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.
