Operating principle of a socket-connection

Before a socket can be opened resources for this type of connection must be made available to the controller. This is done by starting a session. The scope is specified here. The session can then be used for sending or receiving Ethernet telegrams. The implemented protocols are listed in Table 1.

Client-server relationship

A client is defined as a device that intends to establish a connection and initializes the active part of a connection setup. The server is initially passive and awaits a client query. The server becomes active once a client establishes a connection. Once a connection between client and server has been established, both devices can sending or receive data.
