[Danfossegypt]

Have a look at the Foxboro I/A system and the Emerson Ovation system. Both are high-end DCSs and you will learn a lot about the principles and architectures employed.

The protocols you mention are well documented on the net. Try Google for each of the ones you are interested in.

Think you miss the hole point: those words are just the communication protocol of the DCS. The main task of DCS is to control, monitor and collect the data from the plant it installed in.
