Freakers,

 

I am contemplating an endeavour into Profibus using this part:

 

https://gridconnect.com/profibus...

 

There is an evaluation/developmetn kit for it:

 

https://gridconnect.com/evaluati...

 

But at almost $2,000.00 it's a little rich for simply doing some experimentation.  I was/am hoping there might be a community member who might have one they would consider parting with,and if someone does have one I would appreciate a PM about it.

 

I am considering purchasing a few and making some experiment boards of my own, but having a working kit to start with would be a plus.

 

 

This device is supposed to be pin/functionally compatible with the Siemens device:

https://procentec.com/products/a...

 

But I prefer to stick with the first choice.

 

Any help appreciated!

 

Thanks,

Jim

I can't keep my self from wondering why anyone would want to invest USD 2000 in an 30 year old serial bus.

In the commercial maket price is moot if you can make more money than the investment, it just upp's the risk a bit.

 

At least is has an Atmel controller:

Extension Board with Atmel 89C5132 microcontroller[/gridconnect] I have never dabbled much with industrial busses (except my own RS485 contraption) but my general feeling was that modbus had become somewhat of a defacto standard.

Had a little peek & Ali (not the best for industriall stuff). Profibus connectors are usually between USD 15 and 20 ??? (It's 2 DB-9's back to back ???) and other Profibus stuff also seems to be a lot more expensive than "the rest".

 

Also had a quick peek at github. Just from the very low number of hits it is clear that Profibus is either not popular or a closely guarded secret.

For me that's enough to steer away from it real fast.

You must have some good reason to want to work with Profibus, and it makes me curious.

Why choose Profibus for "simply doing some experimentation"?

True, 

 

I did say that I could make up a few proto boards and go from there, but I have this nasty habit of wanting to start with a proven system to reference to when I am starting out on something new.  Kinda like what I, and another freak or two around here preach about using proven libraries before rolling ones own.

 

Yes, Profibus is 30 years old, but it is widely used in Industrial process control and a client I did a design for years ago has asked me to look into a way to make this product compatible with Profibus as they have a possible market for it...but unless I/they have something to show around then one never knows.  PLC's use Profibus a lot, as well as Modbus, and RS-485.  All very old communications types, and all very reliable.

 

As you noticed the Evaluation kit uses a very old 89c5132, that has no bearing on my desire to use the part.  Having some example code for the Mega128 DOES help.

Back in the day Profibus used to require very expensive ASICS, or FPGAs and since back then development kit/IDE for those devices was not for the small of pocket so it was left to the big boys.

I do have good reason and I think I explained it as much as I care to.  This thread is simply to ask if anyone has the Eval kit, and if they want to part with it to PM me.  

 

 

Cheers,

Jim

Phil used to be into Profibus IIRC, but he hasn't shown his face around here for a very long time. Ross may have his contact details still.

Jim,

 

Philip Rowse can be contacted via https://www.facebook.com/Proficn...

 

These days he is very heavily into Drone electronics but is a gentleman and will talk with you civilly (especially if you "dob me in")

The post that JS points to has a remark of a profibus project from user "proficnc" here.

https://www.avrfreaks.net/comment/594077#comment-594077

 

That link to project id 2587 seems to have died, but it is probably this one:

https://community.atmel.com/projects/profibus

 

Also found a project with the VPC3 on github (With STM32, but probably C ).

Wow, interesting project.

Sorry, I don't have a board for you.

 

Not sure if yo are going to implement the Mater or the Slave, but it looks like a non-trivial protocol, either way.

 

Of interest, and for your budgeting purposes for the project, you might want to consider getting a Profibus Tester or Profibus simulator.

 

Google "profibus simulator" for several commercial products available, which might help you complete this project in a more timely manner than doing so without them.
