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!

Google Apps ending access to less secure apps - are you ready?

Posted by Ben Orchard on May 9, 2022 10:08:18 AM

Prepare to make security changes to your email accounts by May 30, 2022.

For a long time, automation engineers have sent email alerts and reports from automation applications via a ‘throwaway’ Gmail account. This seemed harmless enough at the time and really useful, but it wasn’t very secure. As email abuse has risen over the years, it's time for the “less secure” party to come to an end.

Does this mean an end to all email alerts? Not at all. You just need to adjust your Google Gmail settings and update to a new application password in each application. Of course, this applies (with different end dates) to most other email providers as well as Google; check with your email provider for details. This blog will focus on Google Gmail.

Case Study: Using Edge I/O to Automate Quality Control

Posted by Josh Eastburn on Mar 9, 2022 9:08:32 AM

Intrinsics Imaging’s AI-powered vision system uses groov RIO to connect the cloud to the edge.

Machine vision systems can recognize superficial aberrations in manufactured goods—like lines, spots, holes, color discrepancies, and more—that would typically require time-consuming manual inspection. California-based Intrinsics Imaging solves this problem with its Heijunka Vision analytics-as-a-service software. But when Intrinsics was approached by a customer hoping to integrate Heijunka directly into process controls, it looked to Opto 22’s groov RIO edge I/O for a way to connect the cloud to the edge.
