Hi team, Can anyone tell me, or guide me to, the maximum allowed number of UDP connections (with UDP_SOCKET) on a 1152 or 2152 controller? I can’t seem to find a maximum… Thanks.
Hello, you mean maximum number of concurrent connections? You have one UDP Socket that is sending data on XXX UDP_Send FBs(to various targets) And one UDP_Recieve FB listening on the Port and returning Data + Source. UDP does not maintain sessions like TCP. Or do you want to know how many instances of the UDP_Socket FB you can create to listen on different multiple ports? Basically the number of all sockets is limited by the Linux OS its 32768 minus all the sockets the OS or PLCnext Runtime already uses. But you also have a limit of the Project Size limiting the amount of UDP kind regards, Oliver
