Interfacing smbus mlx90614 to profinet

Looking for a way to interface +100 mlx90614 into one single profinet. I understand that each chip can be configured with a separate hex value on the smbus. Getting to the profinet is the challenge.
One suggestion is to have smbus into serial rs232 then rs232 into profinet.

Open to ideas, sample code and trial and error.

Thanks

That sounds like you're trying to put all Mlx90614 onto the same smbus. That's quite difficult because you would have to solder one mlx90614 per 5mm bus because otherwise your bus get too long to work correctly, or do you plan to use SMbus expanders (PCA951X)?

I'd guess that the bigger problem will be to get the Profibus/Profinet protocol onto the Arduino because as far as I know this protocol is not publicly available. It's much easier to get electrical compliance than to achieve that in the software layer.
