What type of network supports up to 99 devices at speeds up to 5 Mbps and utilizes coaxial or fiber cables?

The correct answer focuses on ControlNet, which is specifically designed to support high-speed, deterministic communication for industrial automation applications. This network type can connect up to 99 devices and operates at a speed of up to 5 Mbps. ControlNet utilizes both coaxial and fiber optic cables, providing flexibility in installation and networking topologies.

ControlNet is particularly suitable for applications requiring synchronized control and real-time data exchange between devices, making it ideal for critical control tasks in industrial settings. The combination of coaxial and fiber cables also enhances its robustness against electromagnetic interference, which is often encountered in industrial environments.

The other options reflect different network types with varying capabilities and characteristics. EtherNet/IP is built on standard Ethernet and generally has different scalability and speed characteristics. DeviceNet, on the other hand, primarily uses a different communication protocol and cabling and typically supports fewer devices at lower speeds. Remote I/O is more of a connectivity option rather than a standalone network type and does not specifically fit the defined parameters regarding speeds and device count.
