Flat Sequence Structure Design Patterns in LabVIEW
Overview of the Flat Sequence Structure The Flat Sequence Structure in LabVIEW is a dataflow-based programming construct that enforces sequential execution of code. It consists of one or more frames, each executing in order from left to right. Unlike the Stacked Sequence Structure, all frames are visible simultaneously, making debugging and maintenance easier. Key Characteristics Common Design Patterns Using Flat Sequence…

Functional Global Variable (FGV) Design Patterns in LabVIEW
A Functional Global Variable (FGV) is a well-known design pattern in LabVIEW that allows data to be stored and accessed in a controlled manner, avoiding the problems associated with traditional global or local variables. It is implemented using a non-reentrant, uninitialised shift register in a While Loop inside a non-executing (single-run) While Loop within a LabVIEW VI. FGVs provide a more robust alternative to…

State Machine Design Pattern in Labview
State Machine Design Pattern in LabVIEW The state machine is one of the most commonly used design patterns in LabVIEW, particularly for applications that require decision-making, sequential control, or event-driven behaviour. It is well suited for processes that have a defined number of states and transition conditions. 1. What is a State Machine? A state machine is a programming…

Actor Framework architecture in Labview
The Actor Framework (AF) in LabVIEW is a sophisticated design pattern that is part of LabVIEW’s Object-Oriented Programming (OOP) environment. It provides a modular, scalable way to build complex applications where components (called “actors”) operate independently and communicate with each other through asynchronous messaging. This approach enables concurrent execution, making it ideal for large applications requiring multiple…
