When I create a WinCC connection and configure it, and then try to connect to PLCSIM v16, the connection status shows as "Unknown." I haven’t installed Simatic NET because I’m working with PLCSIM. What can I do to solve this? Thank you, bro. ------------------------------------------------------------------------------------------ Split from WINCC connection status unknown.

How do you have set up the PGPC Interface settings? Open the Channel diagnosis Tool and check the details while running (Screenshots would be great) Bye Murof
