Hi
your comments is correct,Feilbus foundation(FF) is a replacement for DCS in industerial plants and moves the concept of networking to industerial plants.

I do not want to design the whole system.Because the FF is a standard and have interoperability each part can be designed seperately and your can buy system parts from many companies then integrate the control system.like the PC that many companies build different parts of it(case,monitor,mouse,keyboard,graphic card ,CPU,...)
you can buy all part from different manufacturers and assemble the PC and it work with no problem,because protocols and hardwares are standard and at hand for any one that want it.

I want to design only the field device board this is a small board with a H1 protocol stack inside it.
I think I can build it for more info on field device see www.finc.com

if you have any comment or experience please share it with me.
bye
