Server-side JavaScript for the IIoT

Posted by Matt Newton on Apr 6, 2017 8:00:00 AM

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.

OptoNews: Data center retrofit after 30 years

Posted by Jean Femia on Dec 14, 2016 3:58:11 PM
  • Think about how much computers have changed in the last 30 years.
  • Think about the quantity of data that enterprise data centers (EDCs) process today.
  • And think about how facility management priorities have changed to meet rising energy costs.

Now imagine what needs to be done to update a 30-year-old EDC.

OptoNews: New PAC REST API video - exchange data with Access database

Posted by Jean Femia on Dec 14, 2016 3:57:22 PM

In the last OptoNews, we showed you how an Excel® spreadsheet can exchange data with an Opto 22 SNAP PAC using the SNAP PAC controllers' RESTful API (application programming interface).

This time we'll show you how you can use the REST API with a Microsoft® Access® database.

OptoNews: New PAC REST API video - exchange data with Excel

Posted by Jean Femia on Nov 30, 2016 4:06:07 PM

What does the new built-in RESTful API in Opto 22 SNAP PAC S-series and R-series programmable automation controllers mean to you?

It means you can use a variety of programming languages to easily access data in the PAC.

OptoNews: Connecting industrial devices to IBM Watson IoT

Posted by Jean Femia on Oct 12, 2016 3:10:04 PM

You've heard about our Opto 22 SNAP PAC programmable automation controllers with their built-in RESTful API (application program interface).

The REST API gives you secure access to all the I/O point and variable data in the PAC.

Connect real-world industrial devices to IBM Watson IoT

Posted by Selam Shimelash on Sep 30, 2016 11:56:13 AM

If you've heard about our Opto 22 SNAP PACs with their built-in RESTful API (application program interface), you may be wondering how you'd use that API to send real-world data to the IBM Watson IoT platform.  

I'll show you how, step-by-step, in this blog post. It's a long post, but it includes everything you'll want to know. (You can print this page as a PDF if you like.)

OptoNews Tip: Peer-to-peer with REST

Posted by Jean Femia on Aug 31, 2016 4:25:57 PM

Here's the latest Code Samples and Tips contribution in our new OptoForum: an example of easier peer-to-peer communication between PAC controllers.

This example takes advantage of the new RESTful API in SNAP PAC hardware controllers (both the standalone S-series and the rack-mounted R-series).

How I upgraded my SNAP PAC controllers to version 9.5 and the RESTful interface

Posted by Benson Hougland on Aug 3, 2016 12:00:16 PM

I'm extremely excited about the new capabilities of the 9.5 firmware and, in particular, the new RESTful interface (REST API and HTTP/S server) for SNAP PAC controllers. I have several PACs throughout my home for various tasks like lighting, A/C, irrigation, energy management, monitoring, and surveillance. The new RESTful interface allows me to take my home automation system to completely new levels, including interacting with my other home automation/IoT products, like my Nest thermostats, smoke alarms, and NestCams; my Philips Hue lighting; my Wemo switches; and much more.

This post isn’t about home automation, however. It’s about getting the firmware upgrade done and configuring the HTTP/S RESTful server. And in doing so, it was important to me (and my application) that I preserved the persistent control system variables used in my control strategies. So...the following are the steps I took to upgrade my firmware while preserving important data and getting started with REST.
