How to connect 1100 Profibus DP nodes in AC500
From the help:
A PROFIBUS-DP network may have a maximum of 126 slaves (nodes). The physical medium for PROFIBUS-DP network is RS-485, which allows 32 slaves (nodes) in one segment. The segments in the network have to be linked together with repeaters
Only calculation: min. 9 CI854 and about 36 repeaters.
May be better is to have a local concentrators, collecting the signals from the slaves. Then to collect a values from the upper level.

1100 slave equipment in ProfiBus network are a big quantity of device...
Each master Profibus support up to 32 nodes without repeater or 126 node with repeaters, but one cpu can have max 4 Profibus device....
More CPU connected in one network?
Switch to AC800 series?
II've never had so many slaves to handle, it's probably better that you switch to a higher system like AC800, but we feel the opinion of some other colleague ...
In the attached file more info about ProfiBus performance on AC500 PLC
Hope this help you
