Once true, make LED stay green

[sterry]

I have an LED that lights green when a timer and set time are equal/greater than.  How can I force the LED to stay active?  Such as if the timer gets reset...  The LED needs to still show active.

You can use Boolean's Property Node > Value to set the boolean to high.

Use a feedback node. Wire the OR of current value and last value to the LED and back into the feedback node.

My only problem with that is that it's all constantly being looped.  Won't it just keep checking?  If the timer gets reset it won't match the set time then the boolean will just reset.  Attached is the code for what I have.

Or search the forums for a Boolean Latch. Such as the one in this thread.

In case you don't know the feedback node, here's the concept of latching using a shift register.

I guess I should have thought of that...

Start a new thread.  And post the actual code.  The pictures you gave is not enough information to diagnose the issue.
