settable

Settable is an adjective describing something that can be set, configured, or adjusted to a desired value by a user or by software. The term is common in engineering, electronics, and software development to indicate that a parameter, setting, or component is not fixed but can be modified within defined limits.

In hardware and electronics, settable components include adjustable resistors or potentiometers, programmable timers, and devices that expose user-accessible controls or DIP switch configurations for selecting operating modes or timing. These elements are designed to be tuned or calibrated during setup or maintenance.

In software, settable refers to values that can be assigned at runtime or design time through user interfaces, configuration files, or programming interfaces. Many programming languages provide set accessors for properties, allowing code to assign values to an object's attributes. Settable parameters are often exposed through interfaces or APIs to enable customization and adaptability.

Settable values are typically constrained by validation rules, ranges, units, and safety limits to prevent invalid configurations. The concept emphasizes user or system control over behavior, while ensuring reliability and safety.

Related terms include configurable, adjustable, and programmable. The contrast is with fixed, hard-coded, or non-configurable elements.
