Hi,

I'm exploring GURUX and all things involved in this community. But I'm also still learning DLMS/COSEM, more specifically the server model, and I have a doubt about the AA between a server and a client. So I'm doing this topic to request help =).

Whats the expected behavior of a class 15 object when a the same client, like public client, access a same logical device, like the manager, using 2 different communications ports of a physical device? (In each port, different contexts can be accordded)

I started my dot net simulator using this command
Gurux.DLMS.Simulator.Net.exe -p 1000 -x simulator_template.xml -N 10
this is what I am getting in my terminal

DLMS HDLC Logical Name simulator start in ports 1000-1009.

How to create a simulator of US?I tried it is default creating PC xml file

Is there any way to read multiple meters using gurux python library?According my analysis this example file is designed for one meter at a time.

I am trying to read the genus meter, It has got an optical port and a few onboard GPIO pins, and the voltage across these pins is 2.8Vdc. I'm unable to identify the serial pins for the communication. I've attached the photo for reference. Can someone please help me with the schematics?
Thanks in Advance.

Hello, I am using .NET library. The ReadRowsByRange method generates different bytes depending on where the code is executed. On my local work computer, one result is obtained, and in the docker container on linux (Ubuntu) there are other bytes.
