About Timers

A timer is an "internal time clock" that you programmatically create to perform an action each time the timer expires.

Timer duration can be between 1 and 2,147,483,647 millisecond (1 second=1000 milliseconds). The maximum duration of a timer is approximately 24.85 days.

When you work with timers you perform these steps:

  1. Create the desired number of repeating or non-repeating timers using the CREATE_TIMER Built-in subprogram.
  2. Create a When-Timer-Expired trigger that performs the desired action whenever your timer expires.
