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)

Have I a way to differentiate the connections between a same client and server but in different physical networks at same time?

A answer to this question I'll help me a lot to understand how DLMS/COSEM works.

Bests Regards,

Hi Gabriel,

It's basically possible to establish multiple simultaneous connections, but usually, the meters allow only one connection at a time. The main reason for this is a lack of memory and CPU.

You need to create your own server for each communication port to make this possible.
