If you have not already done so during configuration of the Industrial Process Manager, assign users who already have either the
cmdb_ot_isa_viewer or cmdb_ot_isa_editor role to sites.

## Before you begin

When OT devices are in the CMDB, site access can be configured to limit visibility of OT devices to users with both a cmdb_ot_viewer, editor, or admin role, and a cmdb_ot_isa_viewer or editor role.

Role required: cmdb_ot_isa_admin

## Procedure

1. From the Equipment Model Entities form, select a parent Equipment Model entity.  
   For information about equipment models, see [Managing equipment models](https://servicenow-prod.fluidtopics.net/6WgfZHo9PvIhqDnwUbQmEQ "The Equipment Model Manager in the Industrial Workspace enables you to review and manage ISA-95 equipment model data. You use it to review imported equipment model data or to manually create an equipment model.").
2. From the Site Users tab, select New.
3. On the ISA Entity Sites Users form, fill in the fields.
4. Select Submit.  
   The user is assigned to the site.

## What to do next

[Assign users to assignment groups](https://servicenow-prod.fluidtopics.net/gCJdwBdPwQ1NQUPe~8UImg "Add users to assignment groups so they can see the vulnerability items for their assigned site.")
