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.

The Industrial Internet of Things (IIoT) is coming at us fast. Big players like Dell, IBM, and Amazon are entering industrial markets and creating disruption among the typical market vendors. And with these new players comes a variety of technologies that are being applied in new and interesting ways to build the IIoT.
Over the next several blog posts, we’ll be discussing the top 5 software technologies and languages that systems integrators and automation engineers should begin learning about to be ready to build Industrial Internet of Things applications. Sign up for the blog to get access to followup blog posts as they’re released.
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.

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.

One Ethernet network troubleshooting tool our Product Support Group recommends is Wireshark. It's been a helpful choice for many years, and it's free.
Our recent blog post explains where to get Wireshark and how to use it. You can pay a lot for network analysis tools—and in some cases you may need them—but many times, the free ones do the job.
