Q06 : How to read HART device CMD 3 data with standard format by 

Modbus ? 

A06:  

(1) When adding a new HART device to HRT-710, the “Default CMD(3)” will be added 

automatically. The Modbus start address and length of the “Default CMD(3)” will show in 
the “Cmd In address” and “Cmd In size” field like Figure 6-1. In the example they are 
1236 (For MB Addr = 618 = 0x026A) and 26 (byte count=26 => word count=13). 

 

Figure 6-1 “Default CMD(3)” of HART device in HRT-710 

(2) The below demo will use the free MB/RTU tool provided by ICP DAS to show HART 

command 1 data. (Download from   

http://ftp.icpdas.com.tw/pub/cd/8000cd/napdos/modbus/modbus_utility/

)  

(3) Run “MB/RTU” tool. Set the com port settings the same with HART-710 (Baud Rate / 

Data Bits / Stop Bits / Parity) and then click “Open” button to connect to HRT-710 like 
Figure 6-2. 

(4) Input “01 04 02 6A 00 0D” in “Command” field and click “Send Command” button to send 

the Modbus command. The HART command 3 data will be received in “Responses” 
field => “01 04 1A 00 00 A1 41 22 01 3E 0C C5 C5 20 B0 B6 41 C0 78 42 39 91 C9 00 
C5 00 00 00 00 E5 B0” like Figure 6-2.
