==========================
Profibus and Profinet are industrial communications protocols used extensively by Siemens control systems.
While they may sound similar, don't let the names fool you. Profibus and Profinet are very different protocols that use different cables and connectors.
Let's take a look at these protocols and learn how they differ from one another.

[@melquiadesdelgadoramirez680]

Using one of both depends on the application. In the case of processes involving discrete variables, motion control and fast response applications Profinet is most likely to be used. Profibus better fits in processes like mixing products, temperature control, and reduced speed applications (compared to Profinet).

[@DeKempster]

Not true, Profinet is the way, profibus is old fashioned, cannot carry tcp/ip traffic. for these process speed is indeed not the issue but profinet provides much more than speed alone.

[@yimingcheng5097]

The frequency inverter symbol used in this video is actually Siemens Sinamics V20 which doesn't support Profibus or Profinet. It would be better to use the symbol of SINAMICS G120 or G120C instead.

[@arturw7682]

Profibus physical layer is RS485 , last and first device on the bus has to have termiation. Addressing starts from 0 up to 125, 126,127 are special addresses. Other media (like fiber optic cables can also be used)

[@alikhanzulkashov4438]

You are right, fiber optic is usually used to compensate for data transmission speed by means of converting one transmission media ( copper cable) into another (fiber optic) by optic link module or some other media converter

As practice shows, daisy chaining through pass port is not best for permanent connection. What it is mostly used is for connecting your programming device.

[@ardentdfender4116]

So very well explained as is every video. It must be a checklist initiative on the creative team that every video must be well and clearly explained that any new person to automations will understand. Just so well done. Question though: Is ProfiNet only used with Siemens PLC Systems? Is there some inherent value with all the shielding on the ProfiNet cab,e?

[@scottsommer5450]

There are other systems besides Siemens that use ProfiNet, although Siemens systems are the largest user of the protocol. ProfiNet cables do have a shield which helps to reduce transients on the cable and helps eliminate induced voltages which can affect communications. Any "flavor" of Ethernet is susceptible to "noise" when installed in an industrial setting. Shielded cables are needed to provide reliable and error-free communications.

[@ardentdfender4116]

Hi! Great video! Quick question, would it be possible to implement a custom PROFINET controller, say, with a microcontroller? Since some of them already have Ethernet support. Thanks a lot!

[@realpars]

Profinet Ethernet are both Industrial Ethernets, but are distinct protocols with different application stacks in their communication processors. A custom Profinet controller really cannot be implemented from an Ethernet controller. However, many companies, such as ProSoft and RTA, sell Ethernet to Profinet gateways that allow the two protocols to coexist on the same network See:www.prosoft-technology.com/Products/Gateways/PLX3x/PLX32/EtherNet-IP-to-PROFINET-Gateway-for-dual-subnets. \ I do this all the time for connecting Siemens-controlled equipment skids to an Ethernet/IP network.

[@jcl0511]

my understanding is that tcp/ip is used between computers, and rs-485 is used between controllers. according to this video. profinet h/w is rj45 . same as ethernet. so. could i understand Profinet is the tcp/ip? which is able to be used in Controllers? then DCS side could configure such as tcp/ip? So S/W & H/W configurations are same as TCP/IP Between DCS & PLC?

[@realpars]

Hi there, Thank you for your question! Profibus, Profinet, and industrial ethernet are communications protocols. In other words, the software features. And TCP/IP is a set of rules and procedures used in the protocol, the same as RS485, and RJ45 is the name for the cable used. You can have all protocols in your system included in a DCS. It depends on the hardware you use and the software installed on your system. Here is a link for your review on communication with Siemens PLC systems. CPU-CPU Communication with SIMATIC Controllers. support.industry.siemens.com/cs/products?search=communication%20with%20simatic&mfn=ps&o=DefaultRankingDesc&lc=en-US Happy learning!

[@jcl0511]

@@realpars thank you for your reply. so profinet can be used for simense internal communication. and at that time . if the plc groups communicate with other system such as dcs. then the communication between plc and dcs can use either rs485 or tcp/ip. regardless of plc internal communications?

What is ET 200S & DP/PA Coupler? Please explain

[@realpars]

Hi Sharif, Thanks for your comment! That is a great topic suggestion, I will happily go ahead and pass this on to our course developers. Happy learning and thanks again for sharing!

[@realpars]

DP/PA coupler is a device that allows a Profibus PA segment to be joined to a Profibus DP network. Siemens PLCs do not have native Profibus PA ports built into the processor but do have Profibus DP ports. So, when a Profibus PA network is used to interface transmitters and control valves to the control system, a coupler is used to join the PA segment to the DP network. ET200S is a compact CPU and distributed I/O system into one hardware profile. The ET200S can be thought of as a small S7 CPU with limited capabilities used for single machine control. The ET200S is being based out and has been replaced by the ET200SP, which offers additional I/O choices and a more powerful CPU.

I was wondering what'd be the differences between profinet and snap7 protocol?

[@realpars]

ProfiNet is a defined protocol that is based on TCP/IP and is built-in to many devices and controllers to allow easy setup and configuration of the control network. Snap7 is an open protocol that is also designed to work with Siemens S7 hardware, but it allows the programmer to communicate with the hardware via a .NET or C program, giving the programmer greater flexibility in interfacing PC-based applicatios to the PLC. However, the programmer needs to consider all of the abnormal situations (comm loss, application fault, etc.) that are transparently handled when using ProfiNet.

[@winepim]

@@realpars Thank you so much for your reply, I was wondering if there is any Snap7 api that would allow a real time socket communication to the hardwares. For example, if M40.1 bit value changes, then it will reflect the change on the Snap7 program without having to poll or query this value every 1 second also... I hope I don't ask too many questions but I was curious to see if Profinet is much different than Ethercat protocols? I've heard that Ethercat is open source as well...

It is not recommended to extend or branch a bus using the service port on the back of the connector! Address 127 is absolutely not to be used! It is the broadcast address. Also stay away from 126 as it is used for devices that use the Set Address function. Cable segment lengths up to 1200m is allowed when baudrate is 93.75Kb/s.
