Delay Node Stacking problem

General
1

I currently have a message delay set for 2 minutes.in a "Delay Node". I've noticed that if a second message hits the delay input prior to the 2 minute delay, the second message is stacked. The first message completes it's 2 minute delay and is output, The second message is then output after it's 2 minute delay.

Rather then having messages stacked I would like to see the first message start the 2 minute delay, and all subsequent messages keep resetting the 2 minute delay until the 2 minute delay can complete outputting the first message. Is it possible to reconfigure the delay to stop the message stacking?

I think you want the trigger node then.

smcgann99 you're right. Just looked at the "Trigger Node" and it looks like it will do the job. I need to rearrange my nodes; I had a function node sending a message to the delay. Now I need to have the trigger-node activate the function node.

Thanks again, X (formerly Twitter, just kidding lol)

UPDATE: It works and I eliminated the Function Node; the Trigger outputs the string.
