OptoMMP Tools in groov Manage

Posted by Terry Orchard on Oct 5, 2023 9:20:36 AM

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.

groov Manage: Node-RED

Posted by Ben Orchard on Aug 29, 2023 1:07:09 PM

Find out what's behind the Node-RED button on the groov Manage home screen.

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.

Using security certificates with Opto 22 Node-RED packages

Posted by Janice Colmer on May 17, 2023 10:22:24 AM

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.

RTD with RIO

Posted by Terry Orchard on May 4, 2023 2:30:00 PM

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.
