Opto 22's Node-RED expert Terry Orchard shares a new series of videos for developers to help get the most out of your groov RIO.

Our Node-RED videos continue to be one of the most watched series on our website and YouTube channel. Included in both groov EPIC and groov RIO, Node-RED is an open-source software program used to wire together devices, databases, cloud applications, and APIs (application program interfaces) with simple logic flows. It's growing in popularity, and engineers, programmers, and developers are hungry to learn more.

This latest video in our Automation 101 series provides a deeper dive and explanation of the MQTT central server, or the "broker".

As you recall from previous posts, the industrial MQTT communication protocol is a powerful tool that allows you to exchange device data freely among devices and applications, with little or no IT involvement. Its simplicity and flexibility make it a popular choice for today's IIoT applications.

The web has transformed the way engineers, technicians, and plant managers find, select, and buy industrial automation, instrumentation, and controls.

I recently binge-watched the series "Halt and Catch Fire" on Netflix. It’s a fictional but historically based drama about the rise of the personal computing industry starting in the mid 1970s and running through to the internet age.

It was really interesting, especially for those of us who lived through it, or some of it (I started college in 1985). Not to mention the great soundtrack, if you like 1980’s punk, new wave, and alternative music!

• How do you get machine data without interfering with the process? 
• What's an easy way to monitor temperature in a server room?
• How can you control the flow of heating and cooling water in your HVAC system?

These are the kinds of fundamental questions that come up over and over in automation applications, and our new Automation 101 video series aims to answer them.

• 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.

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.
