Communication protocol and communication method 

1. The user host accesses the collected value of the display table

The communication uses the standard Modbus-RTU protocol, and reads with the multi-read instruction 03H. The return parameter value is an integer with the decimal point removed from the display value of the digital tube. For example, the display value of the F0-0 digital tube is 60.0, and it is 600 if it is read by communication. There is a one-to-one correspondence between Modbus register addresses and parameters. For example, the Modbus register address corresponding to F7-2 is 0702H, that is, the 7 in F7-2 is the high 8-bit value, and the 2 in F7-2 is the low 8-bit value.

For example, read the parameter values of parameters F0-0 and F0-1 (the F7 parameter group uses the default parameters), the format is as follows:

host sends a selective dance			Slave (HXDSB0XAI) response data
Slave address is F7-0	01H		Slave address ( F7-0)	01H
Mbus function number	03H		Modbus function number	03H
Start address (high byte)	00H		Returns the number of bytes (4 bytes)	04H
Start address (low byte)	00H		High byte of address content	02H
Read word count (high byte)	00H		low byte of the content of 000 address	58H
Read word count (low byte)	02G		High byte of 0001H address content	02H
CRC (low byte)	C4H		Low byte of 0001H address content	58H
CRC (high byte)	OBH		CRC (low byte)	7AH
			CRC (high byte)	C2H

In the above example, the read F0-0 and F0-1 are 0258H = 600, that is, the collected value F0-0 is 60.0%; the displayed value F0-1 is 60.0.

 

2. Networking description between tables
Through the network between the meters, the display value of the data collected by the master meter can be transmitted to the slave meter for display through RS485. There can be only one master table in a network, and there can be multiple slave tables. In use, only the master table needs to set the corresponding display range, and the slave table does not need to set the display range.

 

Figure 4-1: The main table sends data through broadcast mode network diagram

 

Figure 4-2: Table network diagram of sending data through address polling

 

The main advantages of Figure 4-1: few setting parameters, fast networking; all slave meters only need to set one parameter.

The main advantage of Figure 4-2: Because of the polling method, each slave display table can return data. It can be roughly judged by the receiving indicator of the master meter whether all slave meters are connected to the network, but each meter needs to set parameters separately.

 

3. Serving as a slave, used as a Modbus-RTU display meter (applicable to version V1.02 and above)

Set parameter F7-4 to 1. At this time, parameters F0-1 (corresponding to register address 01H) and F0-2 (corresponding to register address 02H) parameters can be modified through the 06H and 10H commands of the Modbus-RTU protocol (the table display is no longer analogous to Quantity collection association). The device address is still set by the F7-0 parameter. The following example assumes that F7-0 = 1, F7-4 = 1 as the premise.

a. Write 16.88 data to the meter (that is, F0-1 is 1688, F0-2 is 2), and the meter will display 16.88 when it is received.

The host sends: 01 10 00 01 00 02 04 06 98 00 02 32 C5

Table response: 01 10 00 01 00 02 10 08

b. F0-2 is set to 1 through the panel parameters (the meter displays one decimal place), and the register address 01 (ie F0-1) is written with the function number 06H or 10H as 1234, and the meter displays 123.4.

Host send (06H write): 01 06 00 01 04 D2 5A 97

Table response (written by 06H): 01 06 00 01 04 D2 5A 97

or

Host send (10H write): 01 10 00 01 00 01 02 04 D2 25 1C

Table response (10H write): 01 10 00 01 00 01 50 09
