How to Wire a Profibus Cable to a Profibus Connector

✅ C'mon over to realpars.com where you can learn PLC programming faster and easier than you ever thought possible!
==========================
Profibus is a widely used communication protocol for Siemens industrial applications. If you did not purchase a pre-wired Profibus connection or one was not provided for your application, you made need to wire one yourself.
In this video, we are going to discuss what tools are needed for wiring the Profibus connector as well as the different steps required.
We will talk about what the different layers of the cable are called and how to strip those layers to get to the core wires required for the connector.
Go ahead an watch this lesson to learn how to wire a Profibus connection cable.

[@hectorenriquesantandermeza5208]

Excellent explanation as always Real Pars. I have a question. Is it necessary to strip the green and red wires, and leave the conductive material visible? Or are they just connected as they are to the DB9 terminals?

[@realpars]

It depends on the the physical connector you are using. The ones shown in the video use "vampire" connections, where the clear plastic tabs force the conductor down into a metal connector that cuts through the insulation. Some connectors require terminal connections, in which case, stripping of the conductors is necessary.

[@mohamedhafez1641]

Thanks so much for this valuable video. I have one simple question, why the two cores are inserted in only one path of the two paths connector?

[@realpars]

Profibus DP operates on a two-wire network. In the video, wiring the "IN" network side of the connector is demonstrated. The two cores are (+) and (-) and are both parts of the incoming network connection. Profibus DP is a multi-drop network, so the connectors also have an "OUT" network connection so that the network can be run to the next node. In the case that there is not a "next node" (the current device is at the end of the network), there is typically a switch on the connector that allows an end-of-line resistor to be placed in line to terminate the network segment.

[@kaustubhb4]

Dont we need to remove that last layer of insulation as like we normally do for regular electrical wire connections?

[@realpars]

Not with this style of Profibus connector. The two connection pads have "vampire connectors" which pierce directly through the insulation on each wire.

[@funtikos]

You teaching best shit. The baddest way to do this.

[@realpars]

Thank you very much!

[@haan123456098]

QuicK question: if i want to install another cable on the other 2 terminals and the colors are swaped will it effect communication means on the other connector i connect red in A2 and Green in B2. The connector i have there is no color marking

[@realpars]

Hi there, Yes, it affects communication for sure. There may be + and - signs instead of Red and Green colors on your connector.

[@erickontiveroslara209]

Why does the connector has tow wire paths and, isn't it necessary to connect somewhere the braided shield ( because of noise effects)?

[@h20no63]

Erick Ontiveros Lara 2 wire path is for another set if your not using the terminating resistor on the connector. And I believe that metal part of the connector being is supposed to be in contact with the braid. But he has the aluminum shield on it . Not sure if that's right.

[@erickontiveroslara209]

h20no Thanks 4ur feedback. Inspired by you I'm currently reading an article called PROFIBUS Instalation Guideline for Cabling and Assembly, from Profibuscentre and I now have the answers; they recommend to read manufacturer's instructions about the connector's design and use. In general the shield of the cable must be connected to the shield of the connector (which is provided by a groove on the connector), and this can easily be prooved on the video, before he closes the terminated field assembled Profibus cable. On the other hand, just like you said, the other path (outgoing signal) most only be used when you have a Profibus network and wanna add another device or segment, otherwise you'd activate the bus termination built into the connector. Thanks again!

[@realpars]

Hey Erick, thanks for the comment. I guess you've got the answer to your questions by now. But just wanted to add that if you do the wiring and connections the way we do it in this video, everything is going to work perfectly fine. We've done this hundreders of times for different projects. Don't get confused with the manuals and shield stuff the way I did when I was new to Profibus. :)

[@erickontiveroslara209]

Yes, you're right! Sometimes manuals are confusing

[@ghanshamshirbhate1034]

What about the terminating resistor, is it inbuilt, if yes, where?

[@realpars]

At 2:46 in the video, a Profibus connector is shown. Look on the back of the connector. There is a red slide-switch that is set to put the terminating resistor inline or remove from the circuit. So, the terminating resistor is in the connector shell, and the slide switch allows it to be used or bypassed.

