Your IoT middleware checklist

Posted by Matt Newton on Mar 2, 2017 8:00:00 AM

In a recent developer survey conducted by the Eclipse IoT Working Group, IEEE IoT, and Agile IoT, 40.8% of respondents indicated that the IoT solutions they were either currently building or planning to build are IoT platforms or IoT middleware.

Almost every large IT or OT company today has some form of IoT platform or middleware.

In fact, right now there are over 150 self-described IoT platforms in the market today. Not neccessarily created equally.

OptoNews: New version of Node-RED for groov Box

Posted by Jean Femia on Mar 1, 2017 4:02:04 PM

We've just released version 3 of Node-RED for the GROOV-AR1 groov Box. 

Node-RED is an open-source software tool for digitally wiring together hardware devices (like the groov Box), APIs (application program interfaces), and online services.

If you have a GROOV-AR1, Node-RED is included starting with groov Admin 44.

From IoT to IIoT: an industry pivot

Posted by Matt Newton on Feb 23, 2017 8:00:00 AM

This week Opto 22 is exhibiting at the Open IoT Summit in Portland, Oregon. The IoT Summit is a Linux Foundation event, packed with a ton of technology workshops and product demos.

We also exhibited at the IoT Summit last year. It’s a great chance to connect with the Linux developer community and get their perspective on things, since it’s so much different from what a typical industrial automation professional is exposed to.

The rise of the IoT middleware platform

Posted by Matt Newton on Feb 21, 2017 8:00:00 AM

In a recent developer survey conducted by the Eclipse IoT Working Group, IEEE IoT, and Agile IoT, 40.8% of respondents indicated the Internet of Things (IoT) solutions they were either currently building or planning to build were IoT platforms or IoT middleware.

Almost every large IT or OT company today has some form of IoT platform or middleware, with the current number of self-described IoT platforms exceeding 150.

OptoNews Tip: Top 4 tech tips from 2016

Posted by Jean Femia on Jan 4, 2017 3:39:10 PM

Did you miss any of these technical tips?

Now's a good time to review some automation basics—and look ahead to new technologies in our field.

Accuracy and resolution. Specifications for both of these are included for our analog modules. What's the difference?

Sinking and sourcing. What do these terms mean when you're wiring digital DC outputs, and which is the better way to wire? Lots of questions and answers on this one.

OptoNews Tip: Using Node-RED with Raspberry Pi

Posted by Jean Femia on Dec 14, 2016 3:56:38 PM

It's true: you can use your Raspberry Pi to monitor and control real-world industrial devices.

Reliable Opto 22 G4 digital I/O and SNAP digital I/O now work with your Pi. 

One of the simplest ways to program your Pi may be Node-RED, designed by IBM Emerging Technologies.

How to Build a Raspberry Pi with Node-RED and Industrial GPIO

Posted by Benson Hougland on Dec 14, 2016 3:39:17 PM

UPDATE: This post has been updated to reflect changes in the most recent Raspbian Jessie Lite image (no longer includes Node-RED or node.js) and to use the new Digital I/O for Raspberry Pi Starter Kit for I/O hardware (new code, photos, and video).

The Raspberry Pi® is an unquestionably powerful computer for just $35. And it really is just that: a computer. That means the Pi is capable of many tasks and perfect for many automation applications.

Couple the Pi to industrial, solid-state digital inputs and outputs, and you can build compelling and cost-effective solutions for commercial and industrial applications, too.

One of the easiest and fun ways to quickly build software applications is with Node-RED, the free, open-source software tool designed by IBM Emerging Technologies and used for wiring together hardware devices, APIs, and online services in new and interesting ways.

However, Node-RED is only included in the full PIXEL GUI version of the Raspbian Jessie Operating System, available from raspberrypi.org. Their latest 2016-11-25-raspbian-jessie-lite.img build for headless operation (no monitor, keyboard, or mouse required) is no longer bundled with either Node-RED or the required software tools node.js and npm.

The purpose of this post is to guide you through creating a headless Raspberry Pi computer with the latest versions of Node-RED, node.js, and npm, building a Node-RED application, and controlling and sensing GPIO connected to industrial digital I/O, quickly and simply. (For a sneak peek at the result of this build, see the video near the end of this post.)

OptoNews: IIoT tool Node-RED included in new groov Admin release

Posted by Jean Femia on Oct 26, 2016 3:11:05 PM

Just released! A major new tool for your Industrial Internet of Things (IIoT) project: the groov Box with Node-RED built in.

What is Node-RED?

It's an open-source, cross-platform tool for wiring together hardware devices, databases, cloud services, and APIs (application program interfaces) with simple logic flows.
