Power and energy monitoring with Modbus

Darran News

Get some tips on using the groov RIO EMU with other Modbus TCP/IP devices.

The Modbus protocol has been around since the late 1970’s. This is both amazing and cool. Amazing as some reading this have been using it since then (how time flies!). Cool because it’s been around so long, and well established and widely used.

Opto 22 products have been supporting Modbus TCP since way-back-when. Out of the box, our devices are Modbus TCP slaves (now called “servers”) and can be polled for data on specific register addresses. The groov RIO EMU (Energy Monitoring Unit), one of our newest products, is no different.

Important: Update to continue sending emails from Opto 22 products

Darran News

New technical note shows you how to update security settings for your email applications.

You can use many Opto 22 products to send email notifications to keep engineers and technicians aware of important conditions in your system. For example:

  • You can send email through a PAC Control strategy running on a groov EPIC or SNAP PAC controller.
  • Your groov View HMI can send event notifications via email.
  • Your Node-RED flow on groov RIO or groov EPIC can send email.

But you must make changes now to keep receiving emails!

Programming with CODESYS and need a Modbus master?

Darran News

groov EPIC becomes a Modbus master/client with a few easy lessons.

With Modbus continuing to be a popular protocol for industrial devices, the chances are pretty good you will need to write a program to communicate with Modbus slave/server devices more than a few times. The groov EPIC controller offers several Modbus communication options, and CODESYS, an IEC 61131-3 compliant development environment, is one of them.

With your PLC programming experience and the Using groov EPIC as a Modbus Master in CODESYS course on OptoU, creating a CODESYS project with Modbus master functions will be a breeze.

Google Apps ending access to less secure apps – are you ready?

Darran News

Prepare to make security changes to your email accounts by May 30, 2022.

For a long time, automation engineers have sent email alerts and reports from automation applications via a ‘throwaway’ Gmail account. This seemed harmless enough at the time and really useful, but it wasn’t very secure. As email abuse has risen over the years, it’s time for the “less secure” party to come to an end.

Does this mean an end to all email alerts? Not at all. You just need to adjust your Google Gmail settings and update to a new application password in each application. Of course, this applies (with different end dates) to most other email providers as well as Google; check with your email provider for details. This blog will focus on Google Gmail.

Power & Energy Monitoring – Why and how?

Darran News

New website resources outline how to securely access and share your energy data.

Opto 22 gives you lots of options when it comes to helping you monitor your power and energy usage.  The groov RIO EMU (energy monitoring unit) is an edge I/O module meant for easy distributed power and energy monitoring of one 3-phase load. Check out our previous announcements for all the details.

However, for monitoring multiple loads located near each other, and for a complete system including real-time control, groov EPIC with power monitoring modules might be the better choice.

But, you might have more questions about which is the right solution for you, why and how do you get started monitoring your machine health or energy data? And how do you do it securely?

Check out our new website resources for some guidance on these important energy topics.
