The latest groov RIO 3.5 firmware update offers a CODESYS programming option along with enhancements for performance and security.

groov RIO firmware 3.5 is here! And the big news is the CODESYS runtime engine has been added. That means now you can run a control program on groov RIO—one you build in CODESYS using any of the IEC 61131-3 compliant languages.

The engineers have kept their fingers on the keyboard here at Opto HQ and are beyond excited about the release of version 3.5 firmware for the groov RIO family. We can't wait to see what applications our awesome customers come up with, now that the CODESYS runtime engine has been added to the complete groov RIO Trio.

Get Sparkplug 3.0 compliance, updated Node-RED, and new options for your groov EPIC controller.

The engineers at Opto 22 have been busy working around chip shortages and supply chain delays, yet even with those additional efforts, we're announcing the release of a new groov EPIC firmware update, version 3.5.

If I had to sum things up, I’d say a lot of really nice quality-of-life improvements and solid bug fixes were the key takeaways here.

Let's take a high-level look at some of the new features in this release.

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.

Version 3.0.0 of the Opto 22 Library Package for the CODESYS Development System is now available.

For all of you taking advantage of the CODESYS programming environment available for groov EPIC, you'll want to hear about this week's version 3.0.0 release of the Opto 22 CODESYS library package. With CODESYS, you can program groov EPIC for industrial control and monitoring using any familiar IEC 61131-3 compliant language.

Version 3.0.0 brings you a new collection of OptoMMP client function blocks you can use to access any area of an Opto 22 device's memory map.

A quick fix update was just released for groov RIO, version 3.4.1.

As an OptoBlog subscriber, you're always the first to hear about product news or firmware updates. This time we have another recent release for groov RIO to tell you about.

Review some important bug fixes included in the latest groov EPIC firmware update 3.4.3.

Everyone here at Opto 22 knows that updating any controller's firmware is not a trivial task, and when in a production environment, it’s not something that can be done at the drop of a hat.

That said, sometimes we fix some bugs that require a minor point firmware update and the latest 3.4.3 release is just such a case. If you are using groov View or the new Data Services feature, then you should look closely at this release as you determine where updating your controller(s) should be prioritized in your jam-packed schedule.

Following the recent groov EPIC 3.4 firmware update, groov RIO offers similar updates in its 3.4 release.

Here are some exciting additions in the latest groov RIO 3.4 package. All these new features are available in all groov RIO models: MM1, MM2 and RIO EMU.

The biggest news is the embedded OPC UA server. This is a first of its kind: a fully functioning OPC UA server option for a remote, Ethernet-based input/output module.

With every groov firmware update we also include updates to the software our devices run, whether that’s groov View, Ignition, or Node-RED. The recent groov EPIC 3.4.0 update is no different! In this post, I’ll briefly go over some of the biggest updates to Node-RED, which has been bumped to v2.2.2. If you want to know more about the 3.4.0 groov EPIC firmware, check out Ben’s forum post.

Major release adds embedded OPC UA server, expanded MQTT/Sparkplug options, SNMP, Scratch Pad data access, and more

Everyone here at Opto is very excited to announce that the latest EPIC firmware update is now live.

Just as you update the OS on your phone to get the latest improvements in security, stability and performance, the OS on your groov EPIC is no different. It is after all, a quad core Linux computer, so updates are very important for the exact same reasons: security, stability, and performance.

And often these updates come with some cool new features. With this release, you'll find several.
