Thank You Bjornidar.
I deleted the screen and added it again. The problem disappeared. Don't know the reason.
What is the difference between "&" and "&&"?

Thank You Stuart.
Is it possible to use the Google Maps on T7A offline?

It should work. Maybe, You forgot to refresh the tag with the newly changed file name? Something like:
Globals.Tags.FileName.Read();

Which colours schould be used in Alarm server to make alarm and warning messages easy readable? Real colours on HMI do not correspond those which are chosen in IX Developer.
Is there somewhere the recommended values?

Did somebody put a map on screen with information about some events?
I have tags with data including GPS coordinats. How can they be shown on screen?
Regards, Waldemar

void Stopping_state_ValueOn(System.Object sender, System.EventArgs e) {//record trend to USB when the system stops Globals.Tags.Last_session_number.Value=0; if (Globals.Tags.History_trend_recorded.Value==false) { Globals.ExportTrendData.ExportTrend("Datalogger1"); Globals.Tags.History_trend_recorded...

It is calling from 2 places:
1. Button "Record data to USB", placed on the screen "Statistic".
2. Tags>Scripts> aTag's_ValueOn, when 2 other tags meet conditions.

Thank You Edmund, works fine! What is confusing, every time when HMI power up, the new popup screen appears. How can it be prevented?

Regards, Waldemar

I created a popup screen and open it with the code:

Globals.MyScreen.Show();

How can I close the screen using script?

regards, Waldemar

Thank You Stuart.
