PNEM — PROFINET Energy Management
PROFINET Energy Management — energy-saving modes for PROFINET-attached devices. Four enums, five structured types. Depends on DI.
OPC UA companion specification for PROFINET Energy — the PROFINET-specific extensions for energy-saving modes on the network. A PROFINET device that supports pause / suspend / maintenance modes exposes those states through PNEM.
