I’m currently working with an Itron SL7000 energy meter, which is connected to a Moxa NPort device via a serial COM port. The Moxa device converts the serial data to TCP and transmits it over port 4002 (IP: 10.100.121.101).

I’ve successfully tested the setup using the Ace Vision Web application, confirming that data is correctly transmitted from the source through the Moxa converter via HDLC tunneling over TCP. This indicates that the communication path from the energy meter to the Moxa device is      functioning properly.

I would like to ask about the implementation of the Auto‑Connect class in Gurux. Is it possible to simulate this class in the Gurux DLMS Simulator? My goal is to create a program that can simulate GPRS‑style sending and receiving, and I am specifically interested in the byte‑level packet behavior.

I also have a question regarding Protocol‑E communication. After the meter switches to the new baud rate, I am not receiving the expected ACK frame. Could you clarify what might cause this issue or what the correct sequence should be?

Thank you.

I need to simulate a DLMS meter using DLMS server application using C and GPRS communication. I have compiled the source code without any errors.

I tried to run DLMS client application(python) and DLMS server application(C) in two different boards. But the connection establishment is failing. Can you guide me on how to establish connection between client and server using GPRS?
Dynamic IP address is assigned on both boards.

Im getting following error when I tried to read the data from other board (meter simulator)

Questions about Gurux Net Media Component. Because we are able to receive data in Receive function

Hello,

I was able to connect to an ISKRA MT880 meter via GXDLMSDirector with parameters: -h 172.18.54.201 -p 4002 -c 1 -s 164 -a Low -P 12345678 -d Italy -w 1 -f 154 -t Verbose

If I try with C# code I am not able to connect. What am I missing?
Thanks
// Konfiguration für MT880 Zähler
string meterIpAddress = "172.18.54.201"; // Config 2 IP
int port = 4002;
int clientAddress = 1;
int serverAddress = 36;
string password = "12345678"; // Config 2 Passwort

Hi

I want to read push object list by using this code

GXDLMSPushSetup push = new GXDLMSPushSetup("0.0.25.9.0.255",3);

GXDLMSPushSetup clone = (GXDLMSPushSetup)push;

clone.GetPushValues(client, (List<object>)notify.Value);

foreach (KeyValueP<GXDLMSObject, GXDLMSCaptureObject> it in clone.PushObjectList)
{
int index = it.Value.AttributeIndex - 1;
Console.WriteLine(((IGXDLMSBase)it.Key).GetNames()[index] + ": " + it.Key.GetValues()[index]);
}

I have created 25,000 virtual meters using 'Gurux.DLMS.Simulator.net' but not able to read all meters simultaneously. it is randomly fails. success count is randomly changing from 5% to 40%. Majority meters are not replying any response and I am getting timeout error.
I have already tuned up all TCP connection settings & concurrent settings, so there is no configuration related issue at OS level.

Help me to solve this issue.

Dear Mikko,

Related to an itron (SL7000) meter's reading, it was observed a slight inaccuracy of conversion from hex to readings from programming (C#), as opposed to displaying values from Director.

Dear Mikko,

Hi, I faced a strange issue.
I used Director and was able to connect with the meter (itron SL7000).
I can even read the profile generic of the Load Profile 1.
All good.
The params are as follows:

-h xxx.xxx.xxx.xxx -p 7623 -c 1 -s 145 -a Low -P XXXXXXXX -w 1 -f 128

However, when I use the API library via .net coding, I am unable to read the profile generic with the following error:
"Gurux.DLMS.GXDLMSException: Access Error : Device reports scope of access violated."

Hi,

I have created 100 simulator in Gurux.DLMS.Simulator.Net project with start port 1000 to 1099, and it's working fine but randomly closes connection for some ports when I connect it from code or director tool.

Can you please suggest me the solution, as per my requirement it should always connect and response data as it is running in my local system.
