Securely Ingest Industrial Data to AWS via Machine to Cloud Solution
As a manufacturing enterprise, maximizing your operational efficiency and optimizing output are critical factors in this competitive global market. However, many manufacturers are unable to frequently collect data, link data together, and generate insights to help them optimize performance. Furthermore, decades of competing standards for connectivity have resulted in the lack of universal protocols to connect underlying equipment and assets.
Machine to Cloud Connectivity Framework (M2C2) is an Amazon Web Services (AWS) Solution that provides the secure ingestion of equipment telemetry data to the AWS Cloud. This allows you to use AWS services to conduct analysis on your equipment data, instead of managing underlying infrastructure operations. The solution allows for robust data ingestion from industrial equipment that use OPC Data Access (OPC DA) and OPC Unified Access (OPC UA) protocols.
Secure, automated configuration and ingestion of industrial data
M2C2 allows manufacturers to ingest their shop floor data into various data destinations in AWS. These include AWS IoT SiteWise, AWS IoT Core, Amazon Kinesis Data Streams, and Amazon Simple Storage Service (S3). The solution is integrated with AWS IoT SiteWise so you can store, organize, and monitor data from your factory equipment at scale. Additionally, the solution provides customers an intuitive user interface to create, configure, monitor, and manage connections.
Automated setup and configuration
Figure 1. Automatically create and configure connections
With M2C2, you can connect to your operational technology assets (see Figure 1). The solution automatically creates AWS IoT certificates, keys, and configuration files for AWS IoT Greengrass. This allows you to set up Greengrass to run on your industrial gateway. It also automates the deployment of any Greengrass group configuration changes required by the solution. You can define a connection with the interface, and specify attributes about equipment, tags, protocols, and read frequency for equipment data.
Figure 2. Send data to different destinations in the AWS Cloud
Once the connection details have been specified, you can send data to different destinations in AWS Cloud (see Figure 2). M2C2 provides capability to ingest data from industrial equipment using OPC-DA and OPC-UA protocols. The solution collects the data, and then publishes the data to AWS IoT SiteWise, AWS IoT Core, or Kinesis Data Streams.
Publishing data to AWS IoT SiteWise allows for end-to-end modeling and monitoring of your factory floor assets. When using the default solution configuration, publishing data to Kinesis Data Streams allows for ingesting and storing data in an Amazon S3 bucket. This gives you the capability for custom advanced analytics use cases and reporting.
You can choose to create multiple connections, and specify sites, areas, processes, and machines, by using the setup UI.
Management of connections and messages
Figure 3. Manage your connections
M2C2 provides a straightforward connections screen (see Figure 3), where production managers can monitor and review the current state of connections. You can start and stop connections, view messages and errors, and gain connectivity across different areas of your factory floor. The Manage connections UI allows you to holistically manage data connectivity from a centralized place. You can then make changes and corrections as needed.
Architecture and workflow
Figure 4. Machine to Cloud Connectivity (M2C2) Framework architecture
The AWS CloudFormation template deploys the following infrastructure, shown in Figure 4:
- An Amazon CloudFront user interface that deploys into an Amazon S3 bucket configured for web hosting.
- An Amazon API Gateway API provides the user interface for client requests.
- An Amazon Cognito user pool authenticates the API requests.
- AWS Lambda functions power the user interface, in addition to the configuration and deployment mechanism for AWS IoT Greengrass and AWS IoT SiteWise gateway resources. Amazon DynamoDB tables store the connection metadata.
- An AWS IoT SiteWise gateway configuration can be used for any OPC UA data sources.
- An Amazon Kinesis Data Streams data stream, Amazon Kinesis Data Firehose, and Amazon S3 bucket to store telemetry data.
- AWS IoT Greengrass is installed and used on an on-premises industrial gateway to run protocol connector Lambda functions. These connect and read telemetry data from your OPC UA and OPC DA servers.
- Lambda functions are deployed onto AWS IoT Greengrass Core software on the industrial gateway. They connect to the servers and send the data to one or more configured destinations.
- Lambda functions that collect the telemetry data write to AWS IoT Greengrass stream manager streams. The publisher Lambda functions read from the streams.
- Publisher Lambda functions forward the data to the appropriate endpoint.
Data collection
The Machine to Cloud Connectivity solution uses Lambda functions running on Greengrass to connect to your on-premises OPC-DA and OPC-UA industrial devices. When you deploy a connection for an OPC-DA device, the solution configures a connection-specific OPC-DA connector Lambda. When you deploy a connection for an OPC-UA device, the solution uses the AWS IoT SiteWise Greengrass connector to collect the data.
Regardless of protocol, the solution configures a publisher Lambda function, which takes care of sending your streaming data to one or more desired destinations. Stream Manager enables the reading and writing of stream data from multiple sources and to multiple destinations within the Greengrass core. This enables each configured collector to write data to a stream. The publisher reads from that stream and sends the data to your desired AWS resource.
Conclusion
Machine to Cloud Connectivity (M2C2) Framework is a self-deployable solution that provides secure connectivity between your technology (OT) assets and the AWS Cloud. With M2C2, you can send data to AWS IoT Core or AWS IoT SiteWise for analytics and monitoring. You can store your data in an industrial data lake using Kinesis Data Streams and Amazon S3.
