CODESYS and OnLogic are showing what “hardware-independent PLC” actually looks like in the real world: a soft PLC with functional safety running on an OnLogic industrial PC (Debian Linux with a real-time patch), with Virtual Control and Virtual Safe Control containerised for deployment at scale.
In this walkthrough we cover:
What a soft PLC is, and why determinism matters
How CODESYS approaches safety on standard compute (including the move to hardware-independent safety up to SIL 3)
Why OnLogic industrial hardware matters for sub-millisecond cycles
Security implications, consolidation, and reducing attack surface
The demo stack: EtherCAT, FSoE (FailSafe over EtherCAT), and distributed safe I/O
If you’re building factory automation systems and you care about real-time behaviour, safety, and scalable deployment across multiple sites, this is worth watching.
