SPECIFICATION · BALANCE OF PLANT

I&C and SCADA
specification.

The supervisory layer that fuses all six balance-of-plant systems into one operator picture, with a fast protective tier beneath it and human decision authority above it.

DESIGN TARGET · NOT MEASURED PERFORMANCE

Figures on this page are engineering design targets and reference-architecture values, not measured results from operating hardware. They state what the design is being engineered to achieve. Verified performance data will replace them as systems are built and tested. Nothing here should be relied upon as a performance warranty.

Design basis
TIER 1

Protective — deterministic

Narrow, verifiable protective actions that cannot wait for a scan cycle or an operator. Deterministic by design and independently testable.

TIER 2

Supervisory — plant model

Trending, optimisation, and cross-system coordination. This is where the plant model lives and where most operator interaction happens.

TIER 3

Human — decision authority

Consequential decisions remain with a qualified human. The lower tiers exist to buy that human time and context, not to replace them.

ALARMING

Rationalised philosophy

One alarm philosophy across all systems. Priority means the same thing everywhere, or operators learn to ignore whichever system cries wolf.

Interfaces

Consumes data from all balance-of-plant systems over the plant I&C network and interfaces the machine/plasma controller at the balance-of-plant boundary only. Machine physics and plasma stability control remain with the machine builder — this layer supervises the plant around the device, not the device itself.
