Hi everyone

I would like to know the maximum number of s7-1200 cpus i can connect with a simatic PC station using only IE_CP adapter all in the same profinet network

I have 15 cpus connected and when i launch the RT , some of the values coming from different cpus are shown and other are not (display #####)

What can i do in this case! If i would need a specific hardware, would you place point me in the right direction

Thanks

Hi Badreddine,

AFAIS the max nº of connections (S7 )that a WinCC RT Advanced can manage is 8.

Hi Badreddine,

 Thank you for the reply 

So how do i manage to have all 15 or more cpus in my network ?

What's the workaround here ? 

Thank you , but i didn’t quite understand the second proposition, could you please explain more ?

Hi Badreddine0077,

What @0_Einstein is referring to is to configure 7 S7-1200 as I-Device (Configuration and Application of the PROFINET I-Device Function) and in this way only need RT Advanced the other 8 which would be configured as IO-Controller. I attach a picture of the schematic that would result.