[@yassershalaby834]

Why did not you remove the insulator from the red wire and green wire?

[@realpars]

When you use this kind of connector., you don't need to cut those wires. When you close the Profibus connector, it will cut the wires automatically.

[@yassershalaby834]

RealPars Thanks a lot

[@MertMusaTemel]

If your connector has screw terminals inside it, you should remove insulator.

[@behelpful1435]

In the inside of the wire connector, why is there two sets of clear plastic wire inserts?

[@realpars]

Thank you for your inquiry. The clear plastic wire inserts are designed for managing cables. There are two inserts labeled B1 and B2 for the specified connection type. These inserts facilitate a daisy-chained configuration, allowing one cable to go in and another to go out to other devices if you have multiple devices in your network. To provide you with more detailed information, I'm including the current Siemens web link: support.industry.siemens.com/cs/start?lc=en-US Once you access the page, enter the ID number 109793857 in the "PRODUCT/ARTICLE BOX." This will lead you to the information page where you can either download or view the PDF book on the connector, its usage, and additional educational content. Happy learning!

[@amanishayria3810]

How long do these connectors last before you need a new one? anyone can please tell me?

I don't think you need to replace these connectors after a specific period of time if you are using them in normal industrial environment.

[@suriyat8773]

[@danishsaleem6402]

What about this on off switch on your connector's back..

[@realpars]

At the end of each segment, you should turn that switch ON to terminate the line. In the middle of the segments, you should keep if OFF.

[@danchiriac2887]

you didn't say anything about setting the resistance, it looks like your connector is the last one so you need to set the resistance, but overall a very good movie, thank you.

[@ananyanayak9793]

There is a provision for connecting two profibus cables in a single profibus connector. Why is it so??

[@realpars]

Profibus DP is a multi-drop protocal. The devices are "daisy-chained", so each connector has an IN connection and an OUT connection. The Profibus connectors have the internal connections that makes this easy to accomplish.

[@Profit4Hondo]

Why does a two wire cable require a DB9 nine pin connector?

[@realpars]

Profibus DP technically does not require 9 pins. When Profibus DP first came on the scene, DB9 connectors were the standard for automation systems. Because Profibus DP cables need to carry the network power, smaller cables like CAT 5 cables not have the capability to do the job. The size of the DB9 shell connectors is perfect for connecting the 'in" and "out" segments of the Profibus cable and connecting the foil shield to ground.

[@jaimemunoz5920]

So are these cables still used? Or has pretty much everything gone to ethernet cables?

[@realpars]

ProfibusDP is still widely used, although Profinet (an Industrial Ethernet) is gradually replacing ProfibusDP.

[@boostyourbrain345]

Why don't you removed the insulator for wires. Doesn't it require??

[@realpars]

When you use this kind of connector., you don't need to cut those wires. When you close the Profibus connector, it will cut the wires automatically.

This is a tragedy. The author of this film did not notice that we are in the 21st century. He stopped in the mid-20th century. How can you show cable processing with an ordinary knife nowadays? I'd like to see what he did up close. What does the insulation of the wires look like? I know that sometimes he will do better, sometimes worse. I have seen the work of such specialists many times. I know that there are people who learned how to peel cables with such a knife 20 years ago and will continue to do it for the rest of their lives. But it is very harmful because when a young person watches it, he or she learns bad habits. Now there are tools to help you do it professionally.

[@realpars]

Thank you for your question. You have a point. This video was done in Europe, where most technical assembly and field service techs get extensive apprenticeship training before being allowed to do such a job. Our videos are made for a worldwide population of students. This is why we included the Siemens part number for the tool of choice today for accuracy, speed, and safety first. And, of course, because of the ISO standards, you want it built right. I personally started 45 years ago with the knife and was not allowed to touch customer products until I was certified by an instructor after I spent 40 hours practicing on cable. I was a Siemens manufacturing engineering employee for 25 years, now retired and teaching others how to do it in today's fast-paced industry and doing it safely, too. I wish I had the new cool striping tool when I was learning!
