Post by riccardo on Codesys SP19 patch 4 ^{CODESYS Forge talk (Post)}
Hallo everyone, I am working on new PLC of Weidmueller that uses Codesys SP19. I made the upgrade at the Patch 4 coming from patch 0. Unce made the upgrade everything is working well in the progect except the web visu user menagent. In the new version, when I perfom the login, I cannot use the keyboard of the device; the window where to digit the user name and password opens, the buttons "OK" and "Cancel" work but the system doesn't allow to put input from the device keybord, the mouse behaves as it is an image. If I active the virtual keypad or numpad it works otherwise nothing. I am wondering if it is a bug of the new package or if I must set something else. Thanks in advance, Riccardo.

Post by dkugler on Toggling Visualizations using HMI Physical Buttons ^{CODESYS Forge talk (Post)}
the magic option is named "Use CurrentVisu variable" activate this option in the Visualization Manager an have a look: https://help.codesys.com/webapp/_visu_obj_manager;product=core_visualization;version=3.5.14.0 if your button is pressed, "feed" the string varable VisuElems.CurrentVisu := 'visu1'; with the correct name of the depending visu. alternative: place a frame element at a empty main visu, konfigure all visus to be shown by this frame. With setting the switching variable of the frame to the index value of the depending visu, it will switch to it. Advantage: the visu names are not hardcoded as string in the ladder lodgic. Good luck! Hint: If you have multiple VisuClients(Target, WebVisu,...) all will show the same visu. Independent switching is much more difficult, but there is a example from codesys.

Post by wagokurt on CODESYS Visualization M License Fails to activate on Linux SL ^{CODESYS Forge talk (Post)}
The fix for this is when you install the control SL license, there is a checkbox for the Visu S license option. You must click this option. The Visu M is technically an upgrade to the Visu S, if this is license is not installed them the Visu M will fail as shown above. Thanks JoJo for the solution!

Well I created a user as Admin, gave access rigths to the file but still can't read the files in the plc it gives the same error. I guess is something to do with plc itself.

The problem (2) with the parent child conflict is resolved with Codesys V3-5 SP19 Patch 2 (Visu 4.4.0.0). The other issues unfortunately not.
