Request-response vs. publish-subscribe, part 1: What's the diff?

Posted by Jean Femia on Feb 8, 2018 11:17:12 AM

We all know that computers and other electronic devices—printers, routers, laptops, smartphones, and more—are networked so they can exchange information.

But how does that information get where it’s supposed to go?

How does a spreadsheet get to the printer, a YouTube video get to your smartphone, or—most important for automation engineers—a value from a sensor get to your HMI?

New IoT Webinar: Live technologies demo

Posted by Jean Femia on Dec 7, 2017 11:18:56 AM

Is the Internet of Things (IoT) just a lot of hype, or can the IoT technologies we keep hearing about provide real value?

RESTful APIs, Node-RED, and MQTT are just some of the new technical terms we're all starting to learn.

If you'd like to see these technologies in action to understand how they might be useful for your applications, then join us for a new webinar on December 12.  

Opto 22's Senior Applications Engineer Kyle Orman will demo these technologies and more. He'll show you how to exchange live data between real-world I/O and IoT platforms. 

You'll see: 

- IoT hardware that's proven in industrial locations
- RESTful APIs to get data from PAC controllers
- Examples of simple logic flows created with Node-RED 
- Ignition Edge® OPC-UA drivers built into the  groov Box

IoT Certified OptoPartner integrates MES/ERP systems with automation

Posted by Jean Femia on Nov 20, 2017 11:09:24 AM

If you're a manufacturer interested in improving overall equipment effectiveness (OEE), you may find it difficult to integrate OEE with your manufacturing execution system (MES) or enterprise resource planning (ERP) system.

Why? Because the IT (information technology) software systems traditionally used for MES and ERP don't interface with the PLCs and I/O systems used in production and manufacturing.

Wine + IoT = yum + engineering fun

In my last post, I talked about beer and some hard deadlines at the end of a season. This time, let’s talk about wine and a different kind of season: harvest season!

During that Big Game, and since then, you might’ve seen some ads showing farmers in fields with iPads.

Well, I’ve met them.

Do we need anomaly detection, when we already have alarming?

Posted by Arun Sinha on Jul 20, 2017 5:05:58 PM

One of the main promises of the IIoT (Industrial Internet of Things) is advanced data analytics. As I research what exactly this means and look for use cases, one thing that comes up often is anomaly detection. At first glance, the question that comes to my mind is, "But wait, don’t we already have this?"

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.

OptoNews: SCADA system for smaller water/wastewater districts

Posted by Jean Femia on Apr 12, 2017 5:13:08 PM

When you're a smaller water/wastewater treatment district, it can be difficult to fund the SCADA systems you need.

All water/wastewater operations have to be strictly monitored and their data stored for reference, no matter the size of the district.
