driftsval

Driftsval is a term used in Swedish-language technical discourse to describe the process of selecting the operating mode or mode of operation of a system, device, or process. The word combines drift, meaning operation or running, with val, meaning choice or option. In practice, driftsval refers to the decision or mechanism that determines which predefined state the system should assume at a given time.

Usage and scope

Driftsval appears in engineering, automation, energy management, and information technology contexts. It may govern transitions between modes such as normal/automatic, manual, maintenance, energy-saving, standby, or emergency. In building management, for example, a driftsval decision can switch HVAC and lighting systems between energy-efficient and normal operation based on occupancy or external conditions. In industrial automation, it can select control strategies or setpoints for different production phases. In software and hardware configurations, driftsval can denote selecting a run mode, configuration profile, or safety level.

Implementation considerations

Implementing a driftsval typically involves a state-based or rule-driven mechanism, often implemented as a state machine or control logic with safety interlocks and audit logging. Changes may be triggered by sensors, operators, or automated decision rules, and they should be reversible and well-documented to ensure traceability.
