A recent firmware release provides important updates for groov RIO MM1 and MM2 devices.

Keep your groov RIO edge I/O module up to speed with the latest firmware updates and fixes. The recently released groov RIO firmware version 3.3.1 is now available. Here are some reasons you'll want to update.

RIO MM1 3.3 firmware update

Version 3.3.1 is for both universal I/O RIO modules: GRV-R7-MM1001-10 and GRV-R7-MM2001-10.

Fixes and improvements in this release involve:

  • WiFi configuration changes
  • Scaling values for analog channels
  • Digital output channels running with a PAC Control strategy

Please reference the groov RIO Firmware Readme for complete release details.

Note: updating firmware can sometimes take 20-30 minutes or more to complete and restart your groov RIO, so we suggest scheduling the update during a time when it minimizes impact to your automation processes and equipment.

You'll find step-by-step instructions for upgrading groov RIO firmware on page 116 of the groov RIO User's Guide.

And don't forget! 

Each RIO has its own firmware download page. Be sure to get the right one for your hardware.
RIO MM1:  GRV-R7-MM1001-10 Firmware 
RIO MM2: GRV-R7-MM2001-10 Firmware



We hope you're able to take advantage of these new updates. Contact us with any questions that come up during the update process or email our Product Support team at support@opto22.com.

Keep calm and groov on!
