Video series gives you tips for using Modbus TCP devices with groov EPIC

Posted by Janice Colmer on Jan 7, 2020 9:09:43 AM

Watch these new groov EPIC videos for tips on using your Modbus TCP devices with groov View, PAC Control, Node-RED, and Inductive Automation's Ignition software.

Opto 22 engineer Ben Orchard is back in the Opto 22 studio with several new video lessons on communicating to Modbus TCP devices with a groov EPIC processor.

For each lesson, Ben is using a groov EPIC Learning Center (GRV-EPIC-LC) along with a Modbus SATEC P130 power meter, which is measuring the voltage and frequency of the mains power in our studio.

Outside-In Journal: Training Day Part 1

Posted by Josh Eastburn on Sep 4, 2019 10:18:01 AM

Documenting the journey from the outside world into the world of Opto: First in a series.

After more than a decade as an automation engineer, I recently joined Opto 22’s marketing group. A few weeks ago, my workday was focused on maintaining the cell culture process automation of a world-class pharmaceutical manufacturer. This system had dozens of distributed controllers and hundreds of devices that worked together to deliver thousands of kilograms of the finest monoclonal antibodies you’ve ever seen. It was big.

What I enjoyed most about my job, though, was helping other engineers succeed. In the early years, I learned pretty quickly that you could take a group of smart people, give them bad tools, callous management, and a ridiculous schedule, and they would fail every time. I did the best I could to fix the managerial and scheduling issues, but the tools were always a limitation.

Now it’s my job to help connect other engineers with the kinds of tools and technologies I wish I’d had. I’m kicking it off with a deep-dive into the first place I visited as a new Opto employee: the training room.

If you’re wondering whether it’s worth your time and money to get some Opto training yourself, I’ll be walking through everything you can expect to experience.

Start EPIC communication to your serial devices

Posted by Janice Colmer on Jul 30, 2019 10:56:51 AM

Learn how to set up, install, and communicate using a groov EPIC serial I/O module.

Many industrial automation applications require communication between the controller and multiple serial devices. The GRV-CSERI-4 module provides four independent and isolated serial ports for this purpose. Each port is software configurable to communicate with RS-232 or RS-485 (half duplex or full duplex) serial devices.

I/O module quality indicator LED sheds light on system status

Posted by Janice Colmer on Jul 22, 2019 10:21:08 AM

New video workshop takes a closer look at the LED quality indicator on groov EPIC I/O modules.

Are you seeing a yellow light on one of your groov EPIC I/O modules? This means that one or more of its values is outside of the expected range. Opto 22 applications engineer Ben Orchard explains why this is important and how to use this feature in a video that's just been added to the groov EPIC hardware playlist.
