By suri371994, 22 February, 2023 Forums DLMSDirector when I read the L1 Voltage in the GXDLMS Director, I wonder 2 times the read command packet was observed in Log File. Please mention the Comments below mention read command and Response from the Device. Note: In the Director, I was sent 1 time to Read the L1 Voltage.

Hi, You are reading two…
Hi,
You are reading two objects from the meter. At first the scaler and unit first and then the actual value.

As per your reply consider…
As per your reply consider 1st Request packet is Scaler Unit:-
7E //Start Frame
A0 //Des.Address
19 //Length
03 //server address
41 //client address
32 //Instance Value
3A BD //header CRC
E6 // Des. LSAP
E6 //Source LSAP
00 // LLC Quality Reserved for Future.
C0 01 C1
00 03 //OBIS Class Id
01 00 20 07 00 FF //( OBIS Code -- 1.0.32.07.0.255 )
03 //Attribute Id
00 //Instance
5D 9A //CRC ( FCS-16 )
7E //End Frame
2nd Request packet is the Actual value:-
7E //Start Frame
A0 //Des.Address
19 //Length
03 //server address
41 //client address
54 //Instance Value
0A BB //header CRC
E6 // Des. LSAP
E6 //Source LSAP
00 // LLC Quality Reserved for Future.
C0 01 C1
00 03 //OBIS Class Id
01 00 20 07 00 FF //( OBIS Code -- 1.0.32.07.0.255 )
02 //Attribute Id
00 //Instance
85 83 //CRC ( FCS-16 )
7E //End Frame
If I try to read straightaway actual value, I will get any error?
Note: I think Attribute Id will play key importance in the parameter reading, is it? (Scaler unit=3,Actual value=2)
Please mention the Instance of each data packet's importance.
