In a function block, TCP/IP socket program logic is used to retrieve what type of data from an Ethernet serial-server?

The function block utilizing TCP/IP socket program logic is designed to retrieve stream data from an Ethernet serial server. Stream data is characterized by its continuous flow and is typically used in scenarios where data is being transmitted in real-time over a network, such as video or audio feeds. In the context of the Ethernet serial server, stream data is particularly relevant because TCP/IP protocols establish a connection-oriented communication channel that is well-suited for this type of continuous data exchange.

The nature of TCP/IP allows it to maintain the correct order and reliability in data transmission, which is essential for stream data that requires timely and sequential delivery. This is in contrast to packet data, which is generally discrete and may not maintain a constant flow. File data involves storage and retrieval mechanisms that serve different purposes than those typically associated with TCP/IP communication. Configuration data, while it can be transmitted over a network, usually pertains to the setup of devices rather than the real-time data flow that stream data entails.
