MODBUS Protocol

The instrument adopts RS-485 Modbus communication protocol RTU mode, the serial port parameter is (N, 8, 1), that is, no check, 8-bit data, 1 stop bit, the default baud rate is 9600 (can be modified), address 01 ( Can be modified).

Protocol Description

• a) In this agreement, the letter “H” after the data indicates that the data is a hexadecimal number.
• b) All registers are double-bytes, with the high byte first and the low byte second. Integer negative numbers are represented by two’s complement, ie, -1 is represented by FFFFH and -2 is represented by FFFEH.
• c) The length of the upper computer command received by the instrument is 8 bytes, the excess part is invalid, but the first 8 bytes command is still valid. If there is a pause of 0.1 seconds, instructions that do not reach 8 bytes are considered invalid.
• d) For CRC check, please refer to the CRC worksheet. When sending, the high byte is first and the low byte is next. When the verification code is 2A2AH, the instrument passes directly without verification.

Register Overview
The instrument register is divided into three categories: floating register, parameter register and information register.

• a) The floating register data is the real-time measurement data of the instrument, such as ozone value, temperature value, etc., a total of 20 register addresses, 0000H – 0013H (decimal 0 – 19), the function code 03 or 04 can be used to read data.
  When the function code 04 is used to read the data, the measurement data returned by the meter is an integer. A data consists of two parts, the first part is the data numeric integer type, occupying a register, the second part is the data decimal places and units, sharing a register, each occupying one byte, the unit code see the unit code table.
  When accessed with function code 03, the measurement data returned by the instrument is floating point, and one data occupies two registers ( 4 bytes in total) to represent floating point data.
• b) The parameter register contains the calibration status of the instrument and some parameters that can be set by the user. A total of 40 register addresses, 0014H ~ 003BH (decimal 20 – 59), use the function code 03 to read the register data, use the function code 06 to write Registers, such as modifying the communication baud rate, instrument ID, etc.
• c) The information register contains the running status of the instrument and the basic information of the instrument, such as the instrument serial number, model, etc., a total of20 register addresses, 003CH – 004FH (decimal 60 – 79), use function code 03 to read register data, use function code 06 Write a register with writable attributes, used to control the operation of the instrument, such as the calibration operation of the instrument.
• d) The addresses of the three types of registers are arranged consecutively, but when the function code 03 is used to read the register data, the number of registers read by one instruction cannot exceed the type of the current register.

Note 1: In the partial interpretation, the corresponding meanings of the data values only list the corresponding meanings of th current value. For the corresponding meanings of other values, please refer to the detailed description of the parame-ter register.
Note 2: The temperature offset setting value or manual temperature setting value (0021H) register is determined by the tem-perature compensation type register (0020H). If the temperature compensation type is manual temperature com-pensation, this register is the manual temperature setting value. If the temperature compensation type is automatic temperature compensation, this register is the temperature offset setting value. This register is a IO-times value. For example, when 00F AH is read, it is converted to Decimal to 250, which means 25.0 “C. To write 10.0 “C to the register, you need to write the hexadecimal value corresponding to 100 0064H.

If the working mode register is read, the return value is 001 lH, that is, 0010H, indicating that the meter is currently in the measurement mode.

Calibration of Ozone
The Ozone calibration can calibrate up to two points, namely the zero point and the slope point, which is represented b y BIT0 and BITl in a 16-bit integer value binary, the corresponding relationship is shown in the following table.

	Unused	Slope	Zero
16-bit Integer	BIT15~BIT2	BIT1	BIT0

Read the calibration status register, the value corresponding to the position of the calibration point is 1, then this point has been successfully calibrated. Since the electrode must first calibrate the slope point, the calibration status register value has the following three cases:

• The value is 0000H, that is, BITl and BIT0 are all zero, no point calibration.
• The value is 0002H, that is, BITl is 1, BIT0 is zero, the slope point has been calibrated.
• The value is 0003H, that is, both BITl and BIT0 are 1, and both points have been calibrated.

Setting Mode

Users can use the host computer to send commands through the RS485 interface to make the meter enter the setting mode. In the setting mode, the meter can be restored to the factory settings. The specific operation process is as follows:

• a) Enter setting mode. Use the 06H function code to write a value (0050H) in the working mode register (address 0040H) to make the meter enter the setting mode.
  • Host computer sends: 01 06 00 40 00 50 88 22
  • Lower computer reply: 01 06 00 40 00 50 88 22
• b) Write recovery instructions. After the meter enters the setting mode, use the 06H function code to write a value
  (7FFFH) in the mode parameter register (address 0041H). The meter will clear all calibration information and restore the temperature mode and temperature offset to the default value (automatic temperature compensation, Offset 0.0 “C ), and the parameter register that needs to be restored to the default value, and then restart.

  • Lower computer reply: 01 06 00 41 7F FF B9 AE

Calibration Process

In order to ensure measurement accuracy and correctness, users need to use standard solutions to calibrate newly installed meters, or periodically calibrate meters in use. The calibration method of this instrument is to use the host computer to send commands through the RS485 interface to complete.

• a) Put the meter into the standard solution.
• b) Write the standard liquid value (slope point) or code (zero point) in the calibration status register (0043H).
• c) Wait for the calibration to complete. You can check the calibration status by reading the value of the calibration status register (0043H). The corresponding situation of reading is as follows:
  • 0: Calibrated Successfully (Returned to Measurment Mode)
  • 1: Calibrating (still in calibration mode, please read the status later).
  • 2: The correct standard value is not received within 180 seconds (the measurment mode has been returned)
  • 3: The signal cannot be stabilized or exceeds the measurement range within 180 seconds (the measurement mode has been returned).
  • 4: Sensor performance (slope or offset value) is outside the allowable range (returned to measurement mode).
• d) To calibrate other points, repeat this process.

Calibration Instructions

• a) When calibrating the ozone slope point, the standard liquid value is written into the calibration status register according to the shape. If the standard liquid is 5.00 mg / L, the hexadecimal value of 500 is written as 01F4H. When calibrating the zero point, write the zero code 0001H to the calibration status register.
• b) The ozone can be calibrated up to two points. For uncalibrated electrodes, the slope point must be calibrated first. Each time the slope point is calibrated, the meter will clear all calibration information.
• c) After successfully calibrating the slope point, the meter will calculate the slope value of the sensor. After successfully calibrating the zero point, the meter will calculate the slope of the slope point and the zero point (which will be different from the slope of the calibrated slope point only) and the zero offset. You can view the sensor performance by reading registers such as calibration and electrode slope.
• d) Write 7FFFH in the calibration status register (0043H), the meter will clear all calibration information.

Examples of Calibration Instructions

• a) Calibration slope point, such as 5.00mg / L standard liquid value 01F4H written into calibration status register (0043H)
  • Send on computer: 01 06 00 43 01 F4 78 09
  • Lower camera response: 01 06 00 43 01 F4 78 09
• b) Query calibration status, read status indicator register
  • Send on computer: 01 03 00 43 00 01 75 DE
  • Lower machine response: 01 03 02 00 00 B8 44
    For the meaning of the value underlined in the response of the lower computer, please see the explanation in the calibration process.
• c) After the calibration is completed, the device will return to the measurement state regardless of whether the calibration is successful or not. Pay attention to modify the codes of different standard solutions and recalculate the CRC. For specific instructions, please refer to the chapter of common instructions.
