Opto 22 SNAP PAC controllers and brains both have two Ethernet network interfaces—pretty handy. But do you use them the same way? That's the question we'll answer in this tech tip.
Most devices used on an Ethernet network have one network interface with an RJ-45 connector. But SNAP PAC controllers and EB brains each have two interfaces—two RJ-45 connectors.
However, the two interfaces on controllers and brains are designed for different uses.

As the IIoT continues its widespread adoption, a lot of new IT technologies are quickly being adopted by the industrial automation and process control industries. More and more, industrial assets are becoming Internet enabled and being connected to other digital systems.
Monitoring OEE and KPIs in real time from a mobile device is no longer a pie-in-the-sky application. It’s happening right now, through the convergence of OT and IT.
One of the technologies that’s enabling the IIoT is secure digital communication. And to establish that secure communication, you need to have an authority you can trust that can validate the indentity of devices on a network and on the Internet. You have to trust that the encrypted connection you're using is actually connected to the device you want to talk to, and not to some rogue node trying to breach your network and steal your information.
That’s where Certificate Authorities come into play in the IIoT.

In a previous post we introduced JavaScript and discussed its widespread adoption as a result of its interoperability between web applications, particularly browsers.
In this post we’re going to tackle some ideas related to why JavaScript is poised to literally take over the Industrial Internet of Things as the software language of choice for IIoT developers.
We’ll also discuss why, if you’re an industrial automation engineer starting to think about the IIoT, it might be a good idea to brush up on your JavaScript skills.

In one of our previous blog posts we talked about AC motors, the workhorse of modern industrial automation. We learned how they use magnets, electromagnets, and magnetic fields to generate huge amounts of torque to run our industrial processes.
To understand how modern motor control works, let’s take a closer look at how a 3-phase AC induction motor works.

If you're using Node-RED and the nodes for SNAP PACs and groov—or if you're thinking about it but haven't started—check out our new Node-RED examples on developer.opto22.com.
Node-RED is the open-source tool for digitally wiring together hardware devices, cloud services, databases, and more in simple logical flows.

Have you tried AT&T's Internet of Things (IoT) platform, M2X?
If you're looking at IoT platforms, you'll want to see this new technical note. It shows you how to get real-world data, in this example a temperature in degrees F, to an AT&T M2X device in the cloud.

In a previous blog post we covered what ransomware is and how it’s being used to target industrial users like water and wastewater SCADA systems.
Ransomware is basically when a hacker obtains control of your data, or even your control network and automation systems, and won’t relinquish control back to you until a ransom is paid.
It's a major potential threat against IIoT applications.
When most people think about cyber security, they probably conjure up thoughts of someone locked away in a dark room, wearing the same grey hoodie for months. Staring at a screen for days at a time looking for just the right network packet to tell them where and how to attack. But that's not always how hacking is done.

Most people relate the term blockchain to an Internet currency or peer-to-peer payment system called Bitcoin.
But there’s way more value to blockchain technology than just a payment system.
And it just might help us solve a lot of problems related to industrial cyber security, particularly in Industrial Internet of Things applications.

Sure, the industrial Internet of Things sounds cool. Real cool, in fact. But how do you do it and where do you get started?
For a self-proclaimed technology geek like myself, the industrial Internet of things (IIoT) is a pretty exciting topic. I wasn’t exactly born digital (individuals who have grown up with the current state of ubiquitous computing and communications).
