Category: Alarm Notification

Open Automation Software can send alarm messages via SMS or Email from multiple Industry 4.0 data sources. Sparkplug B is one of the possible data interfaces as a Host Application or Edge of Network Node. This tutorial walks you through downloading and installing OAS, configuring a Sparkplug B driver, automating tag creation, configuring alarm limits, and configuring alarm notifications. Based on specific filter criteria, alarm notifications can be sent to users via email, SMS text, or voice.

Step 1. Download and Install the Open Automation Software and Start the OAS Service

If you have not already done so, you will need to download and install the OAS platform.  Fully functional trial versions of the software are available for Windows, Windows IoT Core, Linux, Raspberry Pi and Docker on our downloads page.

On Windows run the downloaded Setup.exe file to install one or more of the Open Automation Software features. Select the default Typical installation if you are not sure what features to use or the Custom installation if you want to save disk space on the target system.  When prompted agree to the End User License Agreement to continue the installation.

For more detailed instructions and video tutorials, visit the installation guide for your system:
Windows Installation | Linux Installation | Raspberry Pi Installation | Dockers Installation

When the installation is finished the OAS Service Control application will appear.  Use this application to start the 4 Services. If this is the first time installing the software it will automatically enter Runtime with an example Tag Configuration.

Step 2. Set Up Sparkplug B Host App to Access EoN Node Data.

Select Configure-Drivers.

Enter a meaningful Driver Interface Name that you will refer to this connection and define the properties.

Set the driver to Sparkplug B.

Enter the Host property to the IP Address of the of the host broker or just use localhost for a local broker. 

Set the Port property of the host broker to connect to.  The default port is 1883 or 8883 for SSL.

Note: The OAS MQTT Broker can be used to host data locally.  To use another broker on the default ports on the same computer change the OAS MQTT Broker Port under Configure-Options-MQTT Broker.

Enter the User Name and Password if required.

Set the MQTT Protocol Version to V311 or V500.

Set the Client ID to a unique value, each driver interface must have a specific value different than all other clients connecting to the host.

Set the Mode to Host App for OAS to control the online state of each Edge of Node defined to the shared Host Application ID. Or set to Client App to access EoN Node data without controlling their state.

Set the Host ID to the specific value that the Edge of Nodes will be using as the Host Application ID.

Set the Sparkplug B Version to 2.2 or 3.0.

To automatically add tags for each Metric from the matching Group, Edge of Nodes, and Devices enable the property Add Client Tags Automatically.

When enabled optionally set the Filter Groups, Edge Nodes, and Devices that tags should be added from for each of their Metrics.  Leave the Filter fields blank to include all Edge of Nodes publishing data to the broker.

Select the Add Driver button in the left part of the form to add the Driver Interface as an available selection when defining Tags in the next step.

You are now ready to add tags for specific Sparkplug B EoN Node Metric values.

Note: If the Driver Interface property Add Client Tags Automatically was enabled tags will be created for you, you can skip this step to add tags manually.

Select Configure-Tags.

Note: You can add organizational Groups as many levels deep as you prefer and add tags to groups.  To do this first add a Group to Tags Group at the root level, then right click on the Group in the right window to add additional Groups or Tags.

Select Add Tag.

Change the Data Source Tag property to Sparkplug B.

Select the correct Driver Interface from the Driver Interface pull down list.

Specify the Client Group ID, Client Edge Node ID, Client Device ID, and Client Metric Name for the Edge of Node Metric value to read and write.

Select the Data Type of the Tag to match the data type of the Metric.

Select Apply Changes and the current value for the Metric should appear with Good Quality.

Select the Save button from the toolbar to save your configuration.

Step 3. Configure Alarm Limits

1. In the OAS Configure Application, select Configure >> Tags from the top menu.
   
   


2. Select localhost or the remote service you wish to modify with the Select button to the right of the Network Node list.
   
   


3. Select the tag you wish to set alarm limits for from the tag browser on the left.


4. Use the tabs at the top of the tag properties window to configure alarm limits for your tag based on type: High High, High, Low, Low Low, Digital and Rate of Change.
   
   


5. Check the Enable Alarm checkbox to enabling your alarm limit; alternately, you can use he Enable with Tag…checkbox.
   
   


6. Set your Alarm Limit Source with the dropdown box. If you choose Value, enter the value in the provided text field.


7. When you have finished configuring your alarm limits, click Apply Changes in the bottom right of the properties window.

Step 4. Configure Alarm Notifications

1. In the OAS Configure Application, select Configure >> Alarm Notification from the top menu.
   
   


2. Select localhost or the remote service you wish to log alarms from with the Select button to the right of the Network Node list.
   
   


3. A Notifcation Group screen will appear. Give your group a meaningful name in the Notification Group Name box.


4. In the Common tab, check Notification Active to activate your group. Alternately, check Enable Notification with Tag… and choose a tag with the Browse button that appears.


5. Use the Filters tab to select which types of alarms you want in this group. Alarms can be filtered based on Alarm Priority, Alarm Groups, and Alarm Types.


6. Use the Email tab to configure alarm notification via email.
   
   
7. Use the SMS tab to configure alarm notification via text. You will need to create an account with Twilio (www.twilio.com) to handle SMS/Voice notifactions.
   
   
8. Once you have finished configuring your notification group, click the Add Group button in the left panel to add your new group.
