# Edge Data

If you're using a TilliT Edge device, you may want some of your machine data to appear in the activity form.

First, you need to make sure that you have configured the data you need going to the [edge](https://help.tillit.cloud/tillit/knowledge-base/setting-up-tillit/edge/edge "mention")and assigned it to a [process-variable](https://help.tillit.cloud/tillit/knowledge-base/setting-up-tillit/configuration/process-variable "mention").

Once you've configured that, using the Edge Data element is easy. Simply define the required Process Variable that the Edge is publishing to.

In the following example, we are using a Process Variable called "Temperature" and the tolerance that is defined on the process variable, though you can define the tolerance elsewhere, or have no tolerance at all.

This temperature is from a sensor connected to the PLC, which is feeding the data to the TilliT Edge, recording to the process variable.

From the operators' perspective, we can see that the temperature is 14°C, which was recorded a minute ago. The tick by the target confirms it is within the tolerance allowed and will pass.

Should the temperature fall outside the allowable tolerance, the tick will change to a warning triangle, letting us know that it will fail.

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://help.tillit.cloud/tillit/knowledge-base/setting-up-tillit/activity-templates/activity/elements/data-types/edge-data.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
