6、 Communication instructions

This device is equipped withRS232orRS485Interface, directly communicating with the computer,RS485Standard communication distance1.5kmMultiple instruments can be attached.RS232Standard communication distance15mOnly one instrument can be attached.RS232The interfaceTXDTheRXDTheGNDConnect the computer serial ports separately2、3、5Pin. The data format is1A starting position8One data bit, no checksum1A stop position.

This device adopts the standardModbus-RTUThe communication protocol can be connected to almost all configuration software, including Kingview, Power Control, Century Star, etcFixTheInTouchWaiting for domestic configuration software eliminates the hassle of users connecting to the software. The equipment to be selected when using configuration software ismodicon(*Kang)ofPLC,Modbus-RTUAddress type, data is integer type16Bit, using the Kingview register from4001At the beginning, other configuration software may be3001Start.

Read address as1The measured values of the equipment (measured values=1000）

Sending data as01 03 00 00 00 01 84 0A

The returned data is01 03 02 03 E8 B8 FA (among which03 E8—1000)，01 It is a mailing address,03It's a function number,00、00It is the starting address of the register,00、01 Read a number,84The0AIt is a verification code, returned in the dataB8 FAIt's a verification code. If you want to read two types of data: measurement value and input signal type, you can send them:01 03 00 00 00 02 C4 0B.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.

Communication measurement value return value=(measurement value+error correction) * full-scale correction. The full correction range is 0.500 to 2.000, and users can also omit this measurement error correction and directly perform error correction on the upper computer.

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.
