# OEE
To start capturing **OEE values** for a machine, you need to activate the calculation by configuring the required parameters in the ENLYZE App. This guide walks you through setting up **availability** and **performance** KPIs.
{% hint style="info" %}
What OEE is and how its components work together is explained under [Understanding OEE (Concepts)](https://docs.enlyze.com/en/concepts/understanding-oee).
{% endhint %}
Before starting, ensure that the machine variables used to define performance and detect downtimes are already in **active** status. Only active variables can be used in automations.
## Configuring Downtime Detection
{% stepper %}
{% step %}
#### Open the downtime configuration of the machine
Open the [ENLYZE App](https://app.enlyze.com/) and go to `Settings > Machines`.
At the relevant machine, select `Downtime Recording`, then click on `Set up downtime recording`.
{% endstep %}
{% step %}
#### Select a Downtime Parameter
Click `Select standstill parameter`. A searchable list of the machine’s **active variables** will be shown. Select one variable from the list.
Once selected, a preview of recent values appears. Use the **time picker** in the top-right to change the visible time range.
To select a different parameter, click the **pen icon**.
{% endstep %}
{% step %}
#### Configure Detection Logic
**Numerical variable:**\
Set a **threshold** to define downtime:
* Values **below** the threshold (`<`) indicate **downtime**
* Values **equal to or above** the threshold (`≥`) indicate **production**
**Boolean variable:**\
Choose whether **True** or **False** represents downtime.
Next, define the **minimum downtime duration** (in seconds). Shorter interruptions are ignored by the system.
{% endstep %}
{% endstepper %}
## Configuring Performance Recording
{% stepper %}
{% step %}
#### Open the Performance Configuration
Go to Settings > Machines. At the relevant machine select `Performance Recording` .
{% endstep %}
{% step %}
#### Select a Performance Parameter
Click `Add setting parameter`. A searchable list of **active variables** will be displayed. Choose one variable from the list.
A preview of recent values will appear. Use the **time picker** to adjust the time range.
To discard the selected variable and choose another, click the **bin icon** next to the parameter name.
{% endstep %}
{% step %}
#### Define Units
To ensure correct performance calculation, specify:
* The **unit of measurement** for the performance parameter (e.g. pieces, meters)
* The **time unit** of measurement (e.g. per second, per minute)
{% endstep %}
{% step %}
#### Set the Maximum Demonstrated Speed (MDS) Interval
Enter the **interval length** (in seconds) for determining the Maximum Demonstrated Speed. Our recommended value is 600 seconds (10 minutes)
{% endstep %}
{% endstepper %}

Congratulations :tada:
The OEE data collection is now configured. Your machine will start displaying performance metrics and downtime events on the ENLYZE App home screen.
