Shield Wire

Be sure to ground only one end of the shield wire so that current cannot flow to the shield wire.

If both ends of the shield wire are grounded, the circuit will be closed, resulting in a ground loop.

This may cause noise. Be sure to ground the FG.

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 a personal computer with multiple peripheral devices. The terminator prevents signal reflection and disturbance.

Do not connect a terminator to the communication line because each WIL-102-SE has built-in pull-up and pull-down resistors.

Communication converter IF-400 (sold separately) has a built-in terminal resistor.

Resistivity Input Error Alarm

Resistivity input error alarm is used for detecting actuator trouble.

Even if resistivity input error alarm time has elapsed, and if resistivity input does not become higher than resistivity input error alarm band, the unit assumes that actuator trouble has occurred, and sets

Status flag 2 (EVT1, EVT2, EVT3, EVT4 output flag bit).

In Serial communication, status can be read by reading Status flag 2 (A1, A2 resistivity input error alarm output flag bit).

Resistivity input error alarm is disabled during Resistivity calibration Span adjustment.

Resistivity input error alarm is enabled only when (Resistivity input low limit action),

(Resistivity input high limit action) is selected in [A11 type], [A12 type], [A21 type] or [A22 type]. (pp.

22, 23)

9. Calibration

Resistivity Calibration Span Adjustment mode, Temperature Calibration mode and Transmission output 1 and 2 adjustment modes are described below.

9.1 Resistivity Calibration Span Adjustment Mode

Deterioration of the 2-electrode Resistivity Sensor might cause the cell constant to change.

To correct the changed cell constant, calibration is required.

Correction value is adjusted so that the resistivity matches a reference resistivity meter.

During Resistivity Calibration Span Adjustment, A action is forced OFF.

The following outlines the procedure for Resistivity Calibration Span Adjustment.

1 Press and hold the key and key (in that order) together for approx. 3 seconds in


The unit enters Resistivity Calibration Span Adjustment mode, and indicates the following.

Display Indication

Resistivity Display (CH1) and resistivity input value are displayed alternately.

Temperature Display (CH2) Resistivity Span adjustment value

2 Set the Resistivity Span adjustment value with the or key, while checking the reference resistivity meter.

Resistivity span adjustment value: 0.700 to 1.300

3 Press the key.

Resistivity span adjustment value will be registered, and the unit reverts to Resistivity/Temperature

Display Mode.

9.2 Temperature Calibration Mode

To calibrate a temperature, set a temperature calibration value.

When a sensor cannot be set at the exact location where measurement is desired, the resulting measured temperature may deviate from the temperature in the desired location. In such a case, the desired temperature can be set for the desired location by setting a temperature calibration value.

However, it is only effective within the input rated range regardless of the temperature calibration value.

Temperature after calibration = Current temperature + (Temperature calibration value)

(e.g.) When current temperature is 23.5 ,

If temperature calibration value is set to 1.5 : 23.5 + (1.5) = 25.0

If temperature calibration value is set to -1.5 : 23.5 + (-1.5) = 22.0

The following outlines the procedure for Temperature calibration.

1 Press and hold the key and key (in that order) together for approx. 3 seconds in

11.3 Communication Procedure

Communication starts with command transmission from the host computer (hereafter Master) and ends with the response of the WIL-102-SE (hereafter Slave).

Master

Command

Slave

• Response with Data

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

Data

Command

Acknowledgement

• Acknowledgement

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

Command

• Negative Acknowledgement

Negative Acknowledgement

When the master sends a non-existent command or value

out of the setting range, the slave returns a negative

Command acknowledgement.

• No Response

No response The slave will not respond to the master in the following cases:

• Global address (Shinko 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.

11.4.3 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.

11.5 MODBUS Protocol

11.5.1 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 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 bit: 8 bits

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

Stop bit: 1 bit (2 bits) (Selectable)

Error detection: CRC-16 (Cyclic Redundancy Check)

11.5.2 Data Communication Interval

ASCII Mode

Max.1 second of interval between ASCII mode characters

RTU Mode

Communication speed 9600 bps, 19200 bps:

To transmit continuously, an interval between characters which consist of one message, must be within 1.5-character transmission times.

Communication speed 38400 bps:

To transmit continuously, an interval between characters which consist of one message, must be within 750 s.

If an interval lasts longer than 1.5-character transmission times or 750 s, the WIL-102-SE assumes that transmission from the master is finished, which results in a communication error, and will not return a response.

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.

48

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 the following action types.

(Table 11.5.3-1)

Function Code

03 (03H)

Contents

Reading the set value and information from slaves

06 (06H) Setting to slaves

Function code is used to discern whether the response is normal (acknowledgement) or if any error

(negative acknowledgement) has occurred when the slave returns the response message to the master.

When acknowledgement is returned, the slave simply returns the original function code.

