5.3.2 Communication connection
5.3.3 Communication protocol
DF433 Multifunction transducer communicates with master device with MODBUS protocol and RTU mode.
MODBUS protocol use master/slave responding connection (half duplex) on the same Communication line.
After signal from host computer addressing of the only one terminal device (slave computer), the terminal device
sends answering signal and transmit to host computer.
MODBUS protocol can only permitted to used between host computer (PC, PLC etc.) and terminal device,
thus to prohibit the data exchange between independent terminal devices. In this way, every terminal device
does not occupy Communication line in their initialization, only responding to the enquiry signal from host.
(1) Transmission mode
The information transmit in asynchronous mode in bytes, the Communication information transmitting
between the host computer and the slave computer is the 10 bits format, including one initial bit, 8 data bit (Firstly
Transmitting the least effective bit), with even parity bit(it is configurable), 1 stop bit.
(2)Data frame format
Address code Function code Data area CRC check code
1 byte 1 byte n byte 2 byte
Address code: address code is located at beginning of frame, composed of one byte (8 bit binary system
code), decimal system is 0~255, in the ACR meters, just 1~247 is used, other address is Reserved. These bits
indicate terminal device address specified by users, this device will receive the connecting host computer data.
Every terminal device has only one address, only the addressing terminal respond to enquiry including this address.
When terminal is transmitting one responding, the responding slave address data tell host computer that which
terminal is it.
Function code: function code tells the target terminal to execute what function. Below table lists function
code used in this series meters, and their meaning and function.

03H Read data register Obtain current binary system value of one or multiple register
10H Preset multi-register Set binary system value into a series of multi-register
Data area: data area includes the data needed by terminal for executing specific function, or the collected data
when terminal is responding enquiry. Content of these data could be value, reference address or setting value. For
example: The function code tell terminal to Read one register, the data area need to specify the starting register
and Read how many data, the built-in address and data have different content depending on type and slave
computer.
CRC check code: Error check (CRC) code includes 2 bytes, including one 16 bit binary system value. CRC
value is calculated by transmission device, and then attached to the data frame, the receiving device, while
receiving, it calculates the CRC value again, then compare it with the receiving CRC domain value, if these two
values are not equal, it an error occurs.
Following is the process of forming one CRC:
1. Preset one 16 bit register as 0FFFFH (All-1), called as CRC register.
2. 8 bit of data frame first byte and low byte of CRC register carry out exclusive or operation, then save its
result back to CRC register.
3. Right shift CRC register for one bit, the most significant bit is filled with 0, the least significant bit is shifted
out and tested.
4. If the least significant bit is 0, repeat the third step (next shift); if the least significant bit is 1, CRC register
and preset fixed value specified (0A001H) carry out exclusive or operation.
5. Repeat the third step and the fourth step until shift for 8 times, the complete 8 bit is done.
6. Repeat the second step to the fifth step to treat next 8 bit until all the byte is treated.
7. The CRC register final value is CRC value. Besides, there is another CRC calculation method by preset
table, its main feature is fast calculating speed, but large saving space is needed, please refer to related data.
5.3.4 Expatiating for communication applicable format
(1)Function 03H: read register
This function allow user to obtain data and parameters collected and recorded by equipment. Data amount of
once requested by host computer have no limit, but the address should be in range.
Following example is one basic data read from 01 slave (each address in data frame occupies 2 bytes). The
collected data is the total electric energy E (4 bytes), other address is 00H.
