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.

Notice in the timeline below the video, you can jump ahead or go back to specific chapters in the presentation. Chapters include:

• Read node
• Using a filter deadband
• Input node
• Digital output control
• Memory mapped protocol addresses

We hope you've been finding this series helpful. You can contact us with your Node-RED programming questions or join the discussion on the OptoForums.

Thanks for watching!
