Periodical task

[Redney]

I need to program a part of the code is executed periodically every so often, ie every 1 hour or every 6 hours.

Inside of a loop, compare the time using get date time with your target time. Use a case structure to execute the code you want periodically executed. Don't forget to put a 1000mS or so delay in the loop so it doesn't hog the CPU.

Here is a simple example. (I was on my phone when I posted so obviously could not work up an example for you)

There are also a couple examples of a simple timing Action Egnine posted in the Minneapolis LUG board here

The AE approach is a bit cleanre if your vi follows a classic State Machine archtecture.  It probably should from your discription containing Init, Measure, (possibly  Process / file), Idle and Cleanup states.
