SAP IoT Integration: The SAP Internet of Things solution (SAP IoT) is a collection of services, apps, and UI templates that help you modeling digital twins of real-world objects that you want to monitor, track, or analyze.

Introduction

The SAP IoT processing service is configured through the Message Processing API as described in section Create a Configuration for the SAP IoT Processing Service or you can use the Internet of Things Service Cockpit as described in section Create a Configuration in the Internet of Things Service Cockpit documentation.

Applicability of This Documentation

This documentation describes the functions of the Device Connectivity feature of SAP IoT.

This Device Connectivity documentation is only relevant to you if you have a new SAP IoT license under which the Device Connectivity feature is an integral part of SAP IoT.

You can find out which type of license you’re using by going to your SAP BTP subaccount in the SAP BTP Cockpit and looking under Subscriptions.

• If you’re subscribed to SAP IoT (new license: oneproduct application plan), this documentation is relevant to you.
• If you’re subscribed to SAP Leonardo IoT (older license: standard service plan), this documentation is not relevant to you. Please refer instead to the documentation for SAP IoT services for SAP BTP for the Cloud Foundry Environment, which explains how to use this older Internet of Things service for device management.

Architecture

The following figure provides an overview of the architecture.

Device Connectivity

The Gadget Network Programming interface that gives usefulness to the association of IoT gadget and its lifecycle the executives. This incorporates the meaning of the message design for measures and orders, setup of the convention to be utilized for information transmission and setting up the qualifications for getting to Gadget Availability.
Gadget Network can be utilized to test the relating REST APIs. An itemized portrayal of the gadget model can be found in the segment Gadget Model. For more data, kindly allude Make a Gadget Model utilizing Programming interface.

IoT Gateway Cloud and IoT Edge

The IoT Gateway is available in the cloud and can be deployed at the edge. It was originally available as IoT Edge platform, but is now available as a new product, Edge Gateway Service,since November 2021.

SAP suggests involving Edge Entryway Administration for new ventures. It is accessible as a piece of SAP IoT Edge and can be remotely sent to the edge from the SAP cloud. SAP IoT Edge additionally considers conveying custom programming written in any language involving any system to the edge as Docker holders. The Augmentation Administration can handle IoT sensor readings at the edge when they are gotten by the Edge Door Administration.

The more established IoT Edge Stage can be introduced at the edge and gives connectors to arrange assembly and syntactic convention standardization. Its usefulness can be broadened utilizing IoT Edge Stage SDK.

Device Model

The device model for Device Connectivity consists of six entities: Gateway, Device, Sensor, Sensor Type, Capability, and Property as shown in the following graphic.

To be able to distinguish between commands (messages sent to the device) and measures (messages sent from the device) the relationship between SensorType and Capability can be attributed.

Typical Device Connectivity Workflow

SAP IoT Device Connectivity starts with Device Model creation.

In order to create digital twin of physical asset, such as silos, in the SAP system, Device entity is onboarded. This is done by creating a Device Model, which includes four entities: Capability, Sensor Type, Device, and Sensor.

Step 1: Create Capabilities and Sensor Types

To start with Device Connectivity, you need to create Capabilities and Sensor Types using the Device Connectivity API.

• Create new Capabilities
• Create new Sensor Type

Step 2: Onboard a new device

Next step is to onboard Device into the system using the Device Connectivity API.

• Create a Device
• Generate a certificate and put it onto the device
• Create a Sensor
• Update device firmware to send data expected by the sensor from the device to the Device Connectivity endpoint

Step 3: Set up End-to-End Data Ingestion

Once you create device and entities, you need to set up data ingestion.

• Send Data with MQTT (
• Send Data with REST
• Send Commands with MQTT

Step 4: Read Measures

You can read the Measures received to check that they arrive correctly.

• Check Incoming Data

Step 5: Handle Security Issues During Operation and Monitoring

If you have reason to believe that a device may have been compromised, you must revoke its certificate. For description of this task, see Certificate Revocation.

Step 6: Create and Manage Custom Properties for Device

You can create and manage Custom Properties for the Device associated to the given ID using the Device Connectivity API:

• Add Custom Properties
• Edit Custom Properties
• Delete Custom Properties
