Hi,

“Simple Samples” are small projects that demonstrate simple features. The target is giving a quick overview about the theme and be used as start point for related discussions. Follow there are a short description and the configuration main steps.

Sometimes it may be necessary to disable access to an application's controls, for example during screen cleaning operations.

This function can be done in several ways, in this example it is done as follows:

• A specific screen is created for cleaning functions where there is no control object.
• A tag (integer) is created for counting down time.
• A time schedule is created, which decreases this integer every 1 second.
• An IO field is placed on the cleaning screen as read only. In process value, a script is created that changes the screen when the count reaches zero.
• The main screen is placed the cleaning screen (button) taking care to pass a time value to the tag before to call the clear screen
