Automatically back to Main HMI


Recommended Posts

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

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

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?

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
