While dealing with another problem related to data export of the trend object, I uninstalled and reinstalled TIA v18, but after that, I couldn't establish the connection. I have made all the necessary settings that I previously did. The errors shown in the Trace Viewer file is attached.. 192.168.0.3 and 192.168.0.11 are online (PLC Sim v18) and the others not. (Previously, it was also like this) PG/PC interface setting is OK. Certificate is OK. But no connection. Thank you in advance for your assistance. Attachment TraceViewer.txt (66 Downloads)

Attach screenshot 3- Please attach a screenshot of the PG/PC interface 4- What problems do you have in the simulation, please explain the behavior better

It's frustrating not being able to solve the actual problem, but I didn't have enough time to do so. Thank you for your attention and suggestions.
