How often does a program run when the 'If' condition is Status? 

If
	Status 'Back Door' is On
Then
	$iVariable1 += 1
Else
	$iVariable2 += 1

If the Status is 'OFF', will this run forever? Will $iVariable2 be incremented to infinity and eat up all CPU to slow the ISY to a crawl?

Such a program never “checks” status.  Instead, the program is triggered when status changes.  If the door was always ON, the program would never run.

In my experience, It will also run ‘Then’ or ‘Else’ if you refresh the device status (or when the 3am update all is run) - based on its status.

When triggered by a change in the back door status, the program then or else section runs only once.

 

There is no 'continuous' in event driven software.
