I launched gurux.dlms.python/Gurux.DLMS.Client.Example.python
I have an Itron Actaris SL7000 meter connected via RS485 via an RS485-Net converter.
I connected, I read the registers, but the reading takes place from 8-12 attempts:
python3 main.py -r ln -c 1 -s 17 -l 1 -h xx.xx.xx.xx -p xxxx -a Low -P ABCDEFGH -g "1.1.91.7.0.255:1; 1.1.91.7.0.255:2; 1.1.91.7.0.255:3; 0.0.40.0.0.255:1; 0.0.40.0.0.255:4; 1.1.92.7.0.255:1; 1.1.92.7.0.255:2; 1.1.92.7.0.255:3" -d DLMS -t Info -C None

What am I doing wrong that many times there is a connection attempt:
Data send failed. Try to resend 1/3
And second question:
If I not write "-l 1" - does not connection, and "ServerAddress: 0x11".
If I write "-l 1" - there is a connection, and "ServerAddress: 0x91"!!!
Why?

Hi,
Hi,
You are not doing anything wrong. Data send failed. Try to resend 1/3 is coming because your PC is so fast and the meter can't handle all incoming requests. You can use -o output.xml to save association view to the XML file. It makes reading faster.
Your meter is using also the Logical device address and if you don't give it with -l parameter, the meter doesn't reply, because the server address is wrong.
Meters are using different server addresses and you can even change it. Problem here is that the meter doesn't answer anything if the meter address is wrong.

So the script sends a request
Thanks for the answer.
So the script sends a request several times until the counter responds. And he answers, the data is received. But in DLMS.Director, the connection is formed instantly and reading is also instantaneous and without errors. In DLMS.Director everything is much faster!
With counter addressing, I got it!
Hi,
Hi,
There might be re-sending in GXDLMSDirector. You can check them from the log file. It's common that meters don't reply to all requests. It depends on the communication channel and if the communication channel is bad, this is happening quite often.

I started Client.Example in C
I started Client.Example in C ++ and saw that it uses the method GetAssociationView and it reads the association view of all objects even I read one/two of them! I guess that this is the register read latency. While the counter transfers all objects, the client cannot read the register value. Therefore, this error and delay exists.
And your advice with the -o
And your advice with the -o output.xml parameter helped a lot. Now the counter responds immediately and there is no delay.
Thank you, Mr Kurumi.
Hi,
Hi,
I'm glad that the saving association view helped.
