How to run program once a minute

[salex319]

I want to run a program once a minute. 

I can do:

If 'HW Pump' Status is On

then

    Do something

    wait 1 minute

    Run Program again

else

    wait 1 minute

    Run Program again

1) Is this the way to do it?

2) If so how do I get it started?

Use repeat every 1 minute. If the pump changes status it will imediately switch from true to false or vice versa. It will start to run on its own first time pump chages status. Or click run at start up to trigger it at startup.
