• Sleep: When the device is in LowPower mode and a timeout expires
(@PWR_Time_To_Sleep_Mode), the device enters sleep mode. In this mode only the
RAM is supplied with power. Power consumption is very low.
Three events are defined for the project to which actions can be assigned: OnPowerOn,
OnLowPower and OnSleep. Actions can be assigned to these events by clicking on the
project name in the project tree and then select “Events” in the property pane.
The OnPowerOn Event is executed as soon as the device wakes up from sleep mode or
from LowPower mode (Ignition is plugged in again), but NOT when starting with a cold
boot.
The OnLowPower event is executed as soon as the ignition is pulled.
The OnSleep event currently gets executed as soon as the device wakes up from sleep
mode (before the OnPowerOn event). This may change in future so that the event is
executed as soon as sleep mode is entered.
To each of these events one of the following actions can be assigned:
• Execute Script
• Set Value
Some ideas for what these events can be useful:
• Jump to the home (start) page when entering LowPower mode by setting the Page ID to
variable @ProjektCurrentPage.
• Initialize variables with default values.
• Mimic the same behavior like a cold boot when the device returns from LowPower or
Sleep Mode.
By using a script, the ideas mentioned above can be combined.
The loading screen image should have the same resolution as the target device (e.g.
480x272, 800x480 or 1024x768)
Only PNG images are allowed as loading screen image.
The selected image will be renamed to 'loading_screen.png' and placed in the
'terminal_files/additional_files' directory in the project folder.
PClient will display the loading screen image as soon as it starts on the device.
How to show a progress bar:
PClient automatically draws a progress bar BEHIND the loading screen image. That
means if you want to show the progress bar, you have to make parts of the loading screen
transparent. Through this transparent area the progress bar will be shown.
The progress bar runs from left to right of the display. It starts at 10% of the display
resolution and ends at 90% of the display resolution. For a device with 480x272 resolution
that would mean that it runs from X = 48 to X = 432. The height of the progress bar is the
complete display resolution. If no loading screen image is selected, no progress bar will be
shown.
