KB-34475: Opening or closing a screen according to a tag’s value.

How can I execute a script to open a screen whenever a Boolean tag’s value is 1 (one), and close it when it is 0 (zero)?

Solution:

To do so, follow these procedures:

• In the Boolean Tag, add an Alarm in High with value = 1
• In the Scripts window, create the following script in the OnAlarm event to open the screen: Screen.Show()
• Create a script in the OnAlarmReturn event to close the screen: Screen.Hide()

Thus, whenever the tag’s value is equal to 1 (one), the screen opens; whenecer it is equal to 0 (zero), it is closed.
