Tia v15.1-The problem connection between WinCC professional with S7-1200

Hi NguyenDat1998

Do you use any password for the connection ?

Can you ping your S7-1200 PLC from your WinCC computer ?

Check also the aces point from pg/pc interface

Best regards

Firstly, you have to check your connection between your win cc and your PLC (network and connection) 

Then, go to your PLC and make a simple program like on/off a motor. After that, go to the wincc and drag and drop contacts from the program in PLC, also the importance is that you need to synchronize the data from PLC with win cc as the figure below. I hope that my idea can be helpful with you. Thank you. 

I have the same problem. 

Simulation is all ok when I test like these combination below:

- S71200 with WinCC RT Advanced

- S71500 with WinCC RT Advanced and WinCC RT Profesional

but there is no conection when I test:

- S71200 with WinCC RT Professional.

Hope to meet any idea for this problem. Thanks all.

Hi , I had a problem like this , 

I connected to PLC and downloaded my program to plc. 

But when I activated wincc RT advance, the wincc didn't have any connections with PLC. 

So I went to control panel , pg interface, and changed  the setting that applied by PLSIM installation. And removed PLSIM. 

The problem solved
