CPU 1517F3 remote hardware chenges

Dear All

I realy need help with this one

TIA Portal v16
CPU 1517F-3 PN/DP

In my Profinet network I have:
6 of ET200 IO modules
1 of 1214FC CPU
1 of 1512SP CPU
3 of TP1500 comfort
80 of Movimot motors

I am connected via a VPN to X2 on the PLC, and wanted to add a module to one of the ET200 IO modules, (thay are all connected to X1 on the PLC)

After the change I cant connect to 5 of my ET200 IO modules, everything else looks OK

Any idea what I am doing wrong?

Found it, one of the electricians had connected a second PLC system to my switch with some of the same profinet names
