Hi Deema,

You should be able to achieve your goal by implementing a table similar to the one in Alberto's answer to another question.

Besides the table, you then need an extra timer that will have a frequency in line with what you want to be the smallest division your users should be able to configure (e.g. 1 1-second timer if you should be able to configure down to the second, or 1-minute timer if your users will only configure in multiples of minutes).

You can then use a QAction that gets triggered every cycle of the timer and checks which groups it should add to execution via Method CheckTrigger | DataMiner Docs.

Alternatively, you could use a combination of internal XML parameters, triggers, actions, and groups to decrement a counter stored in the internal parameter with every timer cycle. Once it reaches zero, you would add the desired polling group to the execution queue.
