I am using a Holley DTS545 smart meter. How can I add objects manually with OBIS codes? And how can I know it's working?
I attached OBIS codes of my meter's objects.

Hi,

The document doesnt't tell the COSEM object type, but I believe that those are register objects.

Select device and select Edit and "Add object". Select Register as object type and set the OBIS code, e.g. 1.0.1.8.0.255.

Then try to read the value. If read succeeds, everything is ok. If it fails, you need to check the object type (it can also be data object) and OBIS code.

Hi,

You can see if it's working when you try to read it. The meter returns an error if object type or OBIS code is wrong.

Hi,
When I try to connect to my meter, it's loading as collecting objects and can't connect. I think my client address is correct. Should I do any configuration or settings on my meter?

Hi,

You must add one object manually before connecting to the meter, and then the objects are not collected when you establish the connection to the meter.

Hi,
Thank you for your help. Finally, I successfully got data from the meter. It is working great. Now, how can I get data in constant time? For example, I want to receive data from the meter once every 12 hours. smt like that.

Hi,
I downloaded Visual Studio and opened the DLMS client example, but I’m not sure how to adjust it to read data and save it. Could you please guide me on what to modify?

Hi,
I downloaded and opened Gurux.DLMS.Net in Visual Studio. Then I made a small change in the Program.cs file to log meter readings into a CSV file using this line:
File.AppendAllText("meter_log.csv", $"{DateTime.Now},{it.Key},{val}\n");

After building the project, I ran the executable from the Command Prompt like this:

Gurux.DLMS.Client.Example.Net.exe -S COM6 -b 9600 -c 10 -s 1 -r LN -a None -g "1.0.1.8.0.255:2"
The program connected to the meter and showed:

Connected:
Standard: DLMS
But then it gave this error:
Failed to receive reply from the device in given time.
System.Exception: Failed to receive reply from the device in given time.

After a few attempts, "This app can't run on your PC" error appeared on my computer

Hi,

One of your settings is different from what the meter expects. Select the meter in GXDLMSDirector, and you can see the correct command line arguments.
