# Assign users to sites

# Assign users to sites {#ariaid-title1}

Release version: Brazil  
Updated September 10, 2026

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 Configuration Management Database (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: admin or cmdb_ot_isa_admin  
Note:  
The cmdb_ot_isa_viewer_all access, which cmdb_ot_isa_admin also inherits, grants visibility to all sites and overrides site scoping. This role also has write access to OT devices by default.

## Procedure

1. From the Equipment Model Entities form, select a parent Equipment Model entity.  
   For information about equipment models, see [Managing equipment models](https://www.servicenow.com/docs/SxwQBPWdx~ZOHiVyDbjDQw "In the Industrial Workspace, you can review and manage ISA-95 equipment model data in the Equipment Model Manager. Review imported equipment model data or 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.
