OptoNews Tip: Choosing the right SNAP I/O module

Posted by Jean Femia on Jun 12, 2017 8:50:54 AM

Maybe you're monitoring temperature, or controlling a production line, or getting data from a load cell. Whatever your goal, you want to get the I/O that works best for your application. 

Or maybe you happen to notice we have more than one SNAP-AIV voltage input module and wonder how they're different. 

Here are a couple of ways to find a SNAP module with the features you need and compare similar modules.

2017 Automation Conference: IoT doesn't always mean Internet

Posted by Matt Newton on Jun 1, 2017 2:57:59 PM

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.

OptoNews Tip: Compare SNAP PAC controllers and brains

Posted by Jean Femia on May 23, 2017 4:06:48 PM

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.

A Survey of Big Data Analytics Software

Posted by Matt Newton on May 18, 2017 8:09:57 AM

In a previous post we covered time series data.

We talked about how process automation and control data can feed our big data applications and cloud-based software platforms, to build Industrial Internet of Things applications.

In this post we'll take a look at how time series data can be used to develop time series models.

WannaCry Ransomware. Is Your SCADA Network At Risk?

Posted by Matt Newton on May 16, 2017 8:00:00 AM

Undoubtedly you’ve heard of the most recent ransomware attack plaguing the globe. It started late last week and so far has infected machines across 150 countries.

As the name suggests, the virus in effect holds the infected computer hostage and demands that the victim pay a ransom in order to regain access to the files on his or her computer. You can learn more about ransomware in this previous blog post.

But let’s get down to what you need to know. Here are the latest facts about WannaCry that you need to be aware of to make sure your systems are not at risk.

OptoNews Tip: Choosing an SSR for your application

Posted by Jean Femia on May 15, 2017 12:27:13 PM

Over 40 years ago, Opto 22 started manufacturing solid state relays (SSRs). With the wide variety we've built over the years, we probably have the SSR you need in stock right now. 

We also have some advice on choosing and running SSRs in specific applications.

Predictive Analytics from Process Control Data

Posted by Matt Newton on May 11, 2017 9:05:28 AM

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.

EdgeX Connects OT to IT

Posted by Matt Newton on May 9, 2017 9:12:10 AM

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.
