MODBUS RTU

The hardware version number of this document is V2.0; the software version number is V5.9 and above. This document describes the MODBUS RTU interface in details and the target object is a software programmer.

MODBUS Command Structure
Data format description in this document; Binary display, suffix B, for example: 10001B – decimal display, without any prefix or suffix, for example: 256 Hexadecimal display, prefix 0x, for example: 0x2A ASCII character or ASCII string display, for example: “YL0114010022”

Command Structure
The MODBUS application protocol defines the Simple Protocol Data Unit (PDU), which is independent of the underlying communication layer.

MODBUS protocol mapping on a specific bus or network introduces additional fields of protocol data units. The client that initiates the MODBUS exchange creates the MODBUS PDU, and then adds the domain to establish the correct communication PDU.

On the MODBUS serial line, the address domain contains only the slave instrument address. Tips: The device address range is 1…247 Set the device address of the slave in the address field of the request frame sent by the host. When the slave instrument responds, it places its instrument address in the address area of the response frame so that the master station communicates with the correct slave Function codes indicate the type of operation performed by the server. CRC domain is the result of the “ redundancy check” calculation, which is executed according to the information content.

MODBUS RTU Transmission Mode

When the instrument uses RTU (Remote Terminal Unit) mode for MODBUS serial communication, each 8-bit byte of information contains two 4-bit hexadecimal characters. The main advantages of this mode are greater character density and better data throughput than the ASCII mode with the same baud rate. Each message must be transmitted as a continuous string.

The format of each byte in RTU mode (11 bits):

Coding system: 8-bit binary

Each 8-bit byte in a message contains two 4-bit hexadecimal characters (0-9, A-F)
Bits in each byte: 1 starting bit
8 data bits, the first minimum valid bits without parity check bits

2 stop bits
Baud rate: 9600 BPS
How characters are transmitted serially:

Each character or byte is sent in this order (from left to right) the least significant bit (LSB)… Maximum Significant Bit (MSB)

Start bit

Stop bit

Check Domain Structure: Cyclic Redundancy Check (CRC16)

Structure description:

Slave Instrument	Function Code	Data	CRC
Address	1 byte	0…252 byte	2 byte
			CRC Low byte \| CRC High byte

Fig.4 : RTU Information Structure
The maximum frame size of MODBUS is 256 bytes
MODBUS RTU Information Frame
In RTU mode, message frames are distinguished by idle intervals of at least 3.5 character times, which are called t3.5 in subsequent sections.

Starting	Address	Function code	Data	CRC check	End
≥ 3.5 characters	8 bit	8 bit	Nx8 bit	16 bit	≥ 3.5 characters

Fig.5 : RTU Message Frame
The entire message frame must be sent in a continuous character stream. When the pause time interval between two characters exceeds 1.5 characters, the information frame is considered incomplete and the receiver does not receive the information frame.

MODBUS RTU CRC Check
The RTU mode contains an error-detection domain based on a cyclic redundancy check (CRC) algorithm that performs on all message contents. The CRC domain checks the contents of the entire message and performs this check regard-less of whether the message has a random parity check. The CRC domain contains a 16-bit value consisting of two 8-bit bytes. CRC16 check is adopted. Low bytes precede, high bytes precede.

Implementation of MODBUS RTU in Instrument

According to the official MODBUS definition, the command starts with a 3.5 character interval triggering command, and the end of the command is also represented by a 3.5 character interval. The device address and MODBUS function code have 8 bits. The data string contains n*8 bits, and the data string contains the starting address of the register and the number of read/write registers. CRC check is 16 bits.

Instrument MODBUS RTU function code

The instrument only uses two MODBUS function codes:

0x03: Read-and-hold register

0x10: Write multiple registers

MODBUS Function Code 0x03: Read-and-hold Register
This function code is used to read the continuous block content of the holding register of the remote device. Request the PDU to specify the start register address and the number of registers. Address registers from zero. Therefore, the addressing register 1-16 is 0-15. The register data in the response information is packaged in two bytes per register. For each register, the first byte contains high bits and the second byte contains low bits.

