PAEFS — Process Automation, Energy and Factory Systems
Process Automation Energy and Factory Systems — bridges PADIM's process-instrumentation model with Machinery's factory model. Four enums, no DTOs.
OPC UA companion specification bridging PADIM (process-side instrumentation) and Machinery (factory-side equipment). PAEFS provides the cross-cutting vocabulary needed when a single asset is both a "process instrument" (PADIM) and a "machinery item" (Machinery) — common in pharmaceutical, food and beverage, specialty chemical lines.

Notable enums
The four enums classify cross-cutting attributes — equipment suitability for energy / process / factory contexts.
