四、Communication

4.1、Introduction

This product is standard equipped with RS485 communication interface, using MODBUS-RTU communication protocol. In theory, up to 32 instruments can be connected on a communication line at the same time. The communication connection should use a shielded twisted pair wire with a copper network, and the wire diameter should not be less than 0.5mm². When wiring, the communication line should be far away from the strong electric cable or other strong electric field environment, and the maximum transmission distance is 1200 meters. The typical network connection mode is shown in the figure below, and the user can choose other appropriate connection mode according to the specific situation.

Modbus RTU is an international and open fieldbus standard. As a fieldbus protocol that is easy to implement, Modbus has been successfully applied all over the world. Applications include automation in manufacturing processes, process control and building automation. Modbus protocol adopts the communication connection mode of master-slave response on a communication line. First, the host computer's signal is addressed to a unique address of the terminal (slave), and then the reply signal sent by the terminal is transmitted in the opposite direction to the host, i.e. in half-duplex mode.

Modbus protocol only allows communication between the host (PC, PLC, etc.) and terminal devices, and does not allow data exchange between independent terminal devices. In this way, terminal devices will not occupy the communication line during their initialization, but only respond to the query signal arriving at the machine.

Adopt serial communication, 8 data bits, 1 start bit, 1 stop bit, no parity bit.

The up and down commands consist of address code, function code, data area and CRC-16 check code.

The principle of high byte before, low byte after, high word before, low word after (except check code) is adopted.

Frame is the basic unit of information transmission. In Modbus protocol, the frame format of host and slave is the same.

A frame begins with a pause time of at least 3.5 bytes, which also marks the end of the frame. The entire frame must be transmitted as a continuous stream. If there is a pause of more than 1.5 bytes before the frame is completed, the slave will restart the reception of a new frame. The RTU frame format is shown below.

4.3.1、Address code（Address）

The address code is used to identify which slave communicates with the host. Each slave has a unique address code. The address code sent by the host indicates the slave address to be sent, and the address code sent by the slave indicates the slave address to be sent back. Users can use the address of 1 ~ 247, other addresses reserved.

4.3.2、Function code（Function）

The function code indicates the function to be performed by the slave. The following table lists the function codes supported by the instrument and their definitions and specific operations.

4.3.3 Data Area

Data areas vary from function code to function code. These data can be numeric values, reference addresses, etc. For example, function code 03H tells the meter to read the value of the register, then the data area must contain the start address of the register to be read and the read length.

4.3.4 Check code

Checkcheck code is used to judge whether the data received by the host or slave machine is wrong, so that the system communication is more reliable.

Modbus-RTU uses CRC-16 (16-bit cyclic redundancy check code) check method, including 16-bit binary. The CRC check code is calculated by the sender and placed at the end of the message being sent. The receiver recalculates the check code of the received message and compares it with the received check code. If the two do not match, it indicates a communication error.

Error handling

When the meter detects any error other than the error of the check code, it will send back information to the host. The highest position of the function code is 1, that is, the function code sent back from the machine to the host is added 128 on the basis of the function code sent by the host. The format of the error message returned from the machine is as follows:

The error code is as follows:

4.5.1、Read register (function code 03h)

For example, the first three high voltage contact temperature registers of the device with communication address of 01h need to be read

(Hexadecimal send) 01 03 01 08 00 03 85 F5

Frame format returned from slave station:

(Hexadecimal send) 01 03 06 00 30 00 2F 00 2F 11 64

4.5.2、Write register (function code 10h)

For example, the communication address of the device needs to be changed from 01h to 16h, and the master station sends the frame format as follows:

(Hexadecimal send) 01 10 10 60 00 01 02 00 16 3F FF

The slave station returns the frame format：

（Hexadecimal receive）16 10 10 60 00 01 06 30

五、Appendix

5.1、Read only register address table

5.2、Writable register address table

5.3、Analysis of status word

The operation display status can be viewed by reading the register with address 0101h (i.e. switch input status word)

For example, if the data read out from register 0101H is 0004 and the low byte is converted into binary number 00000100, it can be seen that only the second bit (B2) of the data is 1, which means that the test position indicates the sum and other positions are points at this time. If h read data from the register 0101 to 0029, converts the low byte to a binary number is 00101001, you can see in the data 0 (B0) and third (B3), 5 (B5) to 1, said circuit breaker closed position indicator for us at this time, work position indicator for us, and energy storage position indicator for other location for points.

In addition, the low byte corresponding to register address 0102H is the output of the relay. The output state of each relay can be viewed by reading the low byte of register address 0102H, and its data is defined as:
