Why does the WinCC Login box appear in SIMATIC WinCC V6.0 Runtime
instead of the expected SIMATIC Logon service Login box, although
SIMATIC Logon service V 1.1 was correctly installed?
Check in the WinCC installation path, respectively folder
"aplib/Options", whether the file "passlogin.fct" was renamed in
"passlogin.sav". Instead of the file "passlogin.fct" , the folder
"aplib/Options" now contains the file "passlogon.fct".
Afterwards regenerate the Header in the WinCC Script C-Editor
and check whether the project function "passlogon.fct" is
Fig. 1: Regenerate Header
Afterwards restart WinCC Runtime
