What does "System Integration" refer to in industrial automation?

"System Integration" in the context of industrial automation refers to the process of combining various subsystems into a single functional system. This approach ensures that different components, which may operate independently on their own, can work together seamlessly to achieve a common set of objectives. Effective system integration leads to improved efficiency, enhanced communication, and better overall control of processes within the industrial environment.

This process often involves configuring hardware and software, ensuring compatibility, and establishing communication protocols among the subsystems. The goal is to create a cohesive system where parameters can be monitored and controlled effectively, resulting in optimized operations.

The other options focus on aspects that do not accurately define system integration. For instance, splitting subsystems into separate operations goes against the idea of integration. Documenting specifications and conducting testing and validation are also important but represent different stages of the system development lifecycle rather than the act of integration itself.
