Use Cases
- PLC import substitution — replacing Siemens S7-300/400 and Schneider Modicon M340 in existing APCS. ST and FBD logic is converted to IEC 61499 without full redesign.
- Oil & Gas APCS — pump unit control: PID pressure regulation, emergency interlocks via Passer-T current protection, archiving in Strix.
- Manufacturing — sequencer control of production lines with AI8/DO16 modules and MES data exchange via OPC UA.
- Energy — substation automation: CAN network of secondary devices + MQTT telemetry to dispatch center.
