See what Opto users were talking about as we look back at last year's Top 5 posts on the OptoForums.

A local database server on your groov EPIC processor?

Posted by Ben Orchard on Aug 30, 2019 8:00:00 AM

In a recent blog post, Terry Orchard covered one of the programming options available on the groov EPIC: secure shell (SSH) access. If you’re familiar with Linux shell commands, you can use secure shell access to install application packages and add functionality to your groov EPIC Edge Programmable Industrial Controller.

For example, you could add a local database server.

groov EPIC 1.4 means more Ignition

Posted by Ben Orchard on Aug 26, 2019 7:35:14 AM

The groov EPIC has always come pre-installed with Ignition Edge® by Inductive Automation® on board. Ignition Edge in the EPIC means you have OPC-UA drivers built in to communicate with other control systems (for example, Allen-Bradley and Siemens PLCs). It also means you can use MQTT/Sparkplug for more efficient and secure data communications. 

But starting with groov EPIC firmware version 1.4.0 (released in August 2019), that changes—in a good way. You now have the option to choose which edition of Ignition you run on your Edge Programmable Industrial Controller—either Ignition Edge or full Ignition.

groov EPIC Security Series, Part 6: Linux Operating System and Repository

Posted by Ben Orchard on Jun 6, 2019 1:12:33 PM

The OS, or operating system, of groov EPIC is very different from traditional controllers. Instead of a proprietary OS, EPIC uses an open-source Linux® operating system.

From a security standpoint, an “open source” OS sounds scary. But in many ways it is more secure than a closed-source one, especially a well-known and often-attacked OS such as Microsoft® Windows®.

groov EPIC Security Series, Part 5: Encryption and Certificates

Posted by Ben Orchard on May 22, 2019 11:05:13 AM

Go on, admit it. At some point in your life you've written down a password on a piece of paper in clear text. Anybody walking by can simply glance at your note, and they'll know what your password is.

No, you have never done that? Excellent. 

But if you've ever used your web browser to log into a website over the web, and entered sensitive information like your password without encryption, you've effectively transmitted that information through the internet for all to see, almost like writing it on paper and showing it around.

Whoa.
