Querying industrial belongings utilizing pure language with AWS IoT SiteWise and Brokers for Amazon Bedrock


Generative AI-powered chatbots are driving productiveness positive factors throughout industries by offering on the spot entry to info from numerous information sources, accelerating decision-making, and decreasing response occasions. In fast-paced industrial environments, course of engineers, reliability consultants, and upkeep personnel require fast entry to correct, real-time operational information to make knowledgeable choices and keep optimum efficiency. Nevertheless, querying complicated and sometimes siloed industrial techniques like SCADA, historians, and Web of Issues (IoT) platforms will be difficult and time-consuming, particularly for these with out specialised data of how the operational information is organized and accessed.

Generative AI-powered chatbots present pure language interfaces to entry real-time asset info from disparate operational and company information sources. By simplifying information retrieval by conversational interactions, generative AI allows operators to spend much less time gathering information and extra time optimizing industrial productiveness. These user-friendly chatbots empower personnel throughout roles with invaluable operational insights, streamlining entry to crucial info scattered all through operational and company sources.

Implementing chatbots in industrial settings requires a software to help a big language mannequin (LLM) in navigating structured and unstructured information from industrial information shops to retrieve related info. That is the place generative AI-powered brokers come into play. Brokers are AI techniques that use an LLM to know an issue, create a plan to resolve it, and execute that plan by calling APIs, databases, or different sources. Brokers act as an interface between customers and sophisticated information techniques, enabling customers to ask questions in pure language without having to know the underlying information representations. For instance, store ground personnel might ask a few pump’s peak revolutions per minute (RPM) within the final hour with out figuring out how that information is organized. Since LLMs can not carry out complicated calculations instantly, brokers orchestrate offloading these operations to industrial techniques designed for environment friendly information processing. This enables finish customers to get pure language responses whereas leveraging current information platforms behind the scenes.

On this weblog publish, we are going to information builders by the method of making a conversational agent on Amazon Bedrock that interacts with AWS IoT SiteWise, a service for accumulating, storing, organizing, and monitoring industrial tools information at scale. By leveraging AWS IoT SiteWise’s industrial information modeling and processing capabilities, chatbot builders can effectively ship a strong answer to allow customers throughout roles to entry crucial operational information utilizing pure language.

Resolution Overview

By leveraging Brokers for Amazon Bedrock, we are going to construct an agent that decomposes person requests into queries for AWS IoT SiteWise. This enables accessing operational information utilizing pure language, with out figuring out question syntax or information storage. For instance, a person can merely ask “What’s the present RPM worth for Turbine 1?” with out utilizing particular instruments or writing code. The agent makes use of the contextualization layer in AWS IoT SiteWise for intuitive representations of commercial sources. See How AWS IoT SiteWise works for particulars on useful resource modeling.

system architecture

From a chatbot interface, the person asks a pure language query that requires entry to industrial asset information. The agent makes use of the OpenAPI specification (merchandise 1) to orchestrate a plan for retrieving related information. It leverages an motion group defining queries the agent can carry out (merchandise 2), dealt with by an AWS Lambda operate that makes use of the AWS IoT SiteWise ExecuteQuery API (merchandise 3). The agent could invoke a number of actions to execute the LLM’s plan till acquiring obligatory information, e.g., querying property names, deciding on the matching title, then querying latest measurements. As soon as offered the requested operational information, the mannequin composes a solution to the unique query (merchandise 4).

Constructing the Agent


  1. This answer leverages Brokers for Amazon Bedrock. See Supported areas and fashions for a present listing of supported areas and basis fashions. To allow entry to Anthropic Claude fashions, you’ll need to allow Mannequin entry in Amazon Bedrock. The agent described on this weblog was designed and examined for Claude 3 Haiku.
  2. The agent makes use of the SiteWise SQL engine, which requires that AWS IoT SiteWise and AWS IoT TwinMaker are built-in. Please observe these steps to create an AWS IoT TwinMaker workspace for AWS IoT SiteWise’s ExecuteQuery API.
  3. The supply code for this agent is obtainable on GitHub.

To clone the repository, run the next command:

git clone

Step 1: Deploy AWS IoT SiteWise belongings

On this agent, AWS IoT SiteWise manages information storage, modeling, and aggregation, whereas Amazon Bedrock orchestrates multi-step actions to retrieve user-requested info. To start, you’ll need actual or simulated industrial belongings streaming information into AWS IoT SiteWise. Observe the directions on Getting began with AWS IoT SiteWise to ingest and mannequin your industrial information, or use the AWS IoT SiteWise demo to launch a simulated wind farm with 4 generators. Be aware that the directions on step 3 and the pattern questions in step 4 had been ready for the simulated wind farm and, if utilizing your personal belongings, you’ll have to put together your personal agent directions and take a look at questions.

Step 2: Outline the motion group

Earlier than creating an agent in Amazon Bedrock, you might want to outline the motion group: the actions that the agent can carry out. This motion group will specify the person queries the agent could make to AWS IoT SiteWise whereas gathering required information. An motion group requires:

  • An OpenAPI schema to outline the API operations that the agent can invoke
  • A Lambda operate that can take the API operations as inputs

Step 2.1: Design the OpenAPI specification

This answer supplies API operations with outlined paths that describe actions the agent can execute to retrieve information from latest operations. For instance, the GET /measurements/{AssetName}/{PropertyName} path takes AssetName and PropertyName as parameters. Be aware the detailed description that informs the agent when and how one can name the actions. Builders can add related paths to the schema to incorporate actions (queries) related to their use circumstances.

