This behavior can occur either when a timed loop fails to execute or when it becomes stuck in the process of completing its execution.
A Timed Loop does not execute if it receives an error condition. Because Timed Loops do not support automatic error handling, you must wire an indicator to the Error terminals of the Timed Loop's input or output node to identify any error that is occurring with the Timed Loop.
Timed loops can also experience difficulties if the processes within them fail to complete. It is crucial to ensure that when including subVIs, nested loops, or other structures within Timed Loops, they contain a finite procedure or can be stopped as needed.
