PLCnext Email & Text Alerts

Print

Once you have your Phoenix Contact PLCnext Control data flowing to the cloud, it's time to setup alerts and notifications so that you can easily monitor everything. I prefer using Microsoft Logic Apps for sending email and text alerts when temperatures rise above a specified threshold. But first things first, let's get our PLCnext Control connected to Microsoft Azure.

Phoenix Contact has a video at https://youtu.be/QST1RpTkdfA that shows how to connect your PLCnext controller to an Azure IoT Hub using a Node.js client. It's a great video and very informative. However, instead of going through all of the tedious steps outlined in the video of setting up an Azure resource group, the IoT Hub, storage containers, the storage endpoints, and everything else, I prefer to use Fathym's IoT Ensemble. With one click I can register my PLCnext device and immediately get access to the data for downstream use in alerts, dashboards, and visualizations. After I enroll my device in IoT Ensemble, it displays the IoT Hub connectionstring. I take the connectionstring into PLCnext Engineer to use as my Azure Key and I'm ready to rock. Here's a screenshot of my connected PLCnext Control.

The PLCnext data is immediately flowing to IoT Ensemble and I can view the data on screen. Reminder that behind the scenes in IoT Ensemble the PLCnext data is stored in Microsoft Azure in blob storage, as well as in CosmosDB.

How to access data in Microsoft Azure:

Fathym's IoT Ensemble is providing an easy-to-use UI for interacting with the data instead of using the Azure portal - and it saves me a ton of time and money.

PLCnext Email & Text Alerts in Logic Apps

Now that my PLCnext data is flowing to IoT Ensemble, it's time to setup the email alerts using Logic Apps. This IoT Ensemble doc explains how to use Logic Apps to call the IoT Ensemble warm query every 12 hours and check if the Temperature of any of the results is greater than 45. If so, it sends an email alert. Here's a screenshot.
