Hello SIOS Forum Community, The direct connection and integration of SIMATIC controllers to MES and ERP systems (e.g. SAP) is becoming increasingly important. We regularly receive enquiries about how plant data, e.g. from a SIMATIC controller, can be communicated directly to SAP via an existing company network. The SAP system supports different communication mechanisms and standards for connection to the process level. Due to the existence of the PROFINET interface as a standard interface in the SIMATIC S7-1200/1500 system family, the connectivity of this controller is also evolving. In particular, in addition to the PROFINET telegram (RT/IRT), the PROFINET interface provides a range of application protocols from the IT sector, which can be used on the basis of Ethernet and TCP/IP for direct connection of the PLC to the ERP level. In parallel to the SIMATIC controller, HMI systems are usually also placed in a plant-near environment. With the introduction of the new SIMATIC HMI system WinCC Unified, there are also new solution options for creating a direct connection to an ERP system such as SAP with regard to the connection to IT and OT systems. Below is an overview of the available communication services of a SIMATIC S7-1500 controller and the possibilities of our HMI systems using the new WinCC Unified Comfort Panel as an example, which could be used to connect to an SAP system. 1. SIMATIC S7-1500 Controller Available communication services for possible connection to an SAP system:
2. SIMATIC WinCC Unified Use of a SIMATIC HMI Unified Comfort Panel as an edge device and communication to SAP via the edge app "Node-RED" and an SAP node provided by SAP. Important note! Since no direct SAP drivers are available in the above-mentioned Siemens products, the compatibility with regard to the type and scope of use should be additionally checked with the manufacturer SAP. Therefore, all information is not guarantee Best regards, SIMATIC International Technical Support Hub |
