Posted by Janice Colmer on Dec 8, 2022 8:00:00 AM

Learn more about automation products and IIoT technologies through the Interactive Demo section on the website.

Many people benefit from hands-on learning, which is why we've always maintained a section of interactive resources on the Opto 22 website. If you haven't tried it yourself, take a few minutes to point, click, and discover some new product features and functions.

These website demos cover advanced edge computing and IIoT concepts using groov EPIC and RIO products, building custom HMIs with groov View, and even basic automation 101 concepts like PID turning.

Here are some website demos you can explore.

More options for HMI animations

Posted by Janice Colmer on Oct 19, 2022 10:07:48 AM

New images and animations are added to our SVG image library and GIFs resource page.

Are you building HMI screens to use with your groov EPIC (GRV-EPIC-PR1 or GRV-EPIC-PR2)? Be sure to visit our website resource pages to help customize your HMI. We've expanded the SVG Image Library as well as the Animated GIFs section of the site.

These images and animations work especially well if you're using browser-based groov View. Included with your EPIC, groov View lets you easily build an operator interface to see and interact with exactly the devices and data you need. Choose from a variety of images suited for all kinds of industrial applications.

Quick recap: groov EPIC 3.4.3 firmware update

Posted by Ben Orchard on Aug 16, 2022 12:37:43 PM

Review some important bug fixes included in the latest groov EPIC firmware update 3.4.3.

Everyone here at Opto 22 knows that updating any controller's firmware is not a trivial task, and when in a production environment, it’s not something that can be done at the drop of a hat.

That said, sometimes we fix some bugs that require a minor point firmware update and the latest 3.4.3 release is just such a case. If you are using groov View or the new Data Services feature, then you should look closely at this release as you determine where updating your controller(s) should be prioritized in your jam-packed schedule.

Now Serving: PAC Control and Memory Mapped Data with OPC UA Server

Posted by Norma Rodriguez on Jul 6, 2022 7:30:00 AM

groov EPIC OPC UA Server makes it easy to access your data; lessons on OptoU show you how

Do you need access to your PAC Control strategy variables and I/O, or data from the memory map area on your groov EPIC? Do you want to connect to OPC UA client applications such as SCADA, MES, or enterprise software?

groov EPIC is now serving up this data securely and reliably with its built-in groov EPIC OPC UA Server. Publish the data where you need it.

In this post, we’ll go over exactly what data is accessible from the server, the basics of configuring the server, and some examples of how you can use it. And when you’re ready to work with the OPC UA server, you can find step-by-step instructions in the groov EPIC OPC UA courses on OptoU.

Important: Update to continue sending emails from Opto 22 products

Posted by Janice Colmer on May 18, 2022 7:00:00 AM

New technical note shows you how to update security settings for your email applications.

You can use many Opto 22 products to send email notifications to keep engineers and technicians aware of important conditions in your system. For example:

  • You can send email through a PAC Control strategy running on a groov EPIC or SNAP PAC controller.
  • Your groov View HMI can send event notifications via email.
  • Your Node-RED flow on groov RIO or groov EPIC can send email.

But you must make changes now to keep receiving emails!

Flexible, low-cost water monitoring with edge I/O

Posted by Janice Colmer on Feb 11, 2022 7:30:00 AM

Remote I/O over MQTT helps Rust Automation deploy affordable remote monitoring in a challenging environment.

Did you watch the Fall CODESYS Tech Talk virtual event that we shared with you last October? It demonstrated how the CODESYS runtime engine works and why it's included on Opto 22's groov EPIC.

Jared Bates, from OptoPartner Rust Automation & Controls, joined us for that presentation. He discussed a current water management application that utilizes CODESYS on EPIC, groov RIO remote I/O, and MQTT for secure data communications. 

Now, we've put the story of all that cutting-edge technology into a case study, so you can dig into all the details!

How to select the right HMI solution for your groov device

Posted by Josh Eastburn on Sep 2, 2021 11:00:00 AM

Sharpen your drawing tools. It's time to go to work.

Visualization for industrial automation is bigger than it’s ever been, and it’s not just about control anymore. As it becomes increasingly important to turn data into information efficiently and ubiquitously, visualization platforms deal with more data types, presentation formats, and a broader range of users and use cases. As always, Opto 22 gives you many tools so you can choose what fits your project best. Let’s take a look at some of those options.
