Learn and experiment with your own updated groov EPIC Learning Center 2

The new groov EPIC Learning Center 2 is in production now—and it includes even more features and capabilities than the original! See what's included in the new GRV-EPIC-LC2, and be ready to take on your industrial automation and IIoT applications.

A complete package of fully functioning EPIC hardware and software, the groov EPIC Learning Center is designed as an integral part of our free OptoU Online Training at training.opto22.com.

So what's new this time around?

This tech tip post covers some groov Manage tools that make the Opto Memory Map Protocol easier to use.

The Opto Memory Map Protocol (OptoMMP) is a powerful method of interacting with Opto controllers, everything from a PAC brain to the latest groov RIO—however, it's often overlooked and underused. This blog post covers some tools built right in to groov Manage that make OptoMMP more approachable, easier to implement, and straightforward to debug.

In this week's edition of our 12-part groov Manage journey, we take a look at Node-RED. This low-code/no-code programming tool is a popular feature of groov EPIC and groov RIO.

Our engineers love all aspects of technology, so it's no surprise to learn that many of them were tinkering with Node-RED at home before bringing their excitement to work.  After some roundtable discussions on just how much Javascript coding was required (hint: as little or as much as you want), we decided to embed Node-RED into our product range and future hardware devices.

Watch groov Manage: Node-RED to see why Node-RED is so popular with groov EPIC and RIO customers.

With the latest groov 3.5 firmware update comes another new version of Node-RED, its 3.0 milestone release.

Get ready to see what's new in Node-RED when you update to groov EPIC 3.5. This new version includes all the additions of the 3.0.2 software, the most recently available at the time of writing, and node v14.20.0 and npm 6.14.17 package updates as well. Let's take a look.

New video shows how to access data no matter where your Node-RED server is running.

The Node-RED how-to video series continues with some tips on using certificates. Recent videos in the series covered why you should run Node-RED on groov devices, and how to install and configure Opto 22 Node-RED packages for PAC Control, groov I/O and groov View.

Now Terry Orchard is back at the demo desk to show you how to use both self-signed and Certificate Authority certificates to help move data between groov RIO and EPIC, no matter where your Node-RED server is running.

Using powerful built-in software, it’s easy to add more functionality to the multifunction, mixed signal I/O on groov RIO, including using RTD temperature probes with minimal code.

The groov RIO MM1, MM2, and even the groov EPIC GRV-MM1001-10 modules are extremely flexible, with an incredible number of software configurable options. Even with all that potential, you can do more when you combine this I/O with software tools like PAC Control, CODESYS, Node-RED, and custom Linux programs.

A great way to see this is with RTD sensors.

The Node-RED package video series wraps up with a closer look at groov View nodes.

If you've been following the OptoBlog, you've noticed we have a new series of Node-RED videos dedicated to explaining all the Opto 22 Node-RED packages available for your groov EPIC or RIO device. The last video in this 5-part series is now available.

Terry Orchard is back in the OptoStudio to explain groov View nodes. You'll learn about Read and Write, review how the nodes are configured, and see some examples of how they can be used.

The Opto 22 node packages for Node-RED video series continues with a focus on groov I/O nodes.

Get ready for another video that explains how and why to use the Node-RED programming tool on groov EPIC. In this new video, Terry Orchard explains the different types of groov I/O nodes, gives some examples of how to use them, and explains what makes them different from other nodes.

Before watching, you might want to review the Node-RED Package Intro and Configuration video. This  will provide some background on how the nodes were initially set up that are now being used in this latest I/O video.

Now, Terry has a flow ready to go with some examples that make it easy to follow along. Watch and learn.

Learn how to use Node-RED with the PAC Control node; watch the next video in our new series.

Have you been watching Terry Orchard's latest Node-RED video series that explains why you should run Node-RED on Opto 22 groov products? Last week's OptoBlog post shared how to get started with configuring the Node-RED packages so they're ready to use.

This week we move on to more details about the PAC Control node package. Watch as Terry explains in this latest video: Opto 22 Node-RED Packages: PAC Control.

Next video in our new Node-RED series: how to install and configure Opto 22 Node-RED packages.

Did you catch last week's video that made the case for why you should run Node-RED on groov EPIC and RIO? If you missed it, watch that first video to hear Opto 22's Terry Orchard explain why the groov platform is ideal for Node-RED and your IIoT and automation projects.

Next up in the series is Opto 22 Node-RED Packages: Introduction and Configuration. You'll learn how to install these packages and how to configure them so they're ready to use.
