[Tweet](https://twitter.com/share) ### 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. [IIoT](https://www.opto22.com/support/resources-tools/demos/groov-epic-groov-rio-architecture)[System Architecture](https://www.opto22.com/support/resources-tools/demos/groov-epic-groov-rio-architecture)[![](https://www.opto22.com/Opto22/media/demos/groov_epic_rio_arch_th.jpg?ext=.jpg)](https://www.opto22.com/support/resources-tools/demos/groov-epic-groov-rio-architecture) [Click through each of the steps](https://www.opto22.com/support/resources-tools/demos/groov-epic-groov-rio-architecture) in this online demo to see how [groov EPIC](https://www.opto22.com/products/groov-epic-system) and [groov RIO's](https://www.opto22.com/products/groov-rio) security and connectivity options interact to build bulletproof infrastructure. Each step adds illustrations and descriptive text to guide you through the build.  The result is a complete system overview of a multi-vendor network and software integration. It illustrates how to: - Secure legacy PLCs and acquire their data without disturbing existing systems - Remotely access field devices through secure, on-demand VPN conduits - Securely share data with SCADA systems and MQTT applications - Scale out your infrastructure using *groov* RIO edge I/O    --- [groov View Primer](https://www.opto22.com/support/resources-tools/demos/groov-view-primer)[![](https://www.opto22.com/Opto22/media/demos/groovviewprimer.jpg?ext=.jpg)](https://www.opto22.com/support/resources-tools/demos/groov-view-primer) With browser-based *groov *View, you can easily build a web-based, responsive operator interface to see and interact with exactly what you need. *groov *View is included with *groov* EPIC and also available separately for Windows-based PCs [(*groov*](https://www.opto22.com/products/groov-svr-win-base)[ Server for Windows).](https://www.opto22.com/products/groov-svr-win-base) To take a deeper dive into what you can do with it, check out the groov View Primer. The [demo](https://www.opto22.com/support/resources-tools/demos/groov-view-primer) shows: - User interface examples - Built-in gadget library available for your designs - Custom graphic options - Animated indicator gadget options   --- [Accuracy vs Resolution](https://www.opto22.com/support/resources-tools/demos/accuracy-vs-resolution)[![](https://www.opto22.com/Opto22/media/demos/accres_th.png?ext=.png)](https://www.opto22.com/support/resources-tools/demos/accuracy-vs-resolution) Some applications require highly accurate values or very fine resolution, while others do not. Choosing the right I/O module for your application will save you time and money. So here's a [hands-on demo](https://www.opto22.com/support/resources-tools/demos/accuracy-vs-resolution) for you to really see how accuracy and resolution work. You can review the definitions, see what happens when an analog value is morphed into a digital value for computers to use, and check out the example of a temperature probe.    --- [Sinking vs Sourcing](https://www.opto22.com/support/resources-tools/demos/sinking-vs-sourcing)[![](https://www.opto22.com/Opto22/media/demos/sinksource_th.png?ext=.png)](https://www.opto22.com/support/resources-tools/demos/sinking-vs-sourcing) In automation, we often do not have a choice. We have to choose sinking or sourcing because of the way transistors are made, the way electrical panels are wired, or the availability of the electrical/electronic parts we are given to use. This [animation](https://www.opto22.com/support/resources-tools/demos/sinking-vs-sourcing) demonstrates sinking and sourcing, and the digital output modules to use with each.      ---   [![TimeStamptoExcel](https://blog.opto22.com/hs-fs/hubfs/TimeStamptoExcel.png?width=300&height=99&name=TimeStamptoExcel.png)](https://www.opto22.com/support/resources-tools/demos/convert-date-stamps-(groov-to-excel))[Convert Date Stamps to Excel](https://www.opto22.com/support/resources-tools/demos/convert-date-stamps-(groov-to-excel))  See how to copy and paste data from an exported *groov* View trend into a field, and convert the time stamps to a common time format used in Excel.       --- [PID Tuning](https://www.opto22.com/support/resources-tools/demos/pid-reaction-curve-tuning-for-interactive-pid-alg)[![pid_tuner_320x161-2](https://blog.opto22.com/hs-fs/hubfs/social-suggested-images/pid_tuner_320x161-2.png?width=300&height=151&name=pid_tuner_320x161-2.png)](https://www.opto22.com/support/resources-tools/demos/pid-reaction-curve-tuning-for-interactive-pid-alg) In automation, proportional integral derivative (PID) control loops are common, useful, and tricky to get right.  Each loop is different and each requires individual tuning for maximum effectiveness. This [demonstration](https://www.opto22.com/support/resources-tools/demos/pid-reaction-curve-tuning-for-interactive-pid-alg) guides you in applying the Ziegler-Nichols Reaction Curve, or Open-Loop tuning, method of estimating PID tuning parameters. Plug in data for your PID and the tuner calculates P, I, and D values for tuning, plus a suggested scan rate.   These are just a few of the demos to choose from. Don't stop there. Check out our [complete list](https://www.opto22.com/support/resources-tools?rt=77&page=1) of interactive demos, and we hope you continue on your learning path!   Topics: [PID loop control](https://blog.opto22.com/optoblog/topic/pid-loop-control), [groov View](https://blog.opto22.com/optoblog/topic/groov-view), [groov EPIC](https://blog.opto22.com/optoblog/topic/groov-epic), [groov RIO](https://blog.opto22.com/optoblog/topic/groov-rio), [IIoT System Architecture](https://blog.opto22.com/optoblog/topic/iiot-system-architecture), [interactive demo](https://blog.opto22.com/optoblog/topic/interactive-demo) ### Written by [Janice Colmer](https://blog.opto22.com/optoblog/author/janice-colmer) Janice has worked at Opto 22 for over 20 years and is part of the marketing team that strives to share new and relevant content with the industrial automation industry.
