The transition of a Programmable Logic Controller (PLC) cabinet from a controlled factory floor to a volatile plant environment represents a critical milestone in factory automation. While a Factory Acceptance Test (FAT) validates standalone hardware compliance under ideal conditions, it cannot replicate real-world process dynamics. Therefore, deploying an industrial automation system requires a rigorous Site Acceptance Test (SAT) to verify total loop integrity, field wiring wiring metrics, and process control parameters before final customer handover.
