GAA-DX-145111:dataFEED uaGate SI: OPC UA and MQTT Gateway

uaGate SI makes data integration simpler than ever. The gateway supports the connection of Siemens SIMATIC S7-300, S7-400, S7-1200, and S7-1500 controllers and uses the OPC UA standard for simple and secure data integration of new and existing plants into higher-level management systems such as ERP, MES, or SCADA systems.

 

In addition, uaGate SI also offers MQTT Publisher functionality, which enables direct integration of PLC data into private or public IoT cloud applications on the IT side. The generic MQTT implementation supports the use of a large number of different cloud providers. Similar to the OPC UA standard, MQTT also supports various security mechanisms such as encrypted connections, certificates, and user authentication, thus contributing to a high level of data security.

 

With this functionality, uaGate SI is a compact, secure, future-oriented, and proven gateway for data integration.
