hi All Experts,

 I have a query regarding CPU1517-3PN/DP, I am trying to make a configuration for my project with CPU1517-3pn/dp. i need to configure following devices on a single profinet  network

1. No of G120 Drives = 160

2 No of Remote ET200s = 80

3. No of HMI(Ktp400 pn) = 40

so total 280 devices are there i need to configure on single profinet network. i am also considering a CP1543-1 for increasing resources and have a plan that all 40 hmi i will conect to CP.

The topology is like as attached 

I have configured all devices  in TIA 15 Hardware and the compilation gave me no error but now if i see connection resources then it says it says station resources are 10 reserved and 268 dynamics... and CP has 118 resources ...out of these consumed no of resources it is showing total 4 +6+10 = 16 ....

i m confused i have configured all 40 HMI on CP and All other 240 devices on CPU's profinet then why it is showing only 16  resources used...

Is there any way to check whether my configuration is consistant and possible.

regards...
