What is the difference between Profinet and Ethernet

The main differences between Profinet and Ethernet are as follows:

1. Profinet is an industrial network protocol, while Ethernet is a general-purpose network protocol.

2. Profinet supports real-time communication, while Ethernet does not.

3. Profinet supports multiple network topologies, while Ethernet only supports star topologies.

4. Profinet supports a wide range of network media, while Ethernet only supports twisted pair and fiber.

5. Profinet supports a wide range of network devices, while Ethernet only supports routers and switches.

In general, Profinet is an industrial communication protocol based on Ethernet technology, which is characterized by real-time, multi-manufacturer communication capabilities and optimized distributed intelligent automation systems. Ethernet, on the other hand, is a LAN specification that is applied to various scenarios, but does not support real-time communication.
