====Agent Walkthrough - Attachment====

In the [[agent_walkthrough_-_settings|previous section]], we set the rules for our [[weak|weak AI]] so that it reports when a value exceeds 100%.

We still haven't told it //which// assets to operate on yet though, or which properties to use.

This is done in the [[attachment|attachment]] and [[binding|binding]] steps, shown below.

===Attachment===

Attachment is where we choose which assets we'd like to connect our AI to.

In our example, we have a single asset in our system named **Main Pump**, so we will use the most simple attachment method, called //single//.

<code>
"attachment": [ {
		"style": "type",		
		"asset": "Main Pump"
      }
	]
</code>

===Binding===

Finally, we need to describe which //properties// should be connected to which //inputs// in our AI.

<code>
"binding": {
     "Load": "Main Pump.Load"
}
</code>

This tells Agency that the input named //Load// should be connected to the ARDI property 'Load' from the Main Pump.

===The Finished Configuration===

We are left with the following file...

<code>
{
   "name": "High Load",
   "style": "PropertyPattern",
   "normalise": "*",
   "data": {
		"pattern": ">100"
          },
   "inputs": [ {
		"name": "Load"
	  } ],
   "outputs": [ {
		"name": "Status",
		"style": "boolean",
		"threshold": "=1"
	  } ],
   "binding": {
		"Load": "Main Pump.Load"
	},
	"attachment": [ {
		"style": "type",		
		"asset": "Main Pump"
        } ]
}
</code>

===Tuning===

When we run with this AI, we discover that it's triggering quite often. It's actually fairly normal for machines and motors to run at more than 100% for small amounts of time - the issue is when they do this for extended periods.

We can add the //ondelay// property to our output - this is a number (in seconds) that the condition has to be met before an actual alert will arise. 

<code>
"outputs": [ {
		"name": "Status",
		"style": "boolean",
		"threshold": "=1",
               "ondelay": 60
 } ]
</code>

The example above would make sure that the load has to be more than 100% for greater than 60 seconds before an alert is raised.

===Doing More===

This works, but it would be very annoying to re-write it for each and every pump we had.

Why don't we [[Extending the Example AI Across Multiple Assets|extend this to cover all of our pumps]]?
