| − | == Code snippets ==
| |
| − |
| |
| − | Code snippets are simple, isolated use-cases that illustrate the use of Eclipse BaSyx. They provide focused recipes that document the intended use of the BaSyx SDK and our reference implementations of Industrie 4.0 middleware components. To keep functional examples simple, code snippets only address selected aspects of Industrie 4.0 implementations. Selected snippets provide a page with documentation. For all snippets, links to executable source code files in the git repository are provided. The source code may contain required drivers and stubs for running the code, as well as testing routines that validate the results of the execution.
| |
| − |
| |
| − | Please keep in mind that not all features are available with all language versions of Eclipse BaSyx. Snippets therefore may only be available for selected languages.
| |
| − |
| |
| − | The code for the snippets is available via the Eclipse BaSyx GIT repository:
| |
| − | * For Java, the code is located in the basyx.example project in package org.eclipse.basyx.examples.snippets

| − | === Virtual Automation Bus (VAB)===
| |
| − |
| |
| − | The Virtual Automation Bus provides end-to-end connection capabilities. The VAB uses gateways to connect network technologies into one virtual, and fully connected network. The network consists of objects, e.g. Asset Administration Shells and sub models that are accessible through unqiue IDs. The following code snippets illustrate VAB operations and the use of the Virtual Automation Bus.

| |
| − |
| |
| − | These code snippets illustrate Asset Administration Shells in context of HTTP servers. It is common to deploy an Asset Administration Shell to the IT to ensure its presence when a device fails. HTTP servers are a viable host for Asset Administration Shells. The following code snippets illustrate the dynamic creation of an Asset Administratuion Shell, its transfer, and its use from Industrie 4.0 applications.

| − | ===AAS Sub models===
| |
| − |
| |
| − | Asset Administration Shell sub models may be distributed through the network. While an AAS resides on the IT and remains accessible in case of device failures, sub models may be distributed. Sub models containing static data or information about devices that needs to remain available in case of device failure may be hosted on the IT as well; sub models containing live data may be hosted on devices, and possibly on products. The following code snippets illustrate the creation, transfer, hosting, and use of AAS sub models.

| − | ===AAS Sub model providers===
| |
| − |
| |
| − | Eclipse BaSyx provides pre-created AAS sub model providers. These servlets connect existing data sources, such as textual configuration files and SQL data bases into Industrie 4.0 environments as AAS sub models. BaSyx sub model providers are configured with a configuration API and do not require programming knowledge to integrate data sources into Industrie 4.0 environments as AAS sub models.

| |
| − |
| |
| − | Asset Administration Shell sub models may contain dynamic properties and operations. Dynamic properties are properties whose values are generated dynamically at runtime. This may happen for example periodically, or whenever a specific information is requested. Dynamic operations are operations that may be updated at runtime. The following code snippets illustrate dynamic sub model properties and operations.

The following BaSys 4.0 scenarios document application scenarios and functional examples of the Eclipse BaSyx middleware. Application scenarios illustrate how common Industrie 4.0 challenges are addressed with Eclipse BaSyx. They describe architecture concepts and implement running example scenarios that illustrate the implementation of Industrie 4.0 components and inter-component interactions. Functional examples provide a focused documentation to developers that explain one function of eclipse BaSyx. They provide concrete recipes that illustrate the use and the application of Eclipse BaSyx components.
