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.

Adventures of an Applications Engineer - Part 1

Posted by Mary St. John on Aug 4, 2017 1:31:13 PM

As an applications engineer, sometimes known as OptoMary on our OptoForums, perhaps I shouldn’t have favorite customers. They’re all my favorites!

Sure, our products and people have helped build flashy Vegas shows, huge amusement parks, and various NASA endeavors that we may or may not be allowed to discuss in detail. We also have the less flashy water/wastewater installations and beloved "dam customers" that can be pretty Coulee, too.

In these Adventures of an Applications Engineer posts I'll share some of my favorite favorites.

OptoNews Tip: PID loop with a long dead loop time

Posted by Jean Femia on Sep 28, 2016 4:24:57 PM

OptoForum member tohox recently posted a question about using PID control loops on a SNAP-PAC-R1 rack-mounted controller.

The issue? A really long dead loop time. 

"The time delta between the moment the strategy opens a given loop's valve [and] starts the pump+furnace and the moment a temperature increase is measured can sometimes be on the order of an hour," tohox notes.

OptoNews: Case study: M-Bus building systems data

Posted by Jean Femia on Nov 18, 2015 5:26:07 PM

How do you get a variety of building systems and machinery to communicate with a central system controller, when they use different protocols? 

Swedish system integrator Processcomponent AB had to solve this problem when they installed an energy monitoring system in a large apartment building in Gothenburg.