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

For example, when the master sends request message setting 10H to the function code by mistake, slave returns 90H by setting the MSB to 1, because the former is an illegal function.

For negative acknowledgement, the exception codes below (Table 11.5.3-2) 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 11.5.3-2)

Illegal data value (Value out of the setting range)

Shinko protocol error code 4

[Status unable to be set, (e.g. During calibration mode)]

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, amount of data and setting data.

A response message from the slave is composed of the byte count, data and exception codes in negative acknowledgements.

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

3

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.

4

5

6

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.

49

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: X 16 + X 15 + X 2 + 1)

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

2

3

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.

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

6

7

8

9

Repeat steps 3 and 4 until shifting 8 times.

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

Repeat steps 3 to 5 .

Repeat steps 3 to 5 up to the final data.

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

11.6 Communication Command Table

11.6.1 Notes about Setting/Reading Command

• 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 item 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 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 (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. A11,

A12, A21 and A22 command contents will function. However, Transmission output 1 and 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, ensure the set values are not frequently changed 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.)

• 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 their previous value after the power is turned off because they are not saved in the non-volatile IC memory. Do not change setting items (A11, A12, A21 and A22 types). If they are changed, they will affect other setting items.

• Setting range of each item (via the communication function) 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 A11, A12, A21 or A22 type is changed in [A11, A12, A21 or A22 type] (A11: 0005H, A12: 0050H,

A21: 0051H, A22: 0052H), the A11, A12, A21 or A22 value (A11: 0006H, A12: 0053H, A21: 0054H,

A22: 0055H) will default to “0.00” or “0.0”. Output status of A11, A12, A21 or A22 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 by Global address [95 (7FH), Shinko protocol] or Broadcast address

[00H, MODBUS protocol], the same command is sent to all the slaves connected. However, the 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.

11.8 Notes on Programming Monitoring Software

11.8.1 How to Speed up the Scan Time

When monitoring multiple units of the WIL-102-SE, set the program so that the requisite minimum pieces of data 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 be read only when their set value has been changed. This will speed up the scan time.

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

If any set value is changed by keypad operation, WIL-102-SE will set [0081H (Status flag 1) 2 15 :

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) 2 15 : Change in key operation] has been set to 1 (Yes), then read all set values.

2 Clear [0081H (Status flag 1) 2 15 : 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) 2 15 : 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) 2 15 : Change in key operation] has been set to 1 (Yes), then set 007FH (Key operation change flag clearing) to 0001H (Clear change 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 acknowledgemen t:

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 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.

11.8.3 Note when Sending All Set Values Simultaneously

• When A11, A12, A21 or A22 type is changed at Data item 0005H (A11 type), 0050H (A12 type),

0051H (A21 type) or 0052H (A22 type), the A11, A12, A21 or A22 value will default to “0.00” or “0.0”.

Output status of A11, A12, A21 or A22 will also be initialized.

First, send the A11, A12, A21, A22 type, then send the A11, A12, A21, A22 value at Data item

0006H (A11 value), 0053H (A12 value), 0054H (A21 value) or 0055H (A22 value).

Resistivity Calibration

Span Adjustment

Temperature

Calibration

The Resistivity Calibration Span Adjustment is performed so that the resistivity input value matches the reference resistivity meter.

When a sensor cannot be set at the exact location where measurement is desired, the resulting measured temperature may deviate from the temperature in the desired location. In such a case, the desired temperature can be set for the desired location by setting a temperature calibration value.

However, it is effective within the input rated range regardless of the temperature calibration value.

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 their previous value after the power is turned off because they are not saved in the non-volatile IC memory.

This corrects the input value from the Resistivity Sensor. When resistivity measured by the sensor may deviate from the resistivity in the measured location, desired resistivity can be obtained by adding a sensor correction value. However, it is effective within the measurement range regardless of the sensor correction value.

14. Temperature Compensation Method

14.1 How to Input Temperature Coefficient

Temperature compensation is conducted using temperature coefficient (%/ ) and a randomly selected reference temperature.

Conductivity of the solution varies depending on the temperature.

If solution temperature rises by 1 , the conductivity rises by 2% at 25 basis in general.

Temperature coefficient differs depending on the solution type and its concentration, which ranges from 0.50

to 2.50.

By inputting the temperature coefficient, temperature compensation can be calculated to find the conductivity at 25 .

Temperature coefficient 2.00 %/ can be used for most of solutions.

If temperature coefficient of solution is already-known, enter the value.

If the conductivity at an arbitrary temperature T is already-known, and if reference temperature is

ST , conductivity C

(ST) at the reference temperature can be obtained according to the following formula.

Conductivity of Deionized Water

Conductivity of deionized water is caused by dissociation of water molecules.

The dissociation of water molecules is greatly affected by the change of temperature.

Conductivity of deionized water is measured based on the characteristics in (Table 14.2-1)
