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.

The nation's largest rotary heat-treating facility improves reliability, alarming, operator control, traceability, and data logging with groov EPIC.

When their PLCs began experiencing regular failures and the operating system of their HMI approached its end of life, American Metal Processing (AMP) knew it was "on borrowed time." In addition, the majority of system components were not integrated or automated beyond direct motor control. What was the best road to a modern system? How could the company achieve the data integrity, tracking, and connectivity required by their customers?

See how next-generation edge-based distributed I/O and controllers open new possibilities for connected infrastructure.

In the field of industrial automation, terms like digital transformation, the industrial internet of things (IIoT), or edge computing have become common topics of discussion. Today's businesses have IoT goals. End users need devices and applications to share data seamlessly across machines, sites, and the enterprise so they can optimize production and reduce costs. How do we achieve these goals?

Our MQTT series continues with a deep dive into groov EPIC’s (and now groov RIO’s) features for high-reliability MQTT networks.

At its heart, MQTT was designed for unreliable networks. Back in the ’90s, ConocoPhillips (now Phillips 66) was looking for a way to improve telemetry reporting over its low-bandwidth dial-up and costly VSAT (small satellite dish) SCADA network. IBM partnered with system integrator Arcom Control Systems (now Cirrus Link Solutions) to develop a minimalist communication protocol that could gracefully handle intermittent network outages and high latency among many distributed devices over TCP/IP.
