Good evening,
I'm trying to understand how the Gurux builds the DLMS/COSEM message.
I'm debugging the project available on Github (https://github.com/Gurux/Gurux.DLMS.Net/tree/master/Gurux.DLMS.Client.E…) and I receive the error message in attachment and I can't debug the project. (I'm using VS2019)
I would like to know which Gurux's function gives me the message to send on my Smart Meter.

Thanks in advance.
Regards,
Alessia

Hello everyone,

  The first thing is to thank you in advance for this project and the help you provide.

 I'm trying writing a simple server to simulate a meter for emulate a Meter with DLMS Protocol. I am trying to write a simple server that push a PDU and add GLO cipher.

Can anyone help me out with a little example on how to add GLO cipher to my server with the translator structure?

We are trying to schedule a firmware activation in Star meters.
The system running our code currently runs in UTC+2 (Swedish summer time)
The meters runs in UTC+1 (Swedish normal time)
So we adjust the time to match the meters timezone like:
Ex.
var normalTime = firmwareInformation.ScheduleTime.Value.ToUniversalTime().AddSeconds(utcDiffSec);
var activateTime = new DateTimeOffset(normalTime.Year, normalTime.Month, normalTime.Day, normalTime.Hour, normalTime.Minute, normalTime.Second, normalTime.Millisecond, TimeSpan.FromSeconds(utcDiffSec));

Hi Mikko,

Is DLMS supports asynchronous communication in TCP/IP interface ?

Hi,

We are testing Secure meter using Serial and TCP interface respectively.
From the serial interface, we will get the response for the same request multiple times. Whereas from TCP interface we can get the response for the same request for the first time only.

For our testing purpose, we have created one intermediate environment which acts as a server and connected it to the meter via optical port. And we connect TCP from our testing application which acts as a client.

All request payloads are as follow :

Hello,

I am able to read EDMI MK 6 meter with .net code and read the parameter with Low authentication.

When I tried to read generic profile 1.0.94.91.4.255 with read by range and row it does n't work. So I tried with Read(it,2) and read(it,3) as suggested.

with data index =2, I got the result as {1, frequency}, {1, Voltage} and so on..
But in case of 3, I get list of objects. and value column in it return null.

Kindly help me to read this data from meter.

hello, i try to read Actaris SL7000. i use Gurux.DLMS.Net library. i take as reference ur example code.
when i try to send data there is no problem, i see transmitted data. but program stucks in Media.Receive Method included ReadDLMSPacket Method. i didnt change ReceiveParameters object because of i dont know how it work. Actually i can see that the meter send data but i dont read this data.
Where is the problem? How can i fix it?

Thanks...

Hello good day.

Thanks for the help.

I have two meters SL7000 and Landis + Gyr, the SL7000 connect successfully, change the cable at the Landis + Gyr and this not conect, the error is:

Hello, Gurux
I have try gurux.DLMS.Meter.Listener.Net . I am using Holley DTSD545 with gprs modem using dynamic addressing. So I have faced some problem and I show it below picture. I think I change AARQ, then I will be pass that error. Because, Holley DTSD545S meter AARQ is:
00 01 00 11 00 01 00 3C 60 3A 80 02 02 84 A1 09 06 07 60 85 74 05 08 01 01 8A 02 07 80 8B 07 60 85 74 05 08 02 01 AC 0A 80 08 30 30 30 30 30 30 30 30 BE 10 04 0E 01 00 00 00 06 5F 1F 04 00 FF FF FF 28 00
My question is how can I change AARQ? is possible or not?

Please help me?
