Three beats:
- Metaphor — a PLC/DCS controller is a computer (OS, apps, network, APIs, security); downtime in OT costs real money.
- Lifecycle mismatch — computer 5–7 yr, software 8–10 yr, I/O 20–30 yr, copper 80–100 yr; tight coupling forces expensive wire moves on every upgrade cycle.
- Components at a glance — DCN, OCF (OPC UA, TSN), ACP, orchestration, apps; loosely coupled, highly cohesive, separation of dependency.
Full component list in the companion: DCN, OCF, OPC UA, TSN, ACP, CAS, system management, engineering, cyber, orchestration, virtualization, apps (control + new possibilities).
The standards deep-dive is E05.
