Softing dataFEED edgeConnector Siemens is a containerized SIMATIC S7 connectivity module adding OPC UA Server and MQTT functionality to compatible Sensors and PLCs. The software can run as IoT Edge Module. After the deployment, it is possible to configure Southbound and Northbound communication via local GUI or REST interface.

For southbound communication it is possible to connect up to 20 Siemens S7-300/400 or S7-1200/1500 PLCs including optimized data blocks. The Namespace configuration is done by importing the STEP7/TIA Projects or simply browsing the variables of the PLC.

The northbound communication runs with standardized OPC UA communication for data integration into management systems like ERP, MES or SCADA or for data exchange with other docker containers like Microsoft OPC Publisher for cloud scenarios. In addition MQTT is available as protocol to connect MQTT Broker in local or cloud environments. The application supports security standards like SSL/TLS, X.509 certificates, authentication and data encryption. The container runs for 72h in demo mode. Fully activate the application via BYOL from Softing. This also requires the installation of the Softing floating license server.
