Not able to create two connection in parallel using libmodbus in Cpp

AZRAIQI-V

I tried to make two different server connection and it's working fine =)

AZRAIQI-V, did you able to connect with two clients to one server on the same port?

Or you created 2 servers, one on each port on the same controller and had 2 different clients connected to each of them?

Currently, I have 1 controller with 1 server on default port 502 and I'm not able to create two connection in parallel using libmodbus in Cpp

I'm trying to create two clients on the same PC to allow multi-threading

Only the second client that is connected to server is able to receive information

the first client to connect is returning error num=104, "connection reset by peer"

Thank you,

Split from Multiple clients connecting simultaneously to Modbus Server on Port 502.

Hello,

this isn't possible, only one connection of Client to Server's Port is possible. You need create different Port connection be able connect next Client.

Hi,

Can U describe server & clients in details with version.

Advanced controller uses multiplexing.
