Search for Operational Technology (OT) configuration items (CIs) and OT device information available in an OT CMDB table.
## Before you begin
* The Now Assist panel must be activated. For more information, see [Activate Now Assist panel standard chat](https://www.servicenow.com/docs/access?context=activate-now-assist-panel&version=yokohama&pubname=yokohama-intelligent-experiences&ft:locale=en-US).
* You must be assigned the now_assist_panel_user role to have access to the Now Assist panel.
* You must be assigned appropriate roles to search the relevant OT CMDB tables, such as cmdb_ot_viewer or cmdb_ot_isa_viewer.

## About this task
The OT CMDB search feature leverages the following:
* ServiceNow Otto for CMDB's Search CMDB agentic workflow
Important:
This agentic workflow is turned on by default. For more information, see [Now Assist skills, agents, and agentic workflows on by default](https://www.servicenow.com/docs/access?context=now-assist-skills-on-by-default&version=yokohama&pubname=yokohama-intelligent-experiences&ft:locale=en-US).
* ServiceNow AI Platform's Analytics Query Generator skill
Important:
This Now Assist skill is turned on by default. The skill will be automatically available to appropriate role users for the application. For more information, see [Now Assist skills, agents, and agentic workflows on by default](https://www.servicenow.com/docs/access?context=now-assist-skills-on-by-default&version=yokohama&pubname=yokohama-intelligent-experiences&ft:locale=en-US).

## Procedure
1. Select the Now Assist ![]() icon.
The Now Assist is displayed.
2. To initiate a search for OT CMDB tables, enter a prompt such as Search CMDB or CMDB Search.
The command signals that you want to search the CMDB tables.
3. Search for an OT device.
To optimize search results, include OT-specific trigger words or device types in your query, such as OT, Operational Technology, PLC, or HMI. Using relevant OT trigger words helps the CMDB search agentic workflow identify the OT context and display results in the Industrial Workspace.
For example, you can search for OT device information using prompts such as:
* Search for OT PLCs
* Search for OT network gear with Purdue Level 3
* Search for critical OT control systems

## Result
If there are less than five OT device records in the search results, then the agent lists the devices in the Now Assist panel. You can enter the OT device name for more information. The
agent
gives you the option to view the device in either a form view or a unified map.
Here are some examples of the form view.
Here are some examples of the unified map view.
When more than five OT device records appear in the search results based on your search criteria, you can select the link in the Now Assist panel (NAP) to view them. Here's an example of the OT PLC search results.
