### What's under the Info & Help button? Part 11 of the 12-part *groov* Manage series delves into the details.

When it comes to menu options, are you allowed to have favorites?

There is just so much cool stuff behind the "Info & Help" button for all things automation—I'm just going to start at the top and bullet point my way down the nine buttons. I could easily blog about each of the nine because of the power of each.

But you'll get a condensed summary in [*groov* Manage: Info & Help](https://www.opto22.com/support/resources-tools/videos/playlist-what-is-groov-epic?wchannelid=61lkudfc8c&wmediaid=yvt0cuupeo).

### The latest 3.5 firmware updates for *groov* EPIC and RIO include new Sparkplug 3 compatible certification.

*groov* products have always supported the MQTT and Sparkplug communication protocols, so what's important about this latest Sparkplug update?

*groov* EPIC and RIO are some of the few hardware devices to pass a series of tests for the Sparkplug Compatibility Program, managed by the Eclipse Foundation.

### 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](https://www.opto22.com/support/resources-tools/videos/playlist-what-is-groov-epic?wchannelid=61lkudfc8c&wmediaid=lhe2kbk7nz) to see why Node-RED is so popular with *groov* EPIC and RIO customers.

### 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](https://www.opto22.com/products/groov-rio/groov-rio-models).

### Take a look at using built-in Ignition software with *groov* EPIC in week 9 of the *groov* Manage series.

Here's a quick look at how you can run Ignition or Ignition Edge on the *groov* platform, using the *groov* Manage menu option.

Opto 22 has partnered with [Inductive Automation](https://www.opto22.com/community/technology-partners/tech-partner-inductive-automation) for over 6 years now, and groov EPIC was the first hardware platform to onboard the Ignition Edge program. This natural partnership has been a real success story for both sets of customers the world over.

See what's behind the [Ignition button](https://www.opto22.com/support/resources-tools/videos/playlist-what-is-groov-epic?wchannelid=61lkudfc8c&wmediaid=uuvt3mezyq) on the *groov* Manage menu.

### An easy-to-use tool for building a flexible HMI, included with your *groov* EPIC.

I don’t think I am going too far out on a limb by saying that the web browser is one of **the most** commonly installed and used software applications on any device. You might read this intro in your email app, but you will soon switch to a browser to read this blog. (I hope!)

So why stop at just viewing your SCADA HMI screens in a browser—why not build them there as well?

Enter the [*groov* View menu option](https://www.opto22.com/support/resources-tools/videos/playlist-what-is-groov-epic?wchannelid=61lkudfc8c&wmediaid=3xoua5bnmd), the focus of this part 8 of our 12-part blog series on the *groov* Manage menu.

### Move data where you need it with the Data Services menu, the latest in our 12-part video series on *groov* Manage.

Opto 22 was an early adopter of MQTT—implementing it right out of the gate when *groov* EPIC was released just over 5 years ago. And did you know that back in the day, Opto 22 was not only one of the founding members of OPC, but also that version 1.0 of the OPC specification was ratified around the granite table in the Opto 22 headquarters' conference room? 

With this history in mind, you'll see why we're excited to talk about the Data Service options you'll find in *groov* Manage. This is where you choose the methods and protocols to move your data where you need it. Follow along with [*groov* Manage: Data Services](https://www.opto22.com/support/resources-tools/videos/playlist-what-is-groov-epic?wchannelid=61lkudfc8c&wmediaid=9e6p56l90i).

### New factory saves initial and recurring costs, improves products with *groov* EPIC and Ignition.

Moving to Industry 4.0 takes time and determination, especially for an established company in a heavy industry. Castings Foundry POK in Guadalajara, Mexico, a Nucor subsidiary, uses equipment from manufacturers all over the world, which may include PLCs from a variety of automation suppliers. But data from all this equipment needed to be shared with corporate SCADA and ERP systems.  

In this new [Opto 22 case study](https://www.opto22.com/products/groov-case-studies/case-study-nucor-subsidiary-pok-brings-foundry-to), see how POK's new factory solved this problem, saving an estimated 60% in initial costs, making operators' jobs easier with comprehensive HMIs, and improving product quality.
