VIII. Communication

This meter using Modbus RTU communication protocol, and it can run RS485 half-duplex

communication. Read function code is 0x03, write function code is 0x10, 16-bit CRC checking

is applied. The meter don’t feedback error message. The communication data type is 32 bit

integer data, true code stands for positive number, complemental code stands for negative

number, data rate is 0.001；for example, if the meter data received by host is 5000, then meter

data * rate = original data (5000*0.001=5.000). Therefore, when host writes meter, the data

should multiply by rate 1000 before it is sent to the meter.

Data Frame format：

Start bit Data bit Stop bit Check bit

NO181

Handling of abnormal communication：

If there is abnormal response put the function code on the top position 1. For example:

Host request the function code 0x03,and the response function

code from slave should be 0x83.

Error type code：

0x02---Data location error：the request data location from host computer exceeds the range of

the meter.

0x03---Data value error：the data value sent by host computer exceeds the data range of the

meter.

CRC check error, function code error, don’t return value.

1. Read Multiple Registers

For example: The host computer read AL1（1st alarm value 5.0）

Address code of AL1 is 0x0000，32bit（4 byte），seizes 2 data registers; hexadecimal

memory code of 5.0*1000=5000 is 0x00001388.
