DLMS protocol for LZQJ-DLMS-E-1.25

[Jellyfish]

Hi,

Eee... Not quite understand about the Class ID and Attribute ID, how can we find the 2 IDs based on the element that we want and from this 2 IDs, how can form the request code that need to send for the DLMS meter ? How we can decode the code that replied from the DLMS meter ?

hi,

   For all of your queries, the answer is very simple you need to study the DLMS Specification. Study all DLMS Color books (BLUE, GREEN, YELLOW and WHITE), in these books they have defined the structure of commands.

ALL THE BEST.

Hi guy,

I'm a fresh man for DLMS. I also try to read some value in my meter. My step: 

Step 1: send SNRM request and handle UA response

I'm not sure about step 3, so I cant read the value 1.8.0. The above code in step is take from the log file of Gurux. 

Who can give a full tutorial about steps in order to read the value on my meter?

Big thanks for yr time!

Hi,

I am also working on meter which is DLMS compliance. I am using dlms dll to communicate with meter...but i m not getting any output

[Clecio]

Hi for all,

Do you have an example VI that shows the communication?

Thank you.

Hi Ramesh,

Can you please share LabVIEW  vi example to communicate with meter using DLMS protocol.
