In this video, you will learn about Fieldbus.
Fieldbus isn’t really one thing but more of a collection of things.
Fieldbus is a group of protocols that are used in the industrial arena.
The Fieldbus protocols have been standardized as IEC 61158.
Basically, Fieldbus works on a network that permits various topologies such as the ring, branch, star, and daisy chain.
Prior to Fieldbus, industrial controller systems were connected using RS232 serial communications. 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 controller.
However, Fieldbus is not a connection type, per se, but instead, a description used to indicate a group of protocols.
There are several protocols in the group such as ControlNet in the Allen Bradley family, Modbus, Profibus, EtherCAT, HART, CIP, and many more.
A primary benefit of Fieldbus is for field connected devices. For instance, consider you have several field devices that are quite a distance from your controller.
With Fieldbus devices such as sensors, motors, lamps, switches, these devices are connected to an “I/O data block”, which is then connected to a “field distribution device”, which is connected to a Fieldbus power supply, then finally connected back to the Programmable Logic controller.

Thanks a lot, Emmanuel! Great to hear.
How to provide some diagnostic when there is some tripping of drives without any fault indication in the drives and has to establish it due some disturbance due to communication between drives and DCs
Any diagnostic possible
Without any diagnostic both Electrical and Instrumentation people unable to come any conclusion for the cause of tripping
Very useful. Looking at signing up for more.
Great to hear that, Eric! If you have any questions or concerns, feel free to contact us.

@@realpars Thank you i can't wait :)
The standard for communication protocols at 0:12 in the video is IEC 61185. Should this be not IEC 61850 instead?
Hi there,
Thank you for your question. I wanted to clarify that at the 12-second mark in our content, we mentioned IEC 61158, not IEC 61185. To assist you in your learning journey, I have provided a link to the official IEC website below for your reference:
webstore.iec.ch/publication/66931
We hope you find this resource helpful for your learning endeavors. Feel free to reach out if you have any more questions or need further assistance.
Happy learning!
Nice video! A video on CANopen would be great.
Hey Pekka!
Thanks for your comment and your suggestion. I will pass this on to our course developers!

Thank you very much...
You're most welcome!
Thx for this tutorial
You're more than welcome!
Very nice description ..
Thank you!
Excelente vídeo 👌🏻
Thank you, Josué!
Would it be possible for y’all to do one of these for Sercros? We use this type of network for our older Rexroth servo drives.
Thanks for your topic suggestion, and I will happily go ahead and forward this to our course developers.
Thank you very much for sharing again.
good basic info
Thank you, Jimmy!
Thanks for the vídeo! Where can i find which protocols accept each brand of plc?
Hi there,
Thanks for your comment.
Depending on which PLC brand you are going to use, it is better to refer to its Datasheet and specifications on its website and search for its supporting protocols.
By the way, all kinds of famous PLC brands such as Siemens, Allen Bradley, Schneider, etc. have some utility cards which you can add them to make them support other types of protocols.
In addition, there are some manufacturers that produce a variety of "Gateways" to convert their existing common network protocols (like Profibus DP or Ethernet) to other types that you may need. For example, you can use a Profibus DP/PA converter or a Profibus PA to Ethernet protocol.
muy buenos sus videos, me gustaría suscribirme a sus clases, pero esta todo en ingles. No tienen una plataforma en español
Gracias
Hola Jaime,
¡Gracias por tu comentario! Actualmente solo proporcionamos nuestros videos del curso en inglés, siempre puede activar los subtítulos en inglés, ya que eso podría facilitarle un poco la tarea.
Nuestras disculpas por cualquier inconveniente!
¡Feliz aprendizaje!
Can fieldbus use fiber optic cable?
Hi Lucas,
Thank you for your question! Yes, you can indeed use fiber optic cable. However, it's important to ensure compatibility by installing a converter in your PLC rack to transition from electrical to fiber, and likewise, a converter at the receiving end to convert from fiber back to electrical. Make sure to select the appropriate converter for your PLC and device.
ty
can you give me an example where fieldbuses are used in a smart home?
Instrument fieldbuses are usually not used in a home setting, mainly because there are more efficient and cost-effective ways to interface the relatively few sensors in a home. You could consider ethernet as a Fieldbus, especially for IoT devices with ethernet built-in.
@@realpars My teacher said that ethernet isn't a Fieldbus and I need to have some information about where a Fieldbus is used in a smart home. I was thinking about how temperatures, lighting, cameras, doors, and more are connected to a router or something via a Fieldbus which is then connected to the app you have on a phone. But I need some more developed answers, it's useless to search for information about smart homes online.
Can you make a video on scada programming and how to change Siemens scada programming one model to another model
Hi there, thanks for the topic suggestion! I have passed your request on to our creator team. Happy learning!
helpful, thanks à lot, i have never heard about ethercat and hart, is It possible to make à vedeo about the most used protocols
Hi there, you are very welcome! Thanks for the topic suggestion, I will pass your request on to our creator team. Happy learning!
Does the order matter in the profibus connection ?
No
Thank you
You are very welcome!

@@realpars Thank You Got DCS,HART protocol in common learnt from your content only ♥️Keep Uploading we love you
ethercat is industrial ethernet?
Yes, EtherCat is one of several protocols that are based on TCP/IP and can be referred to as an Industrial Ethernet. Ethernet/IP, Profinet, and EtherCat are all industrial ethernet protocols, although each is unique and cannot be freely interchanged with one another.
How to determine the length required and it's limits?
Every fieldbus type has a limit as to the bus length. For Profibus, the maximum length is determined by the bus speed selected. At lower speeds (93.75 Kbps), Profibus can be run 1200 meters . At 500 kbps, the maximum length is 400 meters. At 12 Mbps, the maximum length is 100 meters. The maximum length for ControlNet is 1000 meters with 2 taps (drop connectors) installed, and is reduced by 16.3 meters for each additional tap installed. With the maximum number of taps (48) is 250 meters. The "length" of a bus segment is usually determined by the total length of the trunk plus the lengths of the drops from the trunk to the individual devices.
@@realpars thanks a lot
5 seconds after 4:07 the sound cuts
Thank you for sharing, Charles! There is indeed a 2-second silence, but no information is lost; it's just how the video was edited.
