PROFIBUS driver?

[Andreas Vogler <an...@me.com.INVALID>]

Hi,
Is it planned to implement a PROFIBUS driver?
Regards,
Andreas

I don't know much of profibus (yet) and miss test hardware, but it seems
to rather have descending adoption, isn't it?

From what I recall its communication medium is compatible with EIA-485
and have typical serial bus characteristics. Do you happen to know
converters/hardware which can create an transient serial port?
In such case we could try to implement profibus frame from (OSI layer 2)
and application layer (OSI 7) covered, still delegating time sensitive
operations which require bus participation to the adapter.

Per say - the trouble is rally transport which does not tie us to the
hardware which change frames. Quite many industrial converters bring
their own SDK's which in most of the cases are DLLs available only for
certain systems or micro controllers.

Best,
Łukasz

AW: PROFIBUS driver?

Hi Andreas,

let me also jump into the discussion here.

We will probably not support ProfiBus in PLC4X.

In contrast to ProfiNet, which is ethernet-based, ProfiBus requires dedicated hardware for which dedicated drivers are needed.
This would mean that we would need to implement a transport layer for every supported hardware device.

Yes, the whole idea of PLC4X is to support as much as possible.

 The limitation are ressources:
- Budget so that the developer gets paid
- Time so if you or someone else wants to develop a driver do not hesitate to ask and just do it
- Access to devices and / or manuals for the specific protocol is missing (so it makes it difficult for the developer to build and test a driver)
