Ohjearvona

Ohjearvona is a Finnish term used in technical contexts to denote a target or setpoint value in control systems and automation. The word combines ohjaus (control) and arvo (value), with the suffix -na that marks a role or state, yielding a rough translation of “as a control value” or “as the setpoint.” In practice, ohjearvona appears in sentences that refer to the role of a value within a control algorithm and its use as a parameter guiding system behavior.

Usage and syntax in technical documentation and software describe ohjearvona as a nominal phrase that designates the parameter a controller aims to achieve. It is encountered in planning control strategies, PLC programming, and process control descriptions. The term is often discussed alongside related concepts such as arvo (value) and ohjaus (control); its exact meaning can vary slightly between authors or sectors, with some writers emphasizing the functional role of the value in the control action.

Example usage might look like: “Ohjearvona asetetaan prosessin säädön tavoitteeksi, ja järjestelmä pyrkii ylläpitämään sen arvoa.” This illustrates the notion of designating a target value that the control loop seeks to maintain. Ohjearvona remains a specialized term whose prevalence is strongest within formal engineering and automation texts, rather than everyday Finnish language. Related terms include ohjaus, arvo, and setpoint concepts used in regulation and PID control literature.
