We create a CRON to program an occurent event.
On the EDIT Layout, click on CREATE NEW button:
It opens all the spectrum of possibilities:
Here, click on CRON button and start creating it.
Let's take example of the request to uplink the aircraft that should be executed every 300 seconds.
Create the CRON: name it (here: 'my 5 minutes uplink')', click on pull service and set the pooling period to 300. In the ift below, write [FW.uplink(layoutId, delayInSec, opts)](/user-manual/designer-user-manual/edit-ifts/ift-v2/fw.uplink.md). Choose the layoutId you'd like to uplink and the delayInSec=0 (immediate).
When you save you should have a banner that asks you to make it belong to a [plugin](/user-manual/admin-user-manual/general-conf/configuration/plugins.md) - choose the plugin that you would like to have your CRON on:
Save again, and wait for at least 5 min in the uplink page.
If you want to add some triggering rules, it can be done here - under the IFTs ( if (A/C=XXX and not FLYING...) then uplink, for instance):
