COMMUNICATION FUNCTIONS
1.1
General
• This instrument provides a communication function through RS-485 and USB interface, which allows data
transmit to or receive from the host computer and other devices.
• The communication system is comprised of a master station and slave stations. Up to 31 of slave station
(present instrument) can be connected per master station (host computer, programmable controller, graphic
display panel, etc.) through RS-485 interface. USB interface enables one-to-one connection.
• Because the master station can communicate with only one slave station at a time, the destination can be
identified by the "Station No" set for each slave station.
• In order that the master station and the slave station can communicate, the format of the transmit/receive data
must coincide. In this instrument, the format of the communication data is determined by the MODBUS
protocol.

MODBUS COMMUNICATION PROTOCOL
5.1
General
The communication system by the MODBUS protocol is that the communication is always started from the
master station and a slave station responds to the received message.
Transmission procedures is as shown below.
1) The master station sends a command message to a slave station.
2) The slave station checks that the station No. in the received message matches with the own station No.
or not.
3) If matched, the slave station executes the command and sends back the response message.
4)
If mismatched, the slave station leaves the command message and wait for the next command message.

5.2
Composition of message
Command message and response message consist of 4 fields ; Station No., Function code, Data and Error
check code. And these are send in this order.
Station No. (1 byte)
Function code (1 byte)
Data (2 to 133 bytes)
Error check code (CRC-16) (2 bytes)
Fig. 5-1 Composition of message
In the following, each field is explained.
(1)
Station No.
Station No. is the number specifying a slave station. Only a slave station that corresponds to a value to
which "Station No." is set on the analyzer maintenance mode display executes a command.
(2)
Function code
This is a code to designate the function executed at a slave station.
For details, refer to section 5.4.
(3)
Data
Data are the data required for executing function codes.
codes. For details, refer to chapter 6.
The composition of data varies with function
A register number is assigned to each data in the analyzer. For reading/writing the data by
communication, designate the register number.
Note that the register number transmitted on message is expressed as its relative address.
The relative address is calculated by the following expression.




Relative address = The lower 4 digits of the Register number  – 1
For example, when the resister number designated by a function code is 40003,
Relative address
= (lower 4 digits of 40003) – 1
= 0002
is used on the message.
8
INZ-TN5A0204-E
(4)
Error check code
This is the code to detect message errors (change in bit) in the signal transmission.
On the MODUBUS protocol (RTU mode), CRC-16 (Cycric Redundancy Check) is applied.
For CRC calculation method, refer to section 5.5.
INZ-TN5A0204-E

5.3
Response of slave station
(1)
Response for normal command
To a relevant message, the slave station creates and sends back a response message which corresponds
to the command message. The composition of message in this case is the same as in section 5.2.
Contents of the data field depend on the function code. For details, refer to Chapter 6.
(2)
Response for abnormal command
If contents of a command message have an abnormality (for example, non-actual function code is
designated) other than transmission error, the slave station does not execute that command but creates
and sends back a response message at error detection.
The composition of response message at error detection is as shown in Fig. 5-2 The value used for
function code field is function code of command message plus 80H.
Table 5-1 gives error codes.

Under any of the following items, the slave station takes no action of the command message and sends
back no response.
・ A station number transmitted in the command message differs from the station number specified to
the slave station.
・ A error check code is not matched, or a transmission error (parity error, etc.) is detected.
・ The time interval between the composition data of the message becomes longer than the time
corresponding to 24 bits. (Refer to section 5.6 Transmission control procedure)

Calculation of error check code (CRC-16)
CRC-16 is the 2-byte (16-bits) error check code. From the top of the message (station No.) to the end of the
data field are calculated.
The slave station calculates the CRC of the received message, and does not respond if the calculated CRC is
different from the contents of the received CRC code.
The following shows the calculation procedure for CRC-16.
(a)
Store FFFFH into 16 bit register (CRC register).
(b) Subject the 1st byte (8 bits) of transmit message and CRC register contents to an exclusive logical
summation (XOR), and store the result into the CRC register.
(c)
Shift the CRC register contents 1 bit to the right. Store 0 at MSB.
(d) If LSB before shifting is 0, do nothing.
If LSB before shifting is 1, subject it and A001H to XOR, and store the result into the CRC register.
(e)
Repeat the steps (c) and (d) 8 times (shift by 8 bits).
(f)
Execute steps (b) to (e) for the next byte of the transmit message.
Likewise, successively repeat the steps to each byte of the transmit message.
(g) The CRC code that is retained is the value of CRC register that stands when the processing has ended for
latest byte (latest data except error code) of the transmit message.
(h) As error check code of the transmit message, store this CRC value in the order of lower 8 bits and upper 8
bits.
Transmit message (ex.)
01H
06H
00H
05H
03H
E8H
99H
75H
Successively calculate data included here
to obtain CRC. In this case, CRC = 75
99H.
Attach the error check code to

upper and lower orders.

