The 4.1 groov firmware release is now available and offers more control, greater security, and fewer barriers.

If you use, or plan to use, groov hardware, this update improves what you can do without adding hardware, software licenses, or external tools.

And it’s available for every groov EPIC and groov RIO device ever shipped!

Firmware 4.1.0 adds key features: network segmentation on groov RIO, serial integration inside CODESYS without licensing, and API-driven fleet management tools.

Here is what changed, and why each change is worth your attention. 

Guest blogger Michaela Pauly of OptoPartner Perceptive Controls outlines why they use groov products in their projects and how it has created more engineering job opportunities.

Are you currently seeking engineering positions in industrial automation? Do you want more opportunities to solve customer challenges with the right programming tools and solutions for the job?

You could be the perfect fit for OptoPartner Perceptive Controls. They are currently recruiting engineers interested in putting their talents to the test.

Find added security, expanded communication options, and upgrade details in this migration tech note.

Are you holding off on upgrading your control system because you’re dreading the potential downtime? Do you think you’ll have to rip and replace your existing field wiring and I/O cabinets? Are you wondering how much of your working PAC Control logic has to be rewritten?

These are valid concerns and reasons to hesitate when touching a system that’s currently keeping your plant running. However, migrating to groov EPIC (Edge Programmable Industrial Controller) is designed to be much smoother and more flexible than a typical system overhaul.

Opto 22's Migrating from SNAP PAC to groov EPIC technical note provides the details about navigating this transition. And here are some major advantages you’ll gain by upgrading to an EPIC system.

Learn how you can measure and securely manage power and energy usage data across your facility.

Are you working on machine health initiatives and predictive maintenance? Do you want to track (and reduce) operating costs?

groov products offer a simple, flexible, industrial way to monitor power and energy where it's used and securely send that data where it's needed for analysis and decision-making.  

Here's your chance to learn more about the groov RIO energy monitoring unit (GRV-R7-I1VAPM-3), or RIO EMU for short.  It  brings connectivity to projects that require power and energy data acquisition and communication. Whether you're already using groov RIO for energy monitoring or still researching your options, the groov RIO EMU User's Guide can help you understand its full capabilities and features.
