 Hi itafusna

My project made with Tia portal professional V16 and I disabled firewall.

Hi again,

No Updates installed for RT Professional?

Updates for WinCC Runtime Professional V16

Also, have you installed SIMATIC NET? It is necessary to install and license it because it is in charge of managing the communication drivers of S7 controllers with the Runtime.

If you have received RT Professional on DVD, there should be a separate DVD with the compatible version of SIMATIC NET.

Hello murof

I use Windows server v2016

Hi yazdani,

There are still a few unanswered questions...

RT Advanced or Professional? Any software Updates installed?

If it is RT Professional, do you have SIMATIC NET installed and correctly licensed with SOFTNET license?

HI Others

I'm sorry for Pause problem solving.

As I told my connection is between one PC station with Wincc Prof and 20  s7-1200 plc station.

I didn't install SIMATIC NET, because of :

It is true that after execution  Runtime, the connection not work but  As soon as  refreshing network with "Accessible nodes" tool, it work properly.

for this reason, I don't know what help simatic net can do?
