Gateway Script timer

How do you make a gateway script counter to count in seconds and write that time to a tag? I want the trigger for the counter to be on/off state of a multistate indicator.

You could have a boolean “enable” tag that is set by the multistate indicator. Then a “count” tag to store the seconds value. In a 1000 ms gateway timer script put the following:

if("enable").value == 1):
	system.tag.write("count","count").value + 1)

You will need to handle rollovers.

Consider recording start and stop timestamps to be precise. Something like this thread.
