Though, Modbus can run on Ethernet, include the multiple masters. While Profibus can't operate on Ethernet, but for Profinet it can operate on Ethernet, but Profinet is not same with Profibus. Profibus is a real sensor or actor of the fieldbus. Really what we have been seeing is Ethernet taking the place of old digital communication networks; control network (level 2 in the Purdue reference model) and remote-I/O (H2 fieldbus at level 1-1/2 in the reference model), that is, where legacy protocols (often proprietary) have initially paved the way. One of the five real-time Ethernet fieldbus standards has achieved a tipping point of acceptance. Cutting through all the marketing clutter, it becomes clear that EtherCAT offers both superior performance and market acceptance. Its performance is an order of magnitude better than Ethernet IP and Powerlink.
As you know, serial communications allowed only two devices to communicate. Whereas today, the Fieldbus connections are more closely compared to the typical Ethernet connections where you can connect multiple field devices to a single connection point that would then connect to the This video explains one of the most dramatic evolutions in the Industrial Automation Industry: The transition from 4-20 mA to digital fieldbuses. Learn about With fieldbus and Ethernet system you increase the efficiency in extending plants with distributed control logic. You can clearly structure the systems or connect several networks to each other. The widest range of automation architectures can be implemented using the appropriate components. Profinet cables are industrial Ethernet cables, sometimes referred to as industrial Cat5 or two-pair Cat5, for the cabling of industrial fieldbus systems with the globally accepted TCP/IP protocol.

However, it is also possible to have 4-wire fieldbus devices in the case of devices with a high current draw. Ethernet explained “One significant difference between fieldbus networks and Ethernet networks is speed, as in most cases Ethernet networks will be faster despite the additional overhead,” explains Ian Verhappen, senior project manager, automation, CIMA+.

Indeed H1 fieldbus is taking the place of traditionally hardwired 4-20 mA and on/off signals for sensors and actuators.

Since modern machines and systems must perform increasingly complex tasks, Basics of the buses. A group of Wiki-style web pages presented by Kunbus covers the basic history, characteristics and applications of the major fieldbuses and Ethernet-based protocols and technologies, including Profibus, Profinet, Ethernet/IP, Foundation fieldbus, Modbus TCP, DeviceNet, CC-Link, CANopen, EtherCAT, Ethernet Powerlink, AS-i, BACnet and others. A key differentiator is determinism, with fieldbus networks claiming guaranteed response times that Ethernet can’t deliver. Distance is another factor.

A fieldbus trunk or segment – either FOUNDATION fieldbus H1 or PROFIBUS PA – is a single twisted pair wire carrying a digital signal and DC power.

Supporters claim device and fieldbus networks guarantee a response time, while Ethernet can’t. This differentiator is very essential for certain applications, such as position-dependent operations. The economics of adopting Ethernet as a fieldbus are compelling because Ethernet components offer dramatically lower costs and are universally available.
