# Configure the OT Subnet Mapping scheduled flow

Configure the OT device mapping flow to automatically map OT devices to sites and equipment model entities.

## Before you begin

The following plugins must be installed:

-   [Operational Technology Manager](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/operational-technology/operational-technology-manager/operational-technology-manager.md)
-   [Industrial Process Manager](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/operational-technology/industrial-process-manager/industrial-process-manager-overview.md)

Role required: admin

## About this task

The OT device mapping flow can be set to run on a scheduled basis to automatically map OT devices for all active OT subnet mapping records.

## Procedure

1.  Navigate to **Industrial Workspace Admin** > **Industrial Process Manager** > **OT Subnet Mapping Scheduled Flow**.

2.  Activate site mapping:

    1.  Open the Set Flow Variables section.

    2.  Check the box next to **Run Auto Assign Site** and select **Save**.

3.  To schedule the flow to run on a regular basis, select the link in the Trigger section to define the interval.

4.  In the header, select **Activate** to activate the scheduled execution of the OT device mapping flow.

    After activation, this flow can run on a scheduled basis to automatically map OT devices for all active OT subnet mapping records on an instance.

    **Note:** Subnet mapping also supports Discovery created configuration items \(CIs\) for ISA equipment models.
