OptoForums - restructured and ready to help

Posted by Janice Colmer on Dec 12, 2022 8:00:00 AM

New categories and reorganization of topics are just some of the reasons to visit the OptoForums.

Whether you're new to using Opto 22 products or a long-time user, you can benefit from checking out the OptoForums. It's where engineering minds meet to post questions, answer fellow forum user questions, recommend solutions or even provide code samples—all related to Opto 22 hardware and software.

Moderated by Opto 22's Ben Orchard and Terry Orchard, the Forums are another great resource to keep bookmarked for troubleshooting or application advice.

And the Forums recently went through some reorganization, with more topics and categories added to help you find your answers more quickly and efficiently. Take a look at what's new.

New CODESYS resources for developers

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

A new section just added to the Opto 22 Developer site supports the latest 3.0.0 release of the Opto 22 CODESYS library package.

If you haven't visited developer.opto22.com in awhile, you'll want to spend some time reviewing our latest technical guides and resources. The site gets a lot of traffic from developers working with groov EPIC, SNAP PACs, Node-RED, and even industrial I/O for Raspberry Pi. 

Since all Opto 22 products are designed on open standards, you have a variety of ways to interact with them and integrate with other systems. The developer site helps you do that.

Now we've added a section dedicated to helping you program CODESYS on groov EPIC controllers.

Connecting PLCs to the Internet...securely

Posted by Janice Colmer on Nov 2, 2022 9:00:00 AM

Watch the recording of episode 8 of IntegrateLive! - as Opto 22 and Phoenix Contact connect their PLCs to web APIs to leverage data.

If you're not familiar with IntegrateLive! yet, we encourage you to check out this new online community. Jeff Knepper and Allen Ray created this platform to help all end users, manufacturers, and system integrators in the industrial automation space.

The importance of open source technologies working together is the foundation of IL and it celebrates "Co-op-etition"—which is what brought Opto 22 and Phoenix Contact together in this latest episode.

Connecting PLCs to the Internet to Drive Sustainability

Posted by Janice Colmer on Oct 12, 2022 12:05:31 PM

Join us for another episode of an IntegrateLive! virtual workshop showcasing Linux-based PLCs.

Have you attended any virtual workshops hosted by the IntegrateLive! community? The IL platform started earlier this year as a collaboration that aligns integrators, vendors, and end users. Each episode brings together "changemakers in automation" who show how open source technologies work well together.

The result? An integrated solution ecosystem that you can use to solve everyday industrial problems.

Opto 22 is once again participating in this month's live demo to show the capabilities of edge controllers like groov EPIC. We'll be joined by Phoenix Contact in this 8th episode of IntegrateLive, happening October 26th at 8:00 am PDT (11:00 am EDT). Register to attend.

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.
