Connecting Profibus slave devices ?

[GeoffS]

I have just come across your Revolution Pi device. Very nice looking. I was wondering if you have a solution that would allow connecting one or more Profibus DP slave devices (eg, a Profibus pressure transmitter) to the RPi ?

Hello GeoffS,
yes, we have a Profibus DP-V0 slave module which is available here
https://revolution.kunbus.de/shop/de/re ... ibus-slave
We have a small tutorial how to setup with the RevPi unforutnately currently just in german.

But fortunately the product manual is available in english, here:

Just realized thatt you have asked to connect PB slaves to our RevPi. Sorry but that is actually only possible when there is a master device on the PB bus (like a PLC) on which the RevPi could be another slave.

Thanks for the reply Dirk and the information on your slave modules. Yes, I was looking for a module to act as a Profibus master on the RPi (so we could avoid having a PLC as the master).

Hi,
just to complete the information: we will release a modbus master /slave software stack (with ÜiCtory asa configurator) very soon and we will release a profiNet master software stack for the RevPi also in the 1st half of the year. A profiBus master hardware module is under construction but will probably not be released this year.

Sorry for my ignorance, but does this mean, that with the profiNet master stack, we could read values from an inverter with a profiNet IO device interface, when there is no PLC on the network? If so that's what we are looking for.

[volker]

Yes that is something you could do. But I can't give you a definite release date for the stack.

Perfect, can't wait for it.
we have a setup to test it right away

Hello There,
Is there any new information regarding the software for generating a profinet master?
We would be very interested in using it.
Please send me a message, once it is released, please.
Best regards,
Guilherme
