leen Posted May 12, 2022 Report Share Posted May 12, 2022 Hi, Is there an funtcion that the HMI goes back to his main screen after a setted time? Normally it goes to the main HMI after powerup, but it would be nice if does also after i.e. 10 minutes no use of the HMI Otherwise I can make it in the software to set a bit to activated the main screen. But I was wondering if there is already an option that I can activate Regards Leen Quote Link to comment Share on other sites More sharing options...
AlexUT Posted May 12, 2022 Report Share Posted May 12, 2022 No, there is no pre-defined behaviour like this. You have to realize this in Ladder. Quote Link to comment Share on other sites More sharing options...
Dave Posted May 12, 2022 Report Share Posted May 12, 2022 I create a duplicate of my start screen, but with a full screen "invisible" button with a "Last Screen" action. Then I use the system tag "General.Touched Bit" with a timer to trigger a project level action that loads my duplicate start screen ( "screen saver" ) and reduces the screen brightness, after 5 minutes with no touch screen activity. About the brightness...the change from 100% to 10% is barely noticeable. I wish it could be even dimmer Quote Link to comment Share on other sites More sharing options...
AlexUT Posted May 12, 2022 Report Share Posted May 12, 2022 You can review VisiLogic examples in \HMI\HMI Show. There is a Ladder code to activate screen saver with pictures. Quote Link to comment Share on other sites More sharing options...
leen Posted May 13, 2022 Author Report Share Posted May 13, 2022 I have test it by using the General.touched bit. But when we touching the HMI this bit is not getting high. While we using a PLC with a HMI connected by VNC I also tried to use General.VNC Touched Bit. This remotely and local, but that bit also not getting high: What can be the problem that the General.Touched bit is not getting high when touching the HMI?

leen Posted May 13, 2022 Author Report Share Posted May 13, 2022 I just found the problem. In the HMI you have VNC settings where you can select the touche function. Now it's working Quote Link to comment Share on other sites More sharing options...
NoamM Posted July 26, 2022 Report Share Posted July 26, 2022 In the manner of VNC I'm just adding:From version 30.XXX go to "UniApps -> Network -> VNC Server -> Set 'touch bit'" check box and press apply. The VNC server will restart with the "touch" identification option and will set General. VNC Touched bit upon "touch" of a VNC client connected to UniStream Quote Link to comment Share on other sites More sharing options...
