Profibus pneumatic regulator

[Innovia]

Hello,

I am looking for an electro-pneumatic regulator for controlling the air pressure using profibus.
Currently we are using ITV2000 regulators from SMC which take a 0-10V input signal and give a 1-5V output. I now want to get rid of the analogue signals and do the thing using profibus.
Does anyone know a supplier and/or have experience with such regulators?
Thanks in advance,

Peter

Not sure if this is the sort of thing you are looking at but Siemens combine I/O, pneumatics, PLC functionality and even motor starters/controllers on a profibus backplane. The backplane also includes all power network and control network. It's called the ET 200X. I was involved in the inverter development onto the ET 200 platform and remember the interest created a few years ago by the added modules for pneumatics (pneumatics is not my area but it seemed quite a neat solution) and profibus as well as ASi.
