Connecting an SAP system to devices and machines in a system environment can be realized quite simply with the help of interfaces. With the RFC, BAPI, IDoc, SOAP and REST interfaces, various solutions are available for different requirements. Regardless of which interface is used, the result is the same: your SAP system communicates with your system environment.
For setting up the SAP connection, it is possible to use software such as OPC Router. All the key interfaces are provided, and the connections to devices and machines can be set up in a graphical user interface using drag & drop. In practice, it is possible to distribute SAP data to other systems or transfer data to the SAP system with little effort and no programming knowledge. Networking of this kind makes Industry 4.0 a reality.
