Last week Opto 22 exhibited at the Automation Conference in Chicago. It was a great event, with a lot of interesting material presented and some really cool new technology demonstrated.
I conducted two workshops for attendees while I was there, both on Rapid IIoT Application Development with Node-RED, RESTful APIs, and MQTT.

It's easy to get confused between Opto 22 SNAP PAC controllers and SNAP PAC brains.
They're both intelligent processors for automation, some of them look alike, and there's even overlap in what some of them do.
Let's take a look at how SNAP PAC controllers and brains are similar and how they're different.
The holy grail of IIoT applications is the ability to basically predict the future.
We want to know when something, either a system or a component in our process is going to fail—before it actually does.

What is the core concept of edge computing? It's to establish data connectivity and filtering between the devices at the network edge that generate big data, and the systems in the cloud that need to consume that data for machine learning, predictive analytics, and so on.
In several previous posts we discussed the EdgeX project from The Linux Foundation. We saw how its microservices are designed to collect data from industrial devices and systems and then move that data from the local network to the cloud.
In this post we’ll focus on how that final step of transferring real-world data from our industrial assets to the cloud actually happens—through the Export Services layer of EdgeX.

In our last post we covered how Core Services in the new EdgeX project from the Linux Foundation help engineers quickly build edge computing and IIoT applications. Core Services are the microservices EdgeX provides to convert physical electrical signals from industrial devices into digital information.
In this post, we’ll focus on how EdgeX makes digital data from industrial assets available to higher-level computing systems like predictive analytics and machine learning.
But before the data is made available to those systems, EdgeX uses what it calls Supporting Microservices to do some pretty high-tech stuff to package the data and make it easily accessible.

In a previous post we covered EdgeX and its important role in building a standard platform for connecting edge computing systems, like Opto 22 SNAP PAC automation controllers, to the industrial Internet of Things (IIoT).
EdgeX connects OT and IT assets together, bridging between the physical world and the digital world through a loosely coupled microservice platform architecture. These microservices provide OT and IT devices, software, and services with a platform that provides connectivity and communications methods.

There’s an African proverb that says if you want to go fast, go alone; if you want to go far, go together.

One of the biggest questions companies face when surveying IIoT (Industrial Internet of Things) technology is where to invest. The IIoT can be a pretty foggy and technologically diverse topic for anyone to understand. And there are so many competing standards out there today that it’s tough to identify which path to take.
But a new platform built upon an open source, extensible framework for IIoT technology called EdgeX was recently announced, and it may be just what the industry needs to part the clouds of confusion and shine some clarity on the IIoT.

In several previous posts we talked about some of the software technologies automation professionals should put on their radar in preparation for Industrial Internet of Things (IIoT) applications.
JavaScript, node.js and Node-RED offer a ton of benefits to those looking to build their IIoT application. Learn more about the Industrial Internet of Things in the State of the IIoT white paper.

In a previous post, we discussed server-side JavaScript and its use case in IIoT applications. Before server-side JavaScript, applications were written in one language for server-side software and a completely different language for client-side software.
This split complicated application development, because it required having two sets of software developer talents—or even two separate software developers or teams—one for client-side and one for server-side application development.
Server-side JavaScript and the node.js runtime environment have solved this problem.
