Hi Ruslan,
I have watched the video many times and still can't connect to the sever via Teslascada RUN TIME. There are still some unclear problems in the video.
1) In the video he didn't explain the IP he put in when he creat the Siemens sever ( also the port)
2) I don't see any running programe that was on while he start the project in RUN TIME.
If there is no more futher setup in TIA Portal I think I did it just right (check in PUT/GET, download simple ladder and go online the stimulation PLC s7-1200)
T^T I tried many ways but faild to get it to connect.
Once again thanks for all the supports.
