Maintaining compatibility between LabVIEW 2018 and LabVIEW 2021 requires understanding how National Instruments updated its product lifecycle and software deployment during this three-year window. Software Bundling and NI Package Manager
Elias was running with the Control Design and Simulation Module. It was a robust workhorse, trusted by engineers for decades.
Sarah dragged a onto the diagram. In 2018, configuring this for a specific timing source was a dive into buried menus. In 2021, the configuration was intuitive, with better support for multi-rate diagrams.
As the progress bar crept forward, Elias felt like a mechanic swapping a vintage engine for a modern turbine. When the 2021 environment finally bloomed to life, he imported his legacy code. The transition wasn't just aesthetic. He opened the Simulation Loop
Route the plant output back to the negative terminal of your initial Summation block.
If you need a (e.g., cruise control simulation, inverted pendulum, or real-time deployment), let me know and I’ll provide the exact block diagram steps for your version (2018–2021).
Build mathematical models (transfer functions, state-space) from measured stimulus and response data.
The 2021 version added Secure Shell (SSH) version of FTP (SFTP) functions, critical for secure deployment to real-time targets.
The installation and requirements for the module evolved significantly between 2018 and 2021, reflecting changes in NI's overall software strategy. It is critical to note that the module was not a standalone program; it was an add-on that required a compatible version of LabVIEW installed first. The table below summarizes key installation and requirement details for the 2018 and 2021 versions.
Moves almost exclusively toward NI Linux Real-Time . If you are migrating a 2018 simulation code base containing custom C/C++ DLL nodes to 2021, you must recompile those binaries using the updated Linux toolchain. Step-by-Step Workflow: Building a Closed-Loop Simulation
Solve linear and nonlinear differential equations using various solver methods, such as Runge-Kutta or Euler .
Design plant in Simulink → export as FMU (model exchange) → import to LabVIEW CD&SM → design controller graphically → deploy to cRIO.
Unlike standard LabVIEW loops (like While Loops or For Loops), the Simulation Loop executes using ordinary differential equation (ODE) solvers.

He hit 'Run.' In the 2018 version, the virtual drone had wobbled under heavy wind gust simulations. Now, utilizing the improved multithreading of the 2021 engine, the simulation stayed rock-solid. The digital twin on his screen hovered with eerie precision, reacting to "virtual storms" in real-time.
