Directly connected to TLS_SOCKET.BIND_PORT / UDP_SOCKET.BIND_PORT.Defines the local port number associated with the IP address of the selectedEthernet adapter (BIND_IP input) to which the created socket is bound(necessary for setting up TCP servers). The selected port number is used by theTCP server for incoming data. If the value is 0 or the input is not connected, thestack assigns a temporary port.By using more than one MB_TCP_Server on one device, this parameter must bedifferent.For details refer to the documentation of the firmware function blocksTLS_SOCKET and UDP_SOCKET in the PLCnext Engineer help.
