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: ```auto if(system.tag.read("enable").value == 1): system.tag.write("count", system.tag.read("count").value + 1) ``` You will need to handle rollovers. ---

Consider recording start and stop timestamps to be precise. Something like [this thread](http://forum.inductiveautomation.com/t/timer-component/17125).
