Introduction
With the latest release 2510 of SAP Asset Performance Management (APM), major features in the context of device connectivity and management were enabled and are available as part of the Early Adopter Care (EAC) program. These features utilize the embedded IoT capabilities powered by Cumulocity.
Only two months after its introduction in version 2506 (see also this blog article describing the initial release), many IoT centric features such as direct integration support for OT (operations technology) protocols like OPC-UA, real-time data ingestions via MQTT and REST, live dashboards, streaming analytics and advanced software- and firmware management of devices are now available to SAP Asset Performance Management customers as part of the EAC program.
To celebrate this milestone, we wanted to share a series of how-to guides with you.
In this guide it will be demonstrated how a device can be easily connected to the embedded IoT Platform (Cumulocity) and allocate their timeseries data to assets in SAP Asset Performance Management. It can be seen as a retrofit case where a smart sensor is added and can be attached and correlated to existing assets.
If you are looking for a more advanced way to connect industrial machines and devices to SAP Asset Performance Management, stay tuned for the next guide where we will leverage OPC-UA. We will also dive into applications for Streaming Analytics, how they work differently than existing APM rules and how to combine the strengths of both analytics engines for best results.
Prerequisites
To follow this guide, the following prerequisites must be fulfilled:
- You have access to an SAP Asset Performance Management environment with Embedded IoT platform*
- You have a smartphone (iOS or Android)*
Step-by-Step Guide
Download and Install the Cumulocity Sensor App
To get started, first of all we need a smartphone to install the Cumulocity Sensor App. It is available on the following stores:
- Google Play Store: https://play.google.com/store/apps/details?id=com.softwareag.cumulocity.iotcloudsensor
- Apple App Store: ‎Cumulocity IoT Sensor App App - App Store
Connect the App to Your Tenant
As a next step you can go to your provided Cumulocity Tenant → Cockpit App and hit the button “Connect smartphone”. A wizard will guide you through the steps to scan a QR code with the app. In the final step of the wizard, you can click on “Open Device” to jump to the dashboard that has been created for your smartphone.
Review Dashboard
In the default dashboard created for your smartphone, you can already see a Iot of useful things including:
- The location of your device
- Acceleration sensor values
- Luxometer of your camera
- Signal Strength and many more
Creating Indicators in SAP Asset Performance Management
With the data in Cumulocity you can now focus on assigning it to technical objects in SAP Asset Performance Management. In our case, we assume that the phone is attached to a “Cooling Water Circulation Pump” but you can assign it to any other asset of your choice. The acceleration sensor is used to detect vibration, similar to a retrofit sensor with a separate mobile uplink.
As a next step, we need to create indicators that represent our acceleration measurements. Follow the SAP documentation to create indicators for your selected asset.
Finally, copy the ID of the technical object you want to use for the further steps. It’s displayed under the name of the asset in the top left corner.
Assign Data Points to Indicators
Navigate to the Embedded IoT platform, via the “Manage Devices” tile on the SAP Asset Performance Management Launchpad. Within the platform, switch to the “Digital Twin Manager” application via the top right application picker.
Since assets in SAP Asset Performance Management are automatically synced with the Embedded IoT platform, we can search in the Digital Twin Manager for the technical object ID you have copied in the last step to find the corresponding asset in Digital Twin Manager.
Select the asset and navigate to the “Data points” tab. Here you see all indicators as data points. Click on “Link source” and select the data point of your smartphone and demonstrate it on the screen below. Repeat the steps for the two other data points.
After successful assignment, the measurement data will be made available within SAP Asset Performance Management.
Review data in SAP Asset Performance Management
Back in SAP Asset Performance Management, we can navigate to our selected technical object and check if data is already available.
To view the indicators in SAP Asset Performance Management, select them for monitoring like demonstrated below.
Great, you have the data of your retrofit sensor successfully assigned to your technical object and can leverage SAP Asset Performance Management to use it for further use cases.
Conclusion & Next Steps
This guide demonstrated how you can quickly integrate a device to Embedded IoT powered by Cumulocity and assign its measurement data to an existing technical object in SAP Asset Performance Management.
In the next guide, we will use OPC-UA to integrate an industrial device to Cumulocity with multiple data points and assign it to an asset.
