Надо отметить, что протоколы Industrial Ethernet в некоторых приложениях могут замещать или дополнять собой Уровни 3 и 4 (IP и TCP/UDP). Уровень
A protocol is a set of rules governing communications. Networking protocols specify what types of data can be sent, how each type of message will be identified, what actions can or must be taken by participants in the conversation, precisely where
They are suitable for fixed or dynamic flexible industrial automation applications and they offer excellent active and passive electrical interference resistance as required by Profinet system and Ethernet conforming with IEEE 802.3 Ethernet communications standards has also come a long way since that time, and many new components support communication without being tied to a traditional fieldbus. Would this move help plants ditch expensive managed switches and other shortcomings of popular fieldbuses? The 1788-EN2FFR linking device provides a gateway between an EtherNet/IP network and a single segment FOUNDATION Fieldbus H1 layer. The 1788-CN2FFR linking device provides a gateway between a ControlNet network and a FOUNDATION Fieldbus network. In this manual, both modules are referred to as the linking device. Note: For this item, a successor is available: Modbus TCP 750-362; EtherNet/IP TM 750-363 The 750-352 ETHERNET Fieldbus Coupler connects ETHERNET to the modular WAGO I/O System. The fieldbus coupler detects all connected I/O modules and creates a local process image.
It is a digital, two-way, multi-drop network positioned to replace proprietary networks that connect Programmable Logic Controllers (PLCs) of many big companies. The use of Ethernet for office LANs and consumer/residential computing has driven the cost down to a point that makes it practical for the plant floor — even with the emergence of industrially-adapted Ethernet hardware. It should be strongly emphasized that Ethernet is not a fieldbus. It is not even a complete protocol.

While Profibus can't operate on Ethernet, but for Profinet it can operate on Ethernet, but Profinet is not same with Profibus.
companies chose Ethernet as the future extension or replacement for “propri-etary” fieldbus technology, and associated standards were developed. Against this background, a company such as Beckhoff can expect to be asked: “Why yet another Ethernet approach?”The short, but concise answer is: “Ether-
Fieldbus requires one 9 Jun 2020 EtherCat is next on 7%, followed by Modbus-TCP on 5%, overtaking Ethernet Powerlink on 4%. Among the fieldbus contenders, Profibus is still 7 Jan 2019 Whereas today, the Fieldbus connections are more closely compared to the typical Ethernet connections where you can connect multiple field Compare the Ethernet and Fieldbus/Devicenet standards compared to a pre- defined 'post-box' where one layer would collect data from the previous layer.

Fieldbus is not easy to explain as it consists of different sets of protocols.
Anybus products enable industrial devices to communicate with any fieldbus or industrial Ethernet network — wired or wirelessly. DISCOVER.
Fieldbus Network VS 4-20mA network. 4-20 mA requires wire to each device from the host.
Modern EtherNet/IP (Ethernet Industrial Protocol) combines traditional […] EtherCAT (Ethernet for Control Automation Technology) is an Ethernet-based fieldbus system, invented by Beckhoff Automation. The protocol is standardized in IEC 61158 and is suitable for both hard and soft real-time computing requirements in automation technology.
