(1) RS485 Communication interface, asynchronous half duplex mode。
(2) 4800,9600bps baud rate can be set, the factory default value is 9600 BPS。
(3) Byte transfer format: N81 no parity bit 1 data bits 8 stop bits。
6．1．2 communication protocolModbus-RTU
This instrument provides serial asynchronous half duplex RS485 communication interface, using standard MODBUS-RTU protocol, all kinds of data and information can be found in the communication line transmission. In a line can also connect up to 64 network instrument, each network meter can set the address and communication even collusion with copper net shielded twisted pair, wire diameter not less than wiring 0.5mm2. should enable communication line away from the high voltage cable, or other strong electric field environment, recommended the use of the T type network connection, does not recommend the use of a star or other connection。
MODBUSBetween terminal equipment protocol in a communication line using master-slave response mode of communication connection mode. First of all, the main computer signal is addressed to only allowing communication between the host (PC, PLC, etc.) and the terminal equipment of a unique address terminal equipment (slave), then sent from the terminal unit of the response signal transmission in the opposite direction to the host, namely: in a single communication line signal along the opposite direction of transmission all communication data flow (half duplex mode) protocol. MODBUS without allowing independent data exchange, this kind of the terminal device does not initialize them occupy the communication line , but only in response to the machine's query signal。

Host queries: query message frame including device address, code and data information code, check code. Address code that is selected from machine equipment; functional code tell is selected from the device to perform what function, such as function code 03 is requirements from the device reads the register and return their contents; data segment contains from the device to perform the function of any additional information, check code used to test the correctness of a frame of information, from the device provides a validation message content to check the correctness of the method, which adopts CRC16 calibration rules。
From the machine response: if have normal response from the device, in response to the news is from the machine address code, code, data information code and CRC16 checksum code. Data information code include from equipment to collect data, such as register values or states. If an error occurs, we agreed is from the machine does not respond。
We specify the communication data format used in this instrument: the bit of each byte (1 start bit, 8 data bits, no parity, 1 stop bits).。
Data frame structure, namely message format：

Device address	Function code	Data segment	CRC16 check code
1 byte	1 byte	Byte N	2 byte

Device address: by a byte, in our system, only the use of 1~247, other address reservation. The address of each terminal device must be unique, only to be addressed to the terminal will respond to the corresponding query。
Function code: tells the address to the terminal to perform what function. The following table lists the series of instruments supported by the functional code, as well as their functions。

Function code	function
03H	Read the values of one or more registers
10H	Write the value of one or more registers

Data segment: data that contains the data required to perform a specific function or terminal response to a query. The contents of these data may be numeric, reference, or set values.。
Check code: CRC16 occupied two bytes, contains a 16 bit binary value value by the transmission equipment calculated.CRC and then attached to the data frame, receiving equipment calculates CRC value again when receiving data, then compares the value with the received CRC domain, if the two values are not equal, error occurs。
The process for generating a CRC16 is：
(1) Preset a 16 bit register to 0FFFFH (1), called the CRC register。
(2) The low byte of the first byte in the data frame of the 8 bit CRC register with the XOR operation, the result is stored back into the CRC register。
(3) The CRC register to the right one, the high fill to 0, the lowest detection and removal。
(4) If the least significant bit to 0: repeat the third step (a time shift); if the least significant bit to 1: CRC register and a preset fixed value (0A001H) is XORed with the。
(5) Repeat the third step and the fourth step until the 8 shift. This process is done with a full eight bit.。
(6) Repeat the second step to the fifth step to process the next eight bits, until all the byte processing ends。
(7)The value of the final CRC register is the value of the CRC16.。

Addendum to the two rating and the two value：
(1)Voltage is two times the value of the voltage, fixed 1 decimal places。
(2)The current is two times the current value, fixed 3 bit digital。
(3) Power is the two power value, fixed 0 bit digital。
(4) Fixed 3 bit number of power factor。
(5) Frequency fixed 2 bit digital。
