EES-401 Series Ultrasonic Energy Meter

Revision: 3.0.1

Page 76 of 90

Pay attention to the data storage order of the above example. Using C language to explain the data, pointers can be
used directly to input the required data in the corresponding variable address, the low byte will be put at the
beginning, such as the above example 1.2345678 m/s, 3F 9E 06 51 data stored in order as 06 51 3F 9E .

Example 2. In RTU mode, read the positive accumulation (m3) of the meter with address 1 (0x01) in m3, that is,
read the data of the three registers of register address 0008, 0009, 000A, the read command is as follows:

0x01

0x03

0x00 0x08

0x00 0x03

0x84 0x09

Meter Address Function Code Register First Address Number of Register CRC Check Code

The data returned by the meter is (assuming the current positive cumulative amount = 2.46m3):

0x01

0x03

0x06 0x00 0xF6 0x00 0x00 0xFF 0xFE

0x29 0x10

Meter Address Function Code Number of Data Bytes Data(246*10-2)

CRC Check Code

Among them, the four bytes of 00 00 00 F6 are 246 hexadecimal, that is, directly convert the hexadecimal data
into decimal.

The two bytes of FF FE are 10 to the power of -2. As shown in the table below:
