edgeConnector Siemens

Software module to connect SIMATIC S7 PLCs with Industrial IoT Applications

edgeConnector Siemens connects Siemens SIMATIC S7-300/400, and S7-1200/1500 controller and provides access to data via an OPC UA server interface. As a docker container, it offers flexible deployment options, for example on devices running Azure IoT Edge or AWS IoT Greengrass.

The application is easy to configure locally via a built-in Web interface. It can also be managed remotely via its REST API. Configuration is flexible and includes fine-tuned security settings (e.g. role based access rights for OPC UA client applications).

As a first strategic extension of Softing’s dataFEED product family into virtualization- and container technology, the new product leverages Softing deep experience with brownfield connectivity and OPC UA technology, and makes it available for new and highly efficient IoT solution architectures.
