OPC UA Server & MQTT Publisher Gateway for SIMATIC S7 Controllers

Access Siemens PLC Data & integrate data with OPC UA in higher level management systems

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

In addition, uaGate SI also offers MQTT Publisher functionality, enabling 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.
