Hi,

I have to design an architecture, and i want to take your advice about it,

Architecture:
in the picture that i join to the thread, i have three of
- S7-200
- TD200 TEXT DISPLAY mustcommunicate with this S7-200
- TP177 MICRO TOUCH PANEL must communicate too with this S7-200

All this three of S7-200 must communicate with a PC having Wincc RT.

Questions:
- I propose to use profibus, wired serialy, but i don't know if this protocol will supportsthis architecture,
-Can i use MPI in place of Profibus to be more competitive?

can i have your advices? improuvements?

Thanks,
MED.AADI.
