# Polling

To set up a scheduled poll that will query the remote system at regular intervals, pass data to a subsequent poll which will check whether any data has changed and then pass that data to Unifi, we will need to configure two each of the following records:

* Poll Processor
* Poller

We will look at the polling records in turn over subsequent pages. Before configuring those records, let’s first look at **Connection Variables**.
