Profinet implements the interfacing to peripherals. [1] [2] It defines the communication with field connected peripheral devices.Its basis is a cascading real-time concept. Profinet defines the entire data exchange between controllers (called "IO-Controllers") and the devices (called "IO-Devices"), as well as parameter setting and diagnosi
The first version of Profisafe was released as early as 1998. [4] A second version in 2005 also enabled use via the Ethernet-based Profinet. According to the PROFIBUS Nutzerorganisation e.V., by 2023 a total of almost 21,7 million devices with Profisafe will be placed on the market by the various manufacturers, and a further 2.8 million devices will be added each year.

The connector commonly used for twisted-pair Ethernet is a non-keyed 8P8C connector, quite distinct from that used for RJ45S. The new ARJ45 interface, however, is a plug and jack allowing higher transmission rates, and the jack can, optionally, be backward-compatible with the common 8P8C plugs of Gigabit Ethernet and earlier standards.
The network controller implements the electronic circuitry required to communicate using a specific physical layer and data link layer standard such as Ethernet or Wi-Fi. [a] This provides a base for a full network protocol stack, allowing communication among computers on the same local area network (LAN) and large-scale network communications through routable protocols, such as Internet ...
The physical-layer specifications of the Ethernet family of computer network standards are published by the Institute of Electrical and Electronics Engineers (IEEE), which defines the electrical or optical properties and the transfer speed of the physical connection between a device and the network or between network devices.
Ethernet over USB is the use of a USB link as a part of an Ethernet network, resulting in an Ethernet connection over USB (instead of e.g. PCI or PCIe).. USB over Ethernet (also called USB over Network or USB over IP) is a system to share USB-based devices over Ethernet, Wi-Fi, or the Internet, allowing access to devices over a network.
