Beckhoff TwinCAT OPC UA Server Configuration
Stream real-time PLC variables from Beckhoff CX Industrial PCs and TwinCAT 2/3 (TF6100) directly into MQTT, Sparkplug B, and Timeseries databases without Windows ADS DLLs.
TwinCAT TF6100 Integration Highlights
- Symbol-Based Addressing: Reference TwinCAT GVL and MAIN program variables directly via
ns=4;s=MAIN.fMotorSpeed. - High-Frequency Telemetry: Deterministic 10ms+ subscription publishing with zero garbage-collection jitter.
- Cross-Platform Linux/Docker: Run opcua2mqtt on TwinCAT/BSD, Linux IPCs, or co-located Docker containers.
