One application of Universal RIO is

Connections between controllers and I/O adapters More diagnostics for improved data collection and fault detection High speed data transfer between information systems Modems

Correct Answer:

Connections between controllers and I/O adapters

Explanation:

Universal RIO is about linking the PLC controller to remote I/O blocks through adapters, so the controller can manage I/O that’s located far from it. This setup lets you place I/O near the process equipment and still have a single, reliable path back to the controller, reducing wiring and simplifying topology. That’s why its primary application is connections between the controller and I/O adapters. The other options describe capabilities that aren’t the core role of Universal RIO—diagnostics and data transfer across information systems, or modem use—so they aren’t the primary purpose.
