Production Specification

*** NOTE: This product is obsolete. The groov Box appliance (GROOV-AR1-BASE) and groov Server for Windows (GROOV-SVR-WIN-BASE) now include the equivalent of a Plus license. You do not need to buy this license. ***
GROOV-LIC-PLUS provides the groov Plus license when purchased in addition to either the groov Box appliance (GROOV-AR1-BASE) or groov Server for Windows (GROOV-SVR-WIN-BASE).

groov Plus lets you monitor and control as many of the following as you need:

  • Modbus/TCP devices
  • Opto 22 SNAP PAC controllers (SNAP PAC R-series, S-series, SoftPAC)
  • Opto 22 SNAP PAC I/O units (with EB-series brains or R-series rack-mounted controllers)
  • groov Data Stores (databases, cloud services, and other software APIs can write data to or read data from a Data Store)
  • OptoEMU Sensor energy monitoring units

groov Plus links you to a wide variety of sensors, equipment, and data. No intermediary servers or protocol converters are required.

For more information on groov,  see groov System.

NOTE: To monitor and control OPC UA-compatible devices and equipment in addition to multiple Modbus/TCP devices, Data Stores, and SNAP PAC controllers and i/O units, purchase GROOV-LIC-ENT.

groov Maintenance Technical Note

What is groov maintenance, what happens when it expires, and how do you renew it? This technical note answers all your questions about groov maintenance.

Opto 22 Mobile Apps for Automation

Opto 22 offers two types of mobile apps for use in automation:

- Diagnostic and commissioning apps for Opto 22 SNAP I/O and SNAP PAC Systems: Opto iPAC and Opto aPAC.

- Monitoring and controlling apps for almost any automation system or equipment from any manufacturer, including Opto 22 SNAP PAC Systems: groov View for iOS and groov View for Android.

This technical note compares these two types of apps and describes the best ways to use each.

Getting Started with the groov Free Trial

This document walks you step-by-step from getting your free trial of groov to viewing a simple mobile operator interface that you've built yourself using groov.

The document also explains how to download and install the groov demo project, a fully-functional operator interface that demonstrates many groov features and gadgets.

Using Commercial Off-the-Shelf Mobile Devices in Industrial Automation

"Russian Roulette" or the "New Normal"?

Automation engineers heatedly debate the pros and cons of using standard COTS smartphones and tablets in industrial settings. Meanwhile, industry analysts like Gartner and ARC Advisory Group forecast tremendous growth in BYOD (bring your own device) usage.

Are there reasons to use off-the-shelf mobile devices in industrial automation? What are the advantages and disadvantages, and what do you need to think about before moving ahead? This white paper discusses environmental, safety, security, connectivity, and other factors to consider and includes specific advice for choosing device types suited to your industrial application.

Setting Up groov Mobile Apps Technical Note

Opto 22's free groov View apps for iOS and Android allow you to use View for one or more groovs on your smartphone or tablet in full-screen mode without the address bar, toolbars, and other things you see in a browser. To get a groov View app for your mobile device, go to your app store and search for “groov View.”

This technical note describes how to set up the groov App on your mobile device.

Building an HMI that Works: New Best Practices for Operator Interface Design

Human Machine Interfaces (HMIs) are requiring a new standard in today’s automation industry. This white paper takes a look at the industry's new best practices for building an effective HMI. You'll find out what's wrong with most HMIs and why, see some of the research behind those that work, and learn specific ways to make yours better.

Whether you're starting an HMI from scratch or thinking about adding to or changing yours, the information in this paper will help you build an HMI that increases productivity, saves downtime, and avoids accidents.

groov Demo

A fully-configured groov project demonstrating how to build and use both simple and complex gadgets.

In the demo you’ll see how to:
• Show the value from a temperature sensor in the submersible James Cameron used to explore the bottom of the Marianas Trench
• Control a tank level and an auger in a brewery
• Trend electrical demand data for a wind farm

We’ll also look at some more complex capabilities, like these:
• Show a rotating graphic in your interface, like a compass
• Show machinery states with animated GIFs, like the turbines at the wind farm
• Indicate changes with multiple images, like the fermenter’s tank level in the brewery
