Product overview
PLC & CNC connectivity
Compact gateway for exposing documented SIMATIC S7 controller data through OPC UA and MQTT.
Direct S7 accessAcquire documented S7 data without adding an OPC server inside the controller.
Information interfacesExpose selected data through the integrated OPC UA Server or MQTT Publisher.
Controller boundaryOptimized blocks and TLS apply to compatible S7-1200/1500 configurations, not every S7 family member.
Lifecycle planningSofting states these functions are included in SDEX Suite; review new designs against SDEX.
Lifecycle / positioning: Installed-base / lifecycle page. For new data-integration projects, review current SDEX Suite support and migration options first.
