Your data where you need it.

The industrial internet of things is all about connectivity.

groov products use both OT (operation technology) and IT (information technology) protocols, so you can easily and securely connect and communicate data with all of these:

  • On-premises software, online services, and other APIs (application program interfaces)
  • Inductive Automation® software
  • MQTT brokers
  • OPC UA clients
  • Allen-Bradley® and Siemens® S7 PLCs
  • Modbus®/TCP devices
  • Opto 22 groov EPIC® systems and groov RIO® modules
  • Opto 22 SNAP PAC controllers and I/O units
  • Any Node-RED node

“The fluidity and dynamics of modern manufacturing requires extremely fast response to changing market demands... With groov EPIC and groov RIO, Opto 22 puts dynamic manufacturing data at the edge of the production line and into enterprise systems simultaneously in real-time.”

 – Tom Coombs, principal engineer, Northeast Automation Controls (System Integrator)

I/O at the edge for reliable data

Connect groov RIO edge I/O modules and groov EPIC I/O directly to field devices and sensors. Field data is your single source of truth—the real data needed to make business decisions.

Then easily process, store, and communicate this vital data acquired through edge I/O. Use built-in software like Node-RED and efficient protocols like MQTT to communicate field data anywhere you need it. 

In the age of the IoT, groov products let you gather, use, and view the data you need, when and where you need it.

Connect to legacy PLCs and systems

Allen-Bradley, Siemens, Modbus, and more: connect to in-place automation systems and equipment and acquire data without disturbing existing processes.

  • Connect groov RIO or groov EPIC I/O to proprietary machines to parallel machine I/O, gaining data without affecting existing processes.
  • Securely connect devices, systems, and software using automation standards like OPC UA.
  • Move data from legacy equipment to databases and analytical software on premises or in the cloud.
  • Mix equipment and data from different sources in the same groov View operator interface.
