response(Fig.4-1)• 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 (MODBUSASCII 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 thecommand 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 tosend 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 charactertransmission period after sending the response.

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 theslaves 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 iscalculated.
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.
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)
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
ASCII Mode
Max.1 second of interval between characters
RTU Mode
Communication speed 9600 bps, 19200 bps:
To transmit continuously, an interval between characters which consist of one message, must bewithin 1.5-character transmission times.
Communication speed 38400 bps:
To transmit continuously, an interval between characters which consist of one message, must bewithin 750 s.
If an interval lasts longer than 1.5-character transmission times or 750 s, the AER-102-SE assumes
that transmission from the master is finished, which results in a communication error, and will not
return a response.

6.3 Message Configuration
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)].

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 notrespond.
6.3.2 Function CodeThe function code is the command code for the slave to undertake one of the following actions.
(Table 6.3.2-1)
Contents
Function Code03 (03H)
Reading the set value and information from slaves
06 (06H)
Setting to slaves
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 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 6.3.2-2)(Table 6.3.2-2)
Contents
Exception Code1 (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.) During Resistivity or Temperature calibration mode
18 (12H)
Shinko protocol error code 5 (During setting mode by keypad operation)
6.3.3 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 byte count, data and exception codesin negative acknowledgements.
The effective range of data is -32768 to 32767 (8000H to 7FFFH).
6.3.4 Error CheckASCII 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.
8

RTU Mode
After calculating CRC-16 (Cyclic Redundancy Check) from the slave address to the end of the data, thecalculated 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 theend 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 fixedvalue (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.

7. Communication Command Table

7.1 Note on Setting/Reading Commands• The data (set value, decimal) is converted to hexadecimal numbers.
A negative number is represented in 2's complement.
• When connecting multiple slaves, the address (instrument number) must not be duplicated.
• Data items 0200H to 0209H (User save area 1 to 10) can be read or set in 1 word units.
Effective range of data is -32768 to 32767 (8000H to 7FFFH).
• MODBUS protocol uses Holding Register addresses. The Holding Register addresses are created asfollows. 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 (Sensor cell constant) as an example: Data item in the sending message is 0001H,
however, MODBUS protocol Holding Register address is 40002 (1 + 40001).
• Even if options are not ordered, setting or reading via software communication will be possible.
However, EVT3, EVT4 and Transmission output 2 command contents will not function.
(1) 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, do not change the set values
frequently via communication. (If the value set via communication is the same as the value before thesetting, the value will not be written in non-volatile IC memory.)• Be sure to select Lock 3 when changing the set value frequently via software communication. If Lock 3
is selected, all set values – except Measurement unit, Measurement range, Resistivity calibration value,
Temperature calibration value, Transmission output 1 Zero and Span adjustment values, Transmission
output 2 Zero and Span adjustment values – can be temporarily changed. However, they revert to theirprevious value after the power is turned off because they are not saved in the non-volatile IC memory.
Do not change setting items (EVT1, EVT2, EVT3, EVT4 types). If they are changed, they will affect othersetting items.
• 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 isused.
• If EVT type is changed during selection of Data items 0005H (EVT1 type), 0050H (EVT2 type), 0051H(EVT3 type) and 0052H (EVT4 type), EVT1 to EVT4 values default to 0 (zero).
Output status of EVT1 to EVT4 will also be initialized.
• Settings via software communication are possible while in Set value lock status.
• Communication parameters such as Instrument Number, Communication Speed of the slave cannot be
set by software communication. They can only be set via the keypad.
• When sending a command using Global address [95 (7FH), Shinko protocol] or Broadcast address[00H, MODBUS protocol], the same command is sent to all the slaves connected. However, a response
is not returned.
(2) Reading Command• When the data (set value) has a decimal point, a whole number (hexadecimal) without a decimal point
is used for a response.

7.5 Notes on Programming Monitoring Software
7.5.1 How to Speed up the Scan Time
When monitoring multiple units of AER-102-SE, set the program so that the requisite minimum pieces ofdata such as Data item 0080H (Resistivity), Data item 0090H (Temperature), Data item 0081H (Status
flag 1), Data item 0091H (Status flag 2) can be read. For other data, set the program so that they can beread only when their set value has been 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 keypad operation, AER-102-SE will set [0081H (Status flag 1) 215: Change
in key operation] to 1 (Yes).
There are 2 methods of reading the set value changes made by the front keypad.
(1) Reading method 1
1 On the monitoring software side, check that [0081H (Status flag 1) 215: Change in key operation]
has been set to 1 (Yes), then read all set values.
2

Clear [0081H (Status flag 1) 215: Change in key operation], by setting Data item 007FH (Key
operation change flag clearing) to 0001H (Clear change flag).
If 007FH (Key operation change flag clearing) is set to 0001H (Clear change flag) during setting
mode of the instrument, Error code 5 (35H, Shinko protocol) or Exception Code 18 (12H, MODBUS
protocol) will be returned as a negative acknowledgement. And [0081H (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.
3 Read all set values again after acknowledgement is returned.
(2) Reading method 2
1 On the monitoring software side, check that [0081H (Status flag 1) 215: Change in key operation]
has been set to 1 (Yes), then set 007FH (Key operation change flag clearing) to 0001H (Clearchange flag).
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 0080H(Resistivity), 0090H (Temperature), 0081H (Status flag 1), 0091H (Status flag 2), then return tostep 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.
7.5.3 Note when Sending All Set Values Simultaneously• When EVT type is changed at Data items 0005H (EVT1 type), 0050H (EVT2 type), 0051H (EVT3 type)or 0052H (EVT4 type), the EVT1, EVT2, EVT3 or EVT4 value will default to 0 (zero).
The EVT1, EVT2, EVT3 or EVT4 output status will also be initialized.
First, send the EVT1, EVT2, EVT3, EVT4 type, then send the EVT1, EVT2, EVT3, EVT4 value set at
Data items 0006H (EVT1 value), 0053H (EVT2 value), 0054H (EVT3 value) and 0055H (EVT4 value).

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

Although communication
is occurring, the response
is a negative acknowledgement.

Possible Cause
Communication cable is notsecurely connected, or is
disconnected/defective.
Incorrect wiring of thecommunication cable and/or
connector
Imperfect contact between thecommunication cable and theconnector, or between thecommunication connector andinstrument port
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 correspondto that of the command.
The instrument numbers(addresses) are duplicated in
multiple slaves.
Make sure that the program isappropriate for the transmission
timing.
A non-existent command code has
been sent.
The setting command data
exceeds the setting range of theslave.
