Profinet is an Ethernet-based protocol that provides greater transmission speeds and flexibility compared against Profibus. The Profinet cable employs the standard Ethernet cable wiring, plus shielding and other improvements to better withstand ...

Modbus TCP and ProfiNet are two very different protocols. What they have in common is that they use the same hardware but after that they differ. The Modbus TCP stack is very small and simple and is only good for transferring basic PLC types. The byte and word order is a problem for 32 bit values because it isn’t really defined in the specification.

PROFINET is a popular fieldbus topology built on the industry standard Ethernet infrastructure. The PROFINET topology is used with the Siemens control system, and the encoder can be configured using the Siemens TIA portal.

PROFINET is an industrial protocol that supports real-time data exchange between sensors, controllers, computers, and other devices found in industrial networks. It can be configured in complex manners to support the most efficient flow of data ...

One criteria will be openness. - Modbus/TCP is documented publically - ProfiNet is only visible for members of the Profibus Nutzer Organisation - Ethernet/IP don't know if Rockwell opens their documentation In most cases you will have to use the protocol your PLC can speak.

PROFINET networks are primarily deployed using line topology, which reduces the amount of cable needed, although tree and star topologies are also supported.

I have been reading a lot of thing about industrial ethernet. I have doubt: I understood that HSE and Ethernet/IP operate on the link layers and physics that already exist in the ethernet 802.3 and Profinet doesn't only work with TCP and UDP, he has a direct channel with the layer link.

They're intended to replace things like Sercos, not Modbus. EtherCAT is another specialised network, aimed at replacing things like CANOpen. EthernetIP and ProfiNet aren't so much protocols as they are brand names for collections of protocols intended to address a variety of niches.

> Dear Mr. Vahid: While Profibus DP and Profinet are excellent fieldbus technologies, they have not been designed for closed loop process control. They may be fast, and in actual usage they MAY be fast enough, but there is no clocking structure within the protocol to synchronize measurements with the demands of a sampled data controller.

Since these protocols have different TCP Ports assigned 1 Ethernet interface can handle all of them at the same time.<pre> lehrig@nb5lehrig:~/Downloads> grep -i profinet /etc/services profinet-rt 34962/tcp # PROFInet RT Unicast [Peter_Wenzel] profinet-rt 34962/udp # PROFInet RT Unicast [Peter_Wenzel] profinet-rtm 34963/tcp # PROFInet RT Multicast [Peter_Wenzel] profinet-rtm 34963/udp # PROFInet RT Multicast [Peter_Wenzel] profinet-cm 34964/tcp # PROFInet Context Manager [Peter_Wenzel] profinet-cm 34964/udp # PROFInet Context Manager [Peter_Wenzel] lehrig@nb5lehrig:~/Downloads> grep -i dnp /etc

The first major change to the series is an update in the PROFINET communication protocol that allows sensors to transmit more information.

I have a Lenze servo controlled by an Inverter Drive 8400 TopLine C. I have profinet communication between the Inverter and a Siemens S7-1500 PLC. I don't know how to setup/view the Profinet IO using the Siemens TIA Portal V13.

The Profinet comittee has apparently decided that they don't want to implement it by tunneling the regular Profibus protocol inside TCP/IP packets (as some other people are doing). They want to use COM/DCOM because they see it as a means of connecting to the highest enterprise levels.

We have Siemens S7 v9.0 DCS system. Is this possible to transmit Profinet of S7 9.0 over a Radio Link using Access Point/Outdoor CPE of UBIQUITI/TP-Link? (for cheaper solution) However, there are access points available in Siemens which is used for wireless Profinet network.

Industrial Ethernet and PROFINET are variations of the original Ethernet standard. Most large companies tend to pick one of the two protocols and stick with it. Still, some PLCs allow for running a controller as a scanner or host with either protocol, sometimes even simultaneously, since the physical port is the same.
https://control.com/forums/threads/using-both-modbus-tcp-and-profinet-on-the-same-ethernet-cable.49542/
Yes, you can use the same Ethernet connection for both PROFINET and Modbus/TCP devices. Our Ethernet gateways support multiple protocols simultaneously, which include both PROFINET and Modbus/TCP, and there are no issues with communicating using both at the same time.

Profinet is an industrial protocol typically using ethernet connections. It is necessary to remove the RJ45 connector and hardwire the twisted pair wiring directly to PCB-mounted terminal blocks in some tight spaces.

In order to avoid any conversational quagmires with respect to Industrial Ethernet as a whole, let us assume that the automation industry has a real need for Ethernet technologies visa-vi TCP/IP etc. What I see in ProfiNet is a rehashing of 5 year old technologies (at best) in a slightly different form.

The power-feed module uses the industrial protocol ProfiNet to transfer the monitoring data. By making use of the ProfiNet protocol, Phoenix Contact is making use of an industry standard to cyclicly transmit data to a control platform.

There is at least one solution available; an AnyBus-X gateway can look like a ProfiNet I/O device to the S7 PLC and acts as a scanner to the Point I/O.
