Hi, I'm new to the C-more. I was wondering what would be a good way to create a splash screen (display page for several seconds on boot up then automatically switch to a different page). Any good ideas? Thanks.

Set up the CMore application with Current Screen and Switch To screen fields set up. Set the 'start Screen Number ' to your Splash screen.
In the PLC, if the Cmore is on the 'splash screen ' start a timer. On time out use the 'switch To ' register to change it to the next page.

This can also be done using the C-more event manager - without needing any code in the PLC:
In the event manager set up an event that sets SYS COUNTINTERVAL to - say - 1000 (it's in msec), and SYS COUNTMAX to - say - 10. Have this event triggered on SYS BIT ON being "on " - in other words whenever the panel is powered-up. Whenever those two internal variables have non-zero values the internal counter will count up to the max value.
Then set up an event based on SYS COUNTVALUE = 1 to go to your splash screen, and another for when SYS COUNTVALUE = 10 to go to your initial "real " screen.
You will get the splash screen for 10 sec. You can obviously adjust the values to suit your purposes.
The SYS COUNTMIN and SYS COUNTREPEAT internal variables can also be used with the internal counter for various other purposes.

If you use the internal counter for this purpose(splash screen) - it might be best not to use it for any other purpose - as a change of state to "1 " or "10 " at any point will cause the screen changes to occur again.

Thanks to both of you for your quick and helpful replies. Is that the only timer that is available on the display? Seems like it would be helpful to have more, though I suppose there are ways that you can fake around that limitation. In this case perhaps setting the minimum above 10 and starting a new count there.
Thanks!

If you control the Display Screen from a PLC, you can detect the HMI booted up, and force the HMI to a screen for a period of time, this assumes your PLC is running before the HMI boots up. Otherwise, you can also use an event to tell the PLC the HMI booted up, and use that for a trigger to do the same. You can also use the Background Graphics Screen to display a Spash type of indicator. I use this for STARTUP Warnings. It appears on any screen since it is a graphic on the background included in all screens.
