Dear All!!
Can somebody help me .
I have problem with my laptop with installed Siemens simatic Manager S7 V 5.5.
In start was all working fine but after I remove hard disk and put inside new hard disk when I connect to CPU online
he reads and show me totali wrong status in program. I put back old hard disck but problem is the same.
Online view is not correct.
First I think thet is problem of MPI adapter but then I used my old laptop and on them all working fine with the same adapter.

Can somebody tell me how to fix it.
Can bi some virus .
I hope is not Stuxnet?
