EcoStruxure Machine Expert - TcpUdpCommunication, Library Guide

This document describes the library TcpUdpCommunication. The library provides the core functionality for implementing socket-based network communication protocols using TCP (Transmission Control Protocol) client and server, or UDP (User Datagram Protocol) including broadcast and multicast if supported by the platform. Only communication based on IPv4 via the Ethernet-ports of the controller is supported.
