What is the difference between Profinet cable and Profibus cable

Profinet cable and Profibus cable have significant differences in nature, function, transmission rate, transmission distance and so on.
Properties: Profinet is a new generation of automation bus standard based on industrial Ethernet technology, and Profibus is a field bus standard used in automation technology.
Role: Profinet provides a complete network solution for automated communications, including real-time Ethernet, motion control, distributed automation, fail-safe and network security, and other hot topics in the current automation field. Profibus is mainly used for non-deterministic communication between the master station and deterministic communication between the master station and its remote slave station.
Transmission rate and distance: The Profibus bus cable can support high-speed transmission, usually up to 12Mbps, and its transmission distance can reach thousands of meters. The Profinet protocol transmits data through Ethernet hardware and TCP/IP protocol stack, which can achieve faster data transmission speed and higher communication efficiency.
Cable characteristics: Profinet cable has excellent anti-interference performance, and its sheath also has flame retardant, oil proof, mechanical resistance, wear resistance, oil resistance, acid and alkali resistance, hydrolysis resistance, corrosion resistance and UV protection characteristics, suitable for use in complex and harsh environments. Profibus cable has better anti-interference and anti-interference ability, and adopts twisted pair structure, which can flexibly adapt to various network topologies.
In general, Profinet cables and Profibus cables have their own unique advantages and application scenarios in the field of industrial automation, and the specific choice depends on the specific application needs and environmental conditions.
