# Automatically map all OT devices

# Automatically map all OT devices to an equipment model entity {#ariaid-title1}

Release version: Australia  
Updated March 12, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
An Operational Technology (OT) Amazing admin can trigger automated mapping of all OT devices to the appropriate ISA equipment model entity.

## Before you begin

The following plugins must be installed:

* [Operational Technology Manager](https://servicenow-prod.fluidtopics.net/1MVfNbKxG9cy_4aVyxPImA "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/9Zf0CzRMffGJ032T~aqsEQ "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.")

Role required: sn_ot_amazing_admin

## Procedure

1. Navigate to Industrial Workspace AdminIndustrial Process ManagerOT Subnet Mapping.
2. Select Map all OT devices to execute the Map OT Device flow.

## Result

OT devices are automatically mapped to the Equipment Model Entities listed on all active OT subnet mapping records. After the mapping is triggered, you can view the mapping results by selecting the link available in the information message from the list view.  
Note:  
Subnet mapping also supports Discovery created configuration items (CIs) for ISA equipment models.

  Create a new OT subnet mapping to associate with an equipment model entity.
* **[Map all OT devices within a subnet](https://servicenow-prod.fluidtopics.net/Hc~CmxrM6sT3w1C3gJxcqQ)**   
  An OT admin can trigger automated mapping of all OT devices within a selected subnet.
* **[Map OT devices to equipment model entities from the Equipment Model Manager](https://servicenow-prod.fluidtopics.net/a2V0Lr4VbyQgmeQVnjW3hw)**   
  Map Operational Technology (OT) devices to equipment model entities from the Equipment Model Manager in the Industrial Workspace.
* **[Map an individual OT device to an equipment model entity](https://servicenow-prod.fluidtopics.net/dxuH34Y3ft5msBDFuzNYuw)**   
  Perform on-demand mapping of an OT device to the ISA equipment model entity for the sites that you have access to.
