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.

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.

This is the first post in a series of upcoming posts on Industrial Automation 101 topics.
These posts are geared towards people new to the industry who are looking for basic information on how some of the gear in the industrial automation field works, when to use it, and maybe even how to troubleshoot it here and there.

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.

What could cognitive computing do for you?
Cognitive computing involves analyzing huge quantities of data and spotting correlations and patterns that are valuable—similar to what a human brain can do. But computers can analyze lots more data, much faster.
