FLEX_LOAD_ADAPTER
Flexible-load adapter: sheddable capacity above a process floor, maximum shed duration, minimum-restore payback lockout with a countdown, and shed-verification supervision.
When to use it
Use FLEX_LOAD_ADAPTER when a controllable load — chiller plant, batch process, resistive heating, a data-hall power cap — is offered to a microgrid or demand-response programme, and the offer must respect the process's own floor, its maximum shed duration and the recovery time it needs before it can be shed again.

Supervised control write
FLEX_LOAD_ADAPTER commands a real actuator. It is written to sit underneath your own interlock, permissive and protection logic — not to replace it. Commission it as you would any control block you wrote yourself.
