An OT admin can trigger automated mapping of all OT devices within a selected subnet.

## 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. The Industrial Process Manager enables you to create your own version of the equipment models in each of your sites.")

## Procedure

1. Navigate to Industrial Workspace AdminIndustrial Process ManagerOT Subnet Mapping.
2. From the OT Subnet Mapping list, open the OT subnet mapping record whose devices you want to map.  
   Note:  
   Subnet mapping also supports Discovery created configuration items (CIs) for ISA equipment models.
3. Ensure that the Site and Equipment Model Entity fields are correctly completed.
4. Select the Map OT devices in this subnet UI Action to automatically map all OT devices in this site with IP addresses in the selected OT subnet.

## Result

If there are OT devices in the selected site with IP addresses that fall in the selected IP range, all devices in the site are mapped for the OT subnet. After the mapping is triggered, you can view the mapping results by selecting the link available in the information message from the list view.
