Connect only one side of the shielded wire to FG so that no current flows in the shield part. If both sides of the shield are connected to FG, a closed circuit will be created between the shielded wire and the ground, and a current will flow through the shielded wire, making it more susceptible to noise. Be sure to ground FG. Recommended cable: OTSC-VB 2PX0.5SQ by Onamba Co., Ltd. or equivalent (use twisted pair
shielded wire).

Termination resistor (terminator) The communication converter IF-400 (sold separately) has a built-in termination resistor. The termination resistor is also called a terminator. It is a resistor attached to the end of wiring when peripheral devices are connected to the host computer in a chain, and prevents signal reflection and signal disturbance at the end. Since this instrument has a built-in pull-up resistor and pull-down resistor, no termination resistor is required on the communication line.

9 Communication Procedure

Communication starts with command transmission from the host computer (hereafter Master), and ends with

the response of this instrument (hereafter Slave).

Master

Slave

Command Data

Command

· 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

Command

sending the acknowledgement after the processing is terminated. · Negative acknowledgement

When the master sends a non-existent command or value out of the

Command No response

setting range, the slave returns a negative acknowledgement. · No response
The slave will not respond to the master in the following cases:

(Fig. 8.2-1)

· Broadcast address is set.

· Communication error (framing error, parity error)

· CRC-16 discrepancy

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 “Communication response delay time setting (P.8-13)” within a range of 0 to 1000 ms.

1.5 character transmission times or less (Communication speed 9600 bps, 19200 bps: 1.5 character transmission times, Communication speed 38400 bps, 57600 bps: 750 µs) To transmit continuously, an interval between characters which consist of one message, must be within 1.5 character transmission times. If the time is longer than the above, it is assumed that transmission from the master side has finished, and a communication error occurs and no response is returned.

10.3 Message Configuration

Message 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.

(Communication speed 9600 bps, 19200 bps: 3.5 character transmission times,

Communication speed 38400 bps, 57600 bps: 1.75 ms)

The data part has a maximum of 252 bytes.

(1) Slave Address Slave address is an individual instrument number on the slave side, and is set within the range 1 to 16 (01H to 10H). 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)
06(06H) 16(10H)

Reads a single or multiple piece(s) of data from slave(s) (Amount of data: Max. 100).
Writes a single piece of data to slave(s).
Writes multiple pieces of data to slave(s) (Amount of data: Max. 20).

10-1

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.

(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 codes in negative acknowledgements, corresponding to the request message. The effective range of data is -32768 to 32767 (8000H to 7FFFH). Refer to “11.1 Communication Command List (P.11-1)”.
(4) Error Check 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 step . Repeat steps and until shifting 8 times. XOR is calculated with the next data and X. This is assumed as X. Repeat steps to . Repeat steps to up to the final data. Set X as CRC-16 to the end of message in sequence from low order to high order.

11.2 Data
11.2.1 Notes About Write/Read Command · The data (set value, decimal) is converted to a hexadecimal number. Negative numbers are represented in 2’s complement. · 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 data item is converted to decimal number, and the offset of 40001 is added. The result is the Holding Register address. Using CH1 Output volume setting (0014H) as an example: Data item in the sending message is 0014H, however, MODBUS protocol Holding Register address is 40021 (20+40001).
11.2.2 Write Command · The lifetime of the non-volatile IC memory is about 1 trillion times. Do not change the set value frequently by communication, as the set value storage retention time may be shortened if the number of times is exceeded. (If the set value is the same as the value before setting, it is not written to the non-volatile IC memory.) · When data (set value) has a decimal point, a whole number (hexadecimal) without a decimal point is used. · Communication parameters such as module address and communication speed of this instrument cannot be written by software communication. Set it with the rotary switch for module address selection and the dip switch for selecting communication specifications. · When Write is executed using the Broadcast address [(00H) MODBUS protocol] command, the command is sent to all the connected slaves. However, a response is not returned.
11.2.3 Read Command · When the data (set value) has a decimal point, a whole number (hexadecimal) without a decimal point is used for a response.
11.3 Negative Acknowledgement
11.3.1 Error Code 2 (02H) The slave will return Error code 2 (02H) in the following case. · When non-existent data item is read or written.
11.3.2 Error Code 3 (03H) The slave will return Error code 3 (03H) in the following case. · When a value out of the setting range is written.
11.3.3 Error Code 17 (11H) The slave will return Error code 17 (11H) in the following case. · In the case of a condition that cannot be written.

12.2 Correct PV
When a sensor cannot be mounted at a location to be controlled, the temperature measured by the sensor may differ from the temperature at the measurement location. Also, when multiple analog I/O modules are used for measurement, the measured temperatures may not match due to the accuracy of the sensors. In such cases, the temperature measured by the sensor can be corrected to match the PV of the analog I/O module with the desired temperature.
The input value is corrected by the sensor correction factor and the sensor correction. The sensor correction factor sets the slope, and the sensor correction sets the difference between before and after correction.
PV after input correction is expressed by the following formula. PV after input correction = Current PV × Sensor correction factor setting value + (Sensor correction setting value)
An example of input value correction using a combination of Sensor correction factor and Sensor correction is shown below.

750°C 700°C
340°C 300°C

Y Y’ Corrected from 750°C to 700°C
X’ X Corrected from 300°C to 340°C

300°C

750°C

Slope before correction

Slope after correction

(1) Extract two points to be corrected and determine the PV after correction. Before correction: 300°C After correction: 340°C Before correction: 750°C After correction: 700°C
(2) Find the sensor correction factor setting value from (1). (Y’ – X’) / (Y – X) = (700 – 340) / (750 – 300) = 0.8
(3) It is input so that PV will be 300°C using a mV generator and dial resistor. (4) Set the value of (2) to the sensor correction factor. (5) Read PV.
It is displayed as 240°C. (6) Find the sensor correction setting value.
Find the difference between the PV after input correction and the PV read in (5). 340°C – 240°C = 100°C (7) Set the value of (6) to the sensor correction. (8) Input an electromotive force or resistance value equivalent to 750°C using a mV generator or dial resistor. (9) Read PV and check that the display is 700°C.

13 Communication with PLC Using SIF Function
The SIF function (Smart InterFace, programless communication function) is a function that serially connects the PLC Q series (manufactured by Mitsubishi Electric Corp.) and this instrument, and reads and writes various data to and from PLC registers using the communication protocol of the PLC. The following communication protocols and commands are supported.

Communication protocol Communication command

Format 4 A compatible 1C frame AnA/AnU common command (QR/QW)

Using the console software (SWC-QTC101M), select the PLC register start number, PLC register address, the monitoring items and setting items to be linked, and set the specifications.

The control module QTC1-2P (with power supply / communication options) or QTC1-4P (with power supply / communication options) becomes the master and the selected monitor item is periodically written to the PLC register using the QW command, and the PLC register value is constantly updated. In addition, the selected setting items are read from the PLC register in response to a setting request using the QR command. When the read data is changed, the set value of control module QTC1-2P (with power / communication option) or QTC1-4P (with power supply / communication option) and analog I/O module QAM1-40 (no power supply / communication option) is updated.

(Fig. 13.7-1)
13.7.1 Communication Procedure (1) The control module QTC1-4P becomes the master and collects the valid monitor items and setting items of the analog I/O module QAM1-40 (slave). (2) After the PLC communication start waiting time has elapsed, the control module QTC1-4P periodically writes the item selected in the monitor items to the PLC register. Also, the item selected from the setting items is read from the PLC register in response to a setting request.
