Hi professionals,

I have a problem. We want to simulate scada system our engineering pc.  CPU has 2 eth port. First one drive-IO line. Engineering PC connected this line. Second one scada line. Operator pc(scada) connected scada line directly. 

The engineering PC reaches the cpu but when I want to start the scada simulation, the values do not online. It looks yellow warning. Scada does not seem to be connected to the cpu.

Where could the problem be.

I add some pictures about problem. 

Thank you for your support.

Hello,

Please have a look at the following link:

Testing and simulating HMI projects (TIA Portal) in conjunction with SIMATIC controllers, PLCSIM and PLCSIM Advanced

Check the PG/PC interface. 

Best regards,

Wizard

Thank you for reply. Problem solved. Control panel>>Communication settings>>Acces point settings have to be same with Tia portal>>connections settings(Here CP_L2_1)

Ip addresses have to be same with scada port(Second port of CPU-maintenance PC)
