9、 Communication instructions

This instrument can be equipped with RS232 and RS485 interfaces for direct communication with computers,RS485Standard Communicationdistance1.5kmMultiple instruments can be attached.RS232Standard Communicationdistance15mOnly one instrument can be attached.RS232Connect the TXD, RXD, and GND of the interface to the second, third, and fifth pins of the computer serial port, respectively. The data format consists of 1 starting bit, 8 data bits, and noneverify﹑1A stop position.To avoid communication conflicts, the instruments are all in listening mode. The computer sends a command to a certain instrument at a specified address, and then waits for a period of time for the instrument to respond. After the instrument receives the correct command, it sends out the data. After sending, the instrument is in listening mode again. In the same system, instrument addresses cannot be the same, and the baud rate must be *.

The instrument adopts the standard Modbus rtu communication protocol and supports function numbers 03 and 06. When using configuration software, the device to be selected is a Modicon PLC, Modbus RTU address type, with integer 16 bit data, starting from 4x001 or 4x000 using the Kingview register. Other configuration software may start from 3x001 or 3x000. The communication is an integer, and users need to handle the decimal places according to the actual situation.Communication transmission data is signed integer data, and it is recommended to define signed integer data for user programming. When the data is greater than0x8000When retrieving data, reverse adding is necessary1The actual value that is a negative number, for example, communication transmission data is0xFFFFThe corresponding data value is-1.For long integer data such asAccumulated quantity, etc., data value=high position×65536+Low position. During configuration, users can also choose the data type as long, and the system will automatically calculate the cumulative amount.

Read instrument data and send command format: It is recommended that the amount of data read at once should not exceed16a

On site measuring instruments return data format:

Write data to instrument and send command format: (Write to register)

Data format returned by on-site measuring instruments: (same as the data format sent)

Example: Read the first measurement value of the instrument with address 1 (PV1=1000)

Send data as 01 03 00 00 00 01 84 0A

The returned data is 01 03 02 03 E8 B8 FA (including 03 E8-1000)

(Among them, 01 is the instrument address, 03 is the function number, 00 00 is the register starting address, 00 01 represents reading a number, 840A is the checksum, and B8 FA in the returned data is the checksum. If you want to read the first and second data, you can send 01 03 00 00 02 C4 0B, and read 16 data and send 01 03 00 00 10 44 06.

The communication address range is 1-99, and the baud rate can be set to 2400 or 9600. The instrument has a default communication address of 248 (0XF8), which can be used for testing if the user is unsure. The baud rate is 2400 or 9600. After changing the communication address and baud rate, it needs to be powered on again to take effect.

The instrument has been set with a communication address of 1 and a baud rate of 9600 at the factory.

Register correspondence table (please refer to the setting section of the operating instructions for specific meanings)

Example: Read the PV (PV=1000) value of the instrument with address 1

Send data as 01 03 00 00 00 01 84 0A

The returned data is 01 03 02 03 E8 B8 FA (where 03 E8-1000), where 01 is the instrument address, 03 is the function number, 00 and 00 are the register start addresses, 00 and 01 represent reading a number, 84 and 0A are check codes, and B8 FA is the check code in the returned data. If you want to read two data, you can send 01 03 00 00 02 C4 0B.

10、 Precautions for use

1 All parameters need to be set before starting to use;

2 Power off operation should be performed when installing wiring;

3 Connect the millivolt analog signal with a shielded cable and rectifier ammeter, paying attention to positive and negative;

4 When the cumulative total safe time exceeds eight digits, it will automatically accumulate from zero;

5 Communication interfaces can be added according to user requirements;

6 If cumulative display is required by minute or second, please provide instructions when placing an order.