Request:

Function Code	1 byte	0x03
Start Address	2 byte	0x0000 0xfffff
Read Register Number	2 byte	1…125

Data Format in Instrument

Floating Point

Definition: Floating point, conforming to IEEE 754 (single precision)

Description	Symbol	Index	Mantissa	SUM
Bit	3	30…23	22…0	22…0
Index Deviation	127

Figure 14 : Floating Point Single Precision Definition (4 bytes, 2 MODBUS Registers)

Example: Compile decimal 17.625 to binary

Step 1:

Converting 17.625 in decimal form to a floating-point number in binary form, first finding the binary representation of the integer part 17decimal= 16 + 1 = 1×24 + 0×23 + 0×22 + 0×21 + 1×20

The binary representation of integer part 17 is 10001B then the binary representation of decimal part is obtained 0.625= 0.5 + 0.125 = 1×2−1 + 0×2−2 + 1×2−3
The binary representation of decimal part 0.625 is 0.101B. So the binary floating point number of 17.625 in decimal form is 10001.101B

Step 2:
Shift to find the exponent. Move 10001.101B to the left until there is only one decimal point, resulting in 1.0001101B, and 10001.101B = 1.0001101 B× 24 . So the exponential part is 4, plus 127, it becomes 131, and its binary representation is 10000011B.

Step 3:
Calculate the tail number After removing 1 before the decimal point of 1.0001101B, the final number is 0001101B (because before the decimal point must be 1, so IEEE stipulates that only the decimal point behind can be recorded). For the important explanation of 23-bit mantissa, the first (i.e. hidden bit) is not compiled. Hidden bits are bits on the left side of the separator, which are usually set to 1 and suppressed.

Step 4:
Symbol bit definition The sign bit of positive number is 0, and the sign bit of negative number is 1, so the sign bit of 17.625 is 0.

Step 5:
Convert to floating point number 1 bit symbol + 8 bit index + 23-bit mantissa 0 10000011 00011010000000000000000B (the hexadecimal system is shown as 0 x418d0000 )

Reference code:

If the compiler used by the user has a library function that implements this function, the library function can be called directly, for example, using C language, then you can directly call the C library function memcpy to obtain an integer representation of the floating-point storage format in memory.
For example: float float data; // converted floating point number void* out data; memcpy(outdata,&floatdata,4); Suppose float data = 17.625
If it is a small-end storage mode, after executing the above statement, the data stored in the address unit out data is 0x00.
Out data + 1 stores data as 0x00
address unit (out data + 2) stores data as 0x8D
address unit (out data + 3) stores data as 0x41
If it is large-end storage mode, after executing the above statement, the data stored in out data of address unit is 0x41 Out data + 1 stores data as 0x8D
address unit (out data + 2) stores data as 0x00
address unit (out data + 3) stores data as 0x00
If the compiler used by the user does not implement the library function of this function, the following functions can be used to achieve this function:
void memcpy(void *dest, void *src,int n)
{
char *pd = (char *)dest; char *ps = (char *)src; for(int i=0;i<n;i++) *pd++ = *ps++;
}
And then make a call to the above memcpy(outdata,&floatdata,4);

Example: Compile binary floating-point number 0100 0010 0111 1011 0110 0110 0110 10B to decimal number

Step 1: Divide the binary floating-point number 0100 0010 0111 1011 0110 0110 0110B into symbol bit, exponential bit and mantissa bit.
0 10000100 11110110110011001100110B
1-bit sign + 8-bit index + 23-bit tail sign bit S: 0 denotes positive number
Index position E: 10000100B =1×27+0×26+0×25+0×24 + 0 × 23+1×22+0×21+0×20
=128+0+0+0+0+4+0+0=132
Mantissa bits M: 11110110110011001100110B =8087142

Step 2: Calculate the decimal number
D = (−1)S×(1.0 + M/223)×2E−127
= (−1)0×(1.0 + 8087142/223)×2132−127
= 1×1.964062452316284×32
= 62.85

Reference Code:
float float TO decimal (long int byte0, long int byte1, long int byte2, long int byte3)
{ long int realbyte0,realbyte1,realbyte2,realbyte3; char S;
long int E,M;
float D;
realbyte0 = byte3; realbyte1 = byte2; realbyte2 = byte1; realbyte3 = byte0;
if((realbyte0&0x80)==0)
{ S = 0;//positive number }
else { S = 1;//negative number }
E = ((realbyte0<<1)|(realbyte1&0x80)>>7)-127;
M = ((realbyte1&0x7f) << 16) | (realbyte2<< 8)| realbyte3;
D = pow(-1,S)*(1.0 + M/pow(2,23))* pow(2,E);
return D; }
Function description: parameters byte0, byte1, byte2, byte3 represent 4 bytes of binary floating point number. The decimal number converted from the return value. For example, the user sends the command to get the temperature value and dissolved oxygen value to the probe. The4 bytes representing the temperature value in the received response frame are 0x00, 0x00, 0x8d and 0x41. Then the user can get the decimal number of the corresponding temperature value through the following call statement.
That is temperature = 17.625.
float temperature = float TO decimal ( 0x00, 0x00, 0x8d, 0x41)