  "paths": {
    "/measurements/{AssetName}/{PropertyName}": {
      "get": {
        "abstract": "Get the newest measurement",
        "description": "Primarily based on offered asset title and property title, return the newest measurement obtainable",
        "operationId": "getLatestMeasurement",
        "parameters": [
            "name": "AssetName",
            "in": "path",
            "description": "Asset Name",
            "required": true,
            "schema": {
              "type": "string"
            "name": "PropertyName",
            "in": "path",
            "description": "Property Name",
            "required": true,
            "schema": {
              "type": "string"

Add the openapischema/iot_sitewise_agent_openapi_schema.json file with the OpenAPI specification to Amazon S3. Copy the bucket and path as a result of we’re going to want that in step 3.

Step 2.2: Deploy the AWS Lambda operate

The agent’s motion group shall be outlined by an AWS Lambda operate. The repository comes with a template to routinely deploy a serverless software constructed with the Serverless Software Mannequin (SAM). To construct and deploy, clone the GitHub repository and run the next instructions from the principle listing, the place the template.yaml file is saved.

sam construct --use-container
sam deploy --guided

Observe the directions from the immediate to finish the deployment.

The lambda_handler operate will learn the API path from the invocation, and can name one of many following features relying on the request. See the instance beneath for the motion outlined for the /measurements/{AssetName}/{PropertyName} path, which calls the get_latest_value operate the place we use the SiteWise ExecuteQuery API to pick out the newest observations for a person outlined property. Discover that actions will be outlined to return profitable and unsuccessful HTTP standing codes, and that the agent can use the error code to proceed the dialog and immediate the person for clarification.

def lambda_handler(occasion, context):
    responses = []
        api_path = occasion['apiPath']
        logger.information(f'API Path: {api_path}')
        physique = ""
        if api_path == "/measurements/{AssetName}/{PropertyName}":
            asset_name = _get_named_parameter(occasion, "AssetName")
            property_name = _get_named_parameter(occasion, "PropertyName")
                physique = get_latest_value(sw_client, asset_name, property_name)
            besides ValueError as e:
                return {
                    'statusCode': 404,
                    'physique': json.dumps({'error': str(e)})

Builders taken with increasing this agent can create new strategies within the Lambda operate to make their queries to the IoT SiteWise ExecuteQuery API, and map these strategies to new paths. The ExecuteQuery API permits builders to run complicated calculations with present and historic information, which might embrace aggregates, worth filtering, and metadata filtering.

Step 3: Construct the agent with Brokers for Amazon Bedrock

Go to the Amazon Bedrock console, click on on Brokers underneath Orchestration, after which click on on Create Agent. Give your agent a significant title (e.g., industrial-agent) and choose a mannequin (e.g., Anthropic – Claude 3 Haiku).

Crucial half within the agent definition are the agent directions, which can inform the agent of what it ought to do and the way it ought to work together with customers. Some finest practices for agent directions embrace:

  • Clearly defining function and capabilities upfront.
  • Specifying tone and ritual stage.
  • Instructing how one can deal with ambiguous or incomplete queries (e.g., ask for clarification).
  • Guiding how one can gracefully deal with out-of-scope queries.
  • Mentioning any particular area data or context to think about.

Should you deployed the wind generators simulation from AWS IoT SiteWise in step 1, we advocate the next directions. Do not forget that agent directions are not optionally available.

You might be an industrial agent that helps operators get the newest measurement obtainable from their wind generators. You’re going to give responses in human-readable type, which suggests spelling out dates. Use clear, concise language in your responses, and ask for clarification if the question is ambiguous or incomplete. If no clear instruction is offered, ask for the title of the asset and the title of the property whose measurement we wish to retrieve. If a question falls exterior your scope, politely inform the person

Underneath Motion Teams, choose the Lambda operate you created in step 3, and browse or enter the S3 URL that factors to the API schema from step 2.1. Alternatively, you may instantly enter the textual content from the API schema on the Bedrock console.

Go to Assessment and create.

Step 4: Take a look at the agent

The Amazon Bedrock console permits customers to check brokers in a conversational setting, view the thought course of behind every interplay, and make the most of Superior prompts to change the pre-processing and orchestration templates routinely generated within the earlier step.

Within the Amazon Bedrock console, choose the agent and click on on the Take a look at button. A chat window will pop up.

Attempt the agent to ask questions corresponding to:

  • What wind turbine belongings can be found?
  • What are the properties for Turbine 1?
  • What’s the present worth for RPM?

Discover that the agent can cause by the information from SiteWise and the chat historical past, usually understanding the asset or property with out being given the precise title. For example, it acknowledges Turbine 1 as Demo Turbine Asset 1 and RPM as RotationsPerMinute. To perform this, the agent orchestrates a plan: listing obtainable belongings, listing properties, and question based mostly on the asset and property names saved in SiteWise, even when they don’t match the person’s question verbatim.

Q&A interaction testing the agent

The response given by the agent can at all times be tuned. By clicking the Present hint button, you may analyze the decision-making course of and perceive the agent’s reasoning. Moreover, you may modify the agent’s habits by utilizing Superior prompts to edit the pre-processing, orchestration, or post-processing steps.

As soon as assured in your agent’s efficiency, create an alias on the Amazon Bedrock console to deploy a draft model. Underneath Agent particulars, click on Create alias to publish a brand new model. This enables chatbot purposes to programmatically invoke the agent utilizing InvokeAgent within the AWS SDK.
