A step by step Corso Systems tutorial for configuring OpenVPN on Opto 22’s groov EPIC groov RIO devices. This detailed guide includes working code samples and more.

Corso Systems can convert your legacy Allen Bradley PLC code to run on USA-made and readily available, modern Opto 22 hardware like the groov EPIC and groov RIO. Upgrade quickly with our conversion tool.

Building on our a previous post integrating database records into a table in Opto 22's groov View HMI platform, Corso Systems walks through adding a search capability to the screen. Operators can now search a database in real-time with Node-RED handling the backend operations to query and return the data.

Corso Systems is building out a database integration for use in a groov View system. Operators need to view data stored in a database, retrieve it in a paged fashion and to move between the various pages of records in the HMI. Our tutorial shows how this can be done using groov View along with MySQL and Node-RED.

Corso Systems continues a tutorial developing a recipe management system in Opto 22's groov View platform. Node-RED is used to send/receive data from groov View and interact with a database. This post covers setting up groov View and Node-RED so you can use groov View to enter and read recipe data into/from a database.

Corso Systems shares a step by step tutorial for setting up Node-RED to communicate with a database. Including building a Node-RED dashboard to add user input. We also discuss the overall workflow for integrating with an Opto22 groov View and a groov EPIC PLC.

Corso Systems sets up a dashboard HMI screen using the groov View HMI package included free with every Opto22 groov EPIC PLC. Our brief tutorial covers configuring tags, value displays, tag history, and trends using the groov View platform.

Corso Systems built a fun and unique map-based SCADA project with groov Epic controllers from Opto22, MQTT Modules from Cirrus Link, and Inductive Automation's Ignition Perspective. Two of our engineers tracked their cross-country Amtrak journey including pictures and video.

Corso Systems walks through the process of connecting an Opto22 groov RIO to a HiveMQ MQTT Broker in the cloud, then syncs the HiveMQ MQTT Broker to an Ignition Gateway running in the cloud. Once connected data flow is validated with tags created automatically in the Ignition gateway using Sparkplug B.

Tailscale is a powerful tool in the networking arsenal. This post goes through a handful of use cases Corso Systems has used to solve problems other technology couldn’t solve.

Corso Systems walks through setting up Tailscale on an Opto22 groov RIO. Tailscale is built on the Wireguard framework, but can be easier to configure depending on your IT skillset.

Learn how Corso Systems configures a groov RIO as the heart of a low I/O count control system we have reached a new level of functionality by using the RIO as a VPN tunnel into the controls network.
