Creating a data stream from NIST manufacturing lab data – Part 1

The Industry Experiences team has recently published a solution guide for extracting insights from existing IoT data. The solution consists of the following high-level components.

Ingest data Hot path processing Cold path processing Analytics clients

This is the first of a series of blogs that go through those components in detail. We start with ingesting data into the solution and creating a data stream.

The NIST data

The solution uses the data published by US National Institute of Standards and Technology Smart Manufacturing Systems test bed that exposes the manufacturing lab’s data. We use the data from the lab’s volatile data stream (VDS).

The VDS is implemented using the MTConnect standard. The standard offers a semantic vocabulary for manufacturing equipment. It defines a protocol to communicate with an MTConnect agent and the schema for the data returned.

The agent and its methods

The agent exposes an HTTP endpoint that supports the following API operations:

probe: Returns the list of devices, components, subcomponents and data items. current: Returns a snapshot of the data item’s most recent values or the state of the device at a point in time. sample: Returns Samples, Events and Condition in time series. asset: Most recent state




IoT solutions for manufacturing: build or buy?
IoT solutions for manufacturing: build or buy?

If you are a manufacturer who wants to take its first steps towards IoT, and you’re overwhelmed by the plethora of vendors and IoT platforms in the IoT space, you are not alone. IoT is still a new space, with many moving parts and products. This makes it hard for organizations to know exactly where and how to get started. In this blog, I will try to provide you a simplified overview and next steps, based on the conversations I have been having with many manufacturing organizations.

Components of an IoT solution

When it comes to deciding whether to build or buy your IoT solution it is important, of course, to understand exactly what you are building or buying. To that end, it helps to identify the main components of an IoT solution stack (Figure 1). From bottom to top:

Gaining insights from industrial IoT data with Microsoft Azure

Technology is moving at an amazing pace. Manufacturers around the world are observing this first-hand. Additive manufacturing, robotics, and IoT are some of the technologies that directly influence the way manufacturing businesses operate. The manufacturing industry is not isolated from the huge leaps in computer technology. Software packages used for managing complex processes and fabrication machine tools (for example, Computer numerical control milling and CNC turning) are everywhere and are generating huge amounts of data.

I have heard from many customers in the manufacturing industry that they are not sure what steps they need to take to gain insights from all the data they have.

My recommendation is to start small. Do not make big investments right at the start, but first discover what can be gained from the available choices. Then bring it into a platform that can provide many other possibilities, such as machine learning and AI. The Azure platform features many application services. But important to manufacturers, Azure gives access to hardware resources, such as faster CPUs, field programmable gate arrays (FPGA), and graphics processing units (GPU) — all are easily accessible for state-of-the-art solutions.

What is starting small? What is possible? While seeking answers to

A powerful and intuitive way to route device messages in Azure IoT Hub

Azure IoT Hub message routing simplifies IoT solution development and enables you to send messages from your devices to cloud services in an automated, scalable, and reliable manner. You can also use routing queries to apply customized filters and send only the most relevant data to the service facing endpoints.

We are announcing a new capability in message routing that allows you to query on the device twin tags and properties, in addition it allows you to query on message properties and message body, which has been previously available. Moreover, the new Azure portal experience for message routing delivers simpler navigation between routes and endpoints making it an even better experience.

IoT solutions involve sending large amounts of device telemetry data that can rapidly become overwhelming. The new message routing capabilities in IoT Hub make it even more powerful and easier to set up automatic routes for messages from devices, implementing advanced filtering and sending huge amounts of data in real time. For example, if you are developing a connected factory solution, where you want to send data based on different device types such as motors and chillers to different services for computation of utilization and failure rates. You can

Extended offline operation with Azure IoT Edge
Extended offline operation with Azure IoT Edge

We recently announced the general availability of Azure IoT Edge, allowing you to deploy cloud workloads like AI and machine learning to run directly on your IoT devices. Now devices can act immediately on real-time data—whether it be recognizing a crack in a pipe from an aerial view or predicting equipment failure before it happens.

We are taking the next step to ensure our customers’ IoT solutions operate reliably in remote locations and harsh conditions—where cloud connectivity is intermittent at best. Today, we are happy to announce extended offline operation for Azure IoT Edge, now in public preview.

Existing capabilities have been enhanced with device restart and device-to-device communication even when disconnected from the cloud. After a one-time sync between the edge device and Azure IoT Hub, the edge device can function in offline mode indefinitely.

When using an edge device as a transparent gateway, we are releasing a new portal experience for assigning IoT devices as children of the gateway. Assigned children can connect and communicate with their parent or siblings even when there is no Azure IoT Hub connectivity.

These new features deliver frequently requested functionality by customers as a number of real-world scenarios require the power of




Remote Monitoring Solution allows for root cause analysis with Azure Time Series Insights

With the abundance of data coming from IoT devices and the global nature of business today, it’s essential to be able to understand correlations and track historical trends across your assets.

Imagine managing a fleet of trucks carrying items that need to be maintained at a specific temperature. Occasionally you see a low temperature alert triggered for some of your trucks during their daily scheduled delivery. As an operator, you will need to conduct a root cause analysis to understand why this is happening, if there are recurring patterns, and how to prevent it from happening in the future.

To help you with this, we’re excited to announce that we have now integrated Azure Time Series Insights into the Azure IoT Remote Monitoring solution accelerator. With Time Series Insights, you can gain deeper insights into your time-series sensor data by spotting trends, anomalies, and correlations across real-time and historical data in all your locations. New Remote Monitoring deployments (both Basic and Standard) will include Time Series Insights out-of-the-box* at no extra cost.

Describe, diagnose, and predict with IoT Analytics

In a previous blog article Extracting actionable insights from IoT data I discuss the value of collecting IoT data from machines, assets and products. The whole point of collecting IoT data is to extract actionable insights. Insights that will trigger some sort of action that will result in some business value such as optimized factory operations, improved product quality, better understanding of customer demand, new sources of revenue, and improved customer experience.

In this blog, I discuss the extraction of value out of IoT data by focusing on the analytics part of the story.

Generally speaking, data analytics comes in four types (Figure 1):

Descriptive, to answer the question: What’s happening? Diagnostic, to answer the question: Why’s happening? Predictive, to answer the question: What will happen? Prescriptive, to answer the question: What actions should we take?
