While I put winCC in runtime, Alarm messages are not available. I am getting No connection to data server! Please suggest. "CCAlgRtServer.exe" is in running state. Thank you..!!

Delete on the ES in OS-Project folder the file <osname>.dcf 2. Compile the OS-Server on the ES again with Server packages 3. Load the OS-Server again 4. Restart the OS And the user JazTai has described a solution in the post No Connection To Data Server! WinCC that has worked for him With regards Heisenberg

If you use the ES as OS-Server you have to delete the path of the OS and compile the OS again. With regards Heisenberg
