The basic difference is that Profibus utilises a hybrid media access technique using token bus and master slave protocols, whereas Foundation Fieldbus uses peer to peer communications where devices publish and subscribe to information. Profibus is made up of a family of protocols. PROFIBUS is a classic serial Fieldbus, and PROFINET is an industrial Ethernet protocol. PROFIBUS and PROFINET are both IEC standards created by the same organization: PROFIBUS and PROFINET International. Because of their common source, PROFIBUS and PROFINET do share some similarities.
2007-12-21 FOUNDATION fieldbus was originally intended as a replacement for the 4-20 mA standard, and today it coexists alongside other technologies such as Modbus, Profibus, and Industrial Ethernet. FOUNDATION fieldbus today enjoys a growing installed base in many heavy process applications such as refining, petrochemicals, power generation, and even food and beverage, pharmaceuticals, and nuclear What is PROFIBUS? PROFIBUS (Process Field Bus) is a fieldbus which is being used for high speed cyclic data communication in the world of automation. PROFIBUS has two different applications: Factory automation; Process automation; For each application PROFIBUS can use a different protocol. 2020-06-10 32 stations use profibus for distances upto 1200 meters, while 2 stations communicate at speed of 500 kbps for distances upto 400 meters. Low speed transmission supports higher distances while high speed transmission supports lower distances.
PROFINET networks are often designed as a star topology, or as several stars branching off a large ring backbone by using managed PROFINET switches. Profibus Modbus; Mode of operation: Operates in multi master mode using RS485.

Because of their common source, PROFIBUS and PROFINET do share some similarities. But generally, they are very different. Profibus ProfiBus (PROcess FIeld BUS) is a widely accepted international networking standard, commonly found in process control and in large assembly and material handling machines.

The device addresses must be entered into the Foundation fieldbus technology is mostly used in process industries, but nowadays it is being implemented in powerplants also.
Each fieldbus standard offers specific characteristics. PROFIBUS was introduced in the early 90s by PI. Currently, it is the leading fieldbus technology in terms of functionality and adoption. By 2019, there were over 62 million PROFIBUS nodes installed worldwide. Today, the trend continues with Industrial Ethernet standards, such as PROFINET. Se hela listan på controldesign.com

Its communications structure differs from PROFIBUS PA as it is peer-to-peer. This means instruments can communicate with each other, and can perform real-time control in the field as the data is deterministic. But on the operational side, we found a big difference. The PROFIBUS PA network uses the master-slave concept while FOUNDATION Fieldbus H1 goes peer to peer. This means that PROFIBUS PA field devices must wait for a master command.

However, it is also possible to have 4-wire fieldbus devices in the case of devices with a high current draw. Ethernet explained PROFIBUS (Process Field Bus) is a standard for fieldbus communication in automation technology and was first promoted in 1989 by BMBF (German department of education and research) and then used by Siemens.It should not be confused with the PROFINET standard for Industrial Ethernet.PROFIBUS is openly published as part of IEC 61158. Profibus uses master-slave communication, whereas Fieldbus uses peer-to-peer communication. Both use Manchester bus powered (MBP) and are perfectly usable with FISCO – a concept which has already proven itself in the field. Thus both technologies can be easily used in explosion-hazardous areas. Jede Technologie hat ihre Vorteile und Historie. Für Anwender stellt sich daher bei jeder Neuanlagen oder Sanierung von Altanlagen mit welcher Kommunikations Fieldbus is simply a means of communicating with input devices (sensors, switches, etc.) and output devices (valves, drives, indication lamps etc.) without the need to connect each individual device back to the controller (PLC, Industrial PC etc.).
