I open again this post because it's quite similar about our problem. We are working on a pharma project where we've installed the CFR21part11 license for Audit Trail. Software version on panel PC is : WinCC Advanced v13. As a standard solution, when Auto-logout is activated after time defined by Administrator, the system checks next instruction on the script and then everything is "close" on the HMI, and starts again on main screen, where the system asks again for another login. On this case, our customer asks to do: while the Auto-logout is switching-off the session of current user, the current background screen has to be viewable because the machine is still working and they want to see if there are any alarm, message, etc.. on the current screen. This mean that the next login has to be done inside a pop-up on current screen. Our Software Dept. has been trying to do it, but when the pop-up appears for a new login, the background of current screen is still active and the operator can change parameters while in theory should be out !!!!! We don't understand why the user have access to the parameters if Auto-logout is already done. Even, our technicians has tried to put a "transparent" screen over the current screen but without success. Please, could you send us your comments about how to solve this? ------------------------------------------------------------------------------------------ |
