Hi Ladan,

As far as I'm aware it's not directly possible to add a timer on an automation script. There are some ways however to trigger it periodically:

• Create a scheduled task that will run your script for a given interval: every x minutes, hours, days, ... or on certain moments specifically.
• Trigger the script when an event happens. This could be done with a correlation rule when a certain alarm, information event or a parameter change happens.
• User Defined APIs.

The following documentation page also contains an overview and link to the mentioned modules. Running Automation scripts | DataMiner Docs

Hope this helps!
