Prosessblokker

Prosessblokker is a term used in Norwegian and Danish contexts to describe modular units within a process model or automation system. A prosessblokke typically represents a single operation or subprocess within a larger workflow. Each block has defined inputs and outputs and may carry parameters, state information, and control logic. In graphical representations such as block diagrams or process simulations, blokker are linked by signals or material streams, forming a data or material flow through the system.

In engineering contexts, prosessblokker appear as unit operations in chemical engineering, process control, mechanical systems, and other industrial processes. Examples include a reactor block, a mixer block, a heat exchanger block, a separator block, or a control block that computes a setpoint. They support design, optimization, and simulation by enabling modular modeling and reuse of components.

In software and business process contexts, the term is sometimes used to describe functional units within a workflow or data-processing pipeline. Here, prosessblokker encapsulate logic such as data transformation, validation, routing, or decision making, and are connected in sequences, branches, or parallel paths.

Standards and related concepts: Similar ideas appear under function blocks in IEC 61499 for industrial automation, and block-diagram notations are common in process-flow methodologies such as P&ID diagrams, BPMN, and general flowcharts, where blocks correspond to subprocesses.

Advantages of using prosessblokker include modularity, clarity, ease of testing, and reusability. Limitations involve potential oversimplification, integration challenges, and the need for consistent semantics to ensure interoperability between blocks and systems.
