groov RIO Ignition Exchange Project Spotlight

See how to quickly read groov RIO data into the Ignition Exchange tag database

With software-configurable I/O, like that on the groov RIO MM1 and MM2, it’s easier than ever to instrument all your devices for control and reading back real-world data. To help you take the next step of getting that data somewhere meaningful, this post will summarize a new Ignition Exchange project for reading data from one or more groov RIO modules into your Ignition tag database.

Posted by MartinCSI, an IoT-certified OptoPartner, this project makes it trivial to dynamically get tag data into the Ignition tag database, display it on Vision pages, and link it to other projects and providers where you can then do whatever you need.

New video just added to the Node-RED developer playlist covers a simple API flow using daily weather data as an example.

Node-RED is an extremely powerful tool that we’ve featured many times on this blog and our YouTube channel, and one very common use of Node-RED is to use application programming interfaces or “APIs” to move data between devices and/or services that would otherwise be totally disconnected.

To help you get started using APIs with Node-RED if you’re unfamiliar with these tools, we’ve just made a new video about how to build a simple API flow using an example web service for daily weather data.
