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://servicenow-prod.fluidtopics.net/KXOAO5j4tYMj5sCaDmbvDA "The Operational Technology Manager application creates the foundational data and relationships that enable your organization to use the ServiceNow Operational Technology solution. Operational Technology Manager supports the use of the Configuration Management Database (CMDB), Service Graph Connectors, and Discovery applications in the ServiceNow AI Platform.")
* [Industrial Process Manager](https://servicenow-prod.fluidtopics.net/sOfsdd6CreweSY0OwphmoQ "Use the Industrial Process Manager application to create the ISA-95 Equipment Model data foundation that is required for the ServiceNow Operational Technology solution.

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 AdminIndustrial Process ManagerOT Subnet Mapping Scheduled Flow.
2. **Optional:** Activate site mapping:
   1. Open the Set Flow Variables section.
   2. Check the box next to Run Auto Assign Site and select Save.
   {#run-ot-subnet-mapping-scheduled-job__substeps_fzl_vw4_h5b}
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.
