Which of the following is foundational to the function of an industrial network?

Node-based communication is foundational to the function of an industrial network because it allows multiple devices, or nodes, to communicate and share information effectively within a networked system. This type of communication facilitates distributed control, enabling various components of an industrial system—such as sensors, actuators, and controllers—to exchange data and collaborate in real-time.

Node-based communication is essential for ensuring that all parts of the industrial process can coordinate their actions, leading to improved efficiency, reliability, and scalability of the operations. By allowing each node to send and receive information, the network can operate cohesively, adapting to changes and ensuring better decision-making capabilities in automated environments.

In contrast, high latency would typically hinder performance and responsiveness in an industrial setting, while analog signal processing is less relevant in the context of modern digital networks that prioritize speed and accuracy. Single-point control does not leverage the collaborative functionality provided by node-based communication, limiting the network's operational effectiveness.
