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 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. 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 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. 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 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 Link to comment Share on other sites More sharing options...
GetAGrip Posted September 4, 2023 Report Share Posted September 4, 2023 There is a screen saver built in. It is worth using because that is the only way I know of to de-active the back-light. Turning of the Back-Light is important since you only get 30k Hours or 50k Hours (depending on model). After that you a purchasing a new panel. I would like to know how to detect a new VNC connection so I can deactivate the screen saver though. With the screen saver active a new VNC connection starts with a blank screen (until you click randomly). Link to comment Share on other sites More sharing options...
NoamM Posted September 5, 2023 Report Share Posted September 5, 2023 Hi @GetAGrip, You can use the next System tag to apply logic when a new VNC connection starts Link to comment Share on other sites More sharing options...