Transmission control procedure
(1)
Transmission procedure of master station
The master station must proceed to a communication upon conforming to the following items.
(1-1)
Before sending a command message, provide 48 bits time or more vacant status.
(1-2)
For sending, the interval between bytes of a command message is below 24 bits time.
(1-3)
Within 24 bits time after sending a command message, the receiving status is posted.
(1-4)
Provide 48 bits time or more vacant status between the end of response message reception and
beginning of next command message sending [same as in (1-1)].
(1-5)
For ensuring the safety, make a confirmation of the response message and make an arrangement
so as to provide 3 times or more retries in case of no response, error occurrence, etc.
Note) The above definition is for most unfavorable value. For ensuring the safety, it’s recommended
the program of the master to work with safety factors of 2 to 3. Concretely, it is advised to
arrange the program for 38400 bps with 5 ms or more for vacant status (1-1), and within 1 ms
for byte interval (1-2) and changeover from sending to receiving (1-3).
(2) Description
1)
Detection of the message frame
The status on the line of the communication system is one of the 2 below.
(a)
Vacant status (no data on line)
(b) Communication status (data is existing)
Instruments connected on the line are initially at a receiving status and monitoring the line.
When 24 bits time or more vacant status has appeared on the line, the end of preceding frame
is assumed and, within following 24 bits time, a receiving status is posted. When data
appears on the line, instruments receive it while 24 bits time or more vacant status is detected
again, and the end of that frame is assumed. I.e., data which appeared on the line from the
first 24 bits time or more vacant status to the next 24 bits time or more vacant status is
fetched as one frame.
Therefore, one frame (command message) must be sent upon confirming the following.
(1-1) 48 bits time or more vacant status precedes before the command message sending.
(1-2) Interval between bytes of 1 command message is smaller than 24 bits time.
2)
Response of this instrument
After a frame detection (24 bits time or more vacant status), this instrument carries out processing
with that frame as a command message. If the command message is destined to the own station,
a response message is returned. Its processing time is 1 to 30 ms (depends on contents of
command message). After sending a command message, therefore, the master station must
observe the following.
(1-3) Receiving status is posted within 24 bits time after sending a command message.

Since the transmission data can not include a decimal point, data of 500.0 is
transmitted as "5000".
For transmission format of each data, refer to the Address map (Chapter 7).

ADDRESS MAP AND DATA FORMAT
7.1
Data format
7.1.1
Transmission data format
The MODBUS protocol used in this instrument is RTU (Remote Terminal Unit) mode.
Transmitted data is "numeric value" and not ASCII code".
7.1.2
Handling of decimal point position and measurement unit
When transmitted, the calibration concentration setting, alarm's high and low limits, the data of
measurement concentration value and range value have no decimal point nor measurement unit.
Calculate exact values of data upon point positioning as shown below.
(a)
Calibration concentration setting (register No. 40001 to 40020)
Alarm setting (register No. 40036 to 40055)
Range value (register No. 31077 to 31086)
You can know the point position for each Ch (channel) and each range, and unit upon reading in
the decimal point position data (register No. 31087 to 31096), and the unit data (register No.
31067 to 31076).
The decimal point position data has a value of 0, 1, 2 or 3. You can obtain an exact value by the
following calculation.
Case 0: Calibration concentration setting data /1
Case 1: Calibration concentration setting data /10
Case 2: Calibration concentration setting data /100
Case 3: Calibration concentration setting data /1000
The unit data has a value of 0, 1, 2 or 3, that corresponds as follows.
Case 0: vol%
Case 1: ppm
Case 2: mg/m3
Case 3: g/m3
For example, if:
Ch1 range-1 span calibration concentration setting (register No. 40002) = 2000,
Ch1 range-1 decimal point position (register No. 31087) = 1, and
Ch1 range-1 unit (register No. 31067) = 1,
the value is 200.0 ppm.
For writing-in, proceed in the reverse. To obtain 200.0 ppm, write 2000 as calibration
concentration setting.
The decimal point position and unit are unchangeable because fixed to each Ch and each range.
INZ-TN5A0204-E
23
(b) Measurement concentration (register No. 30001 to 30036)
The decimal point position and measurement unit for each concentration are stored in registers
following that of concentration, and can be known by reading them in.
The meaning of decimal point position data and measurement unit data values are the same as in
(a) above.
For example, if:
Ch3 measurement concentration (register No. 30007) = 1270,
Ch3 decimal point position (register No. 30008) = 2,
Ch3 measurement unit (register No. 30009) = 0,
the value is 12.70 vol%
7.1.3
Handling at measurement data over-range
Even if the measurement data is at over-range, with "— — — —" displayed on the screen, the
concentration that stands then is transmitted as read-out measurement concentration.
