Problem:
I would like to create a LabVIEW user interface for a simulation model that I developed using The MathWorks, Inc. Simulink® application environment. Do I need the LabVIEW Real-Time Module in order to run this simulation?

Solution:
Technically, you do not need the LabVIEW Real-Time Module to use the Simulation Interface Toolkit (SIT) in LabVIEW to run a simulation created using the Simulink® application environment on a Windows machine. You will need the following:

Model—The combination of blocks that make up the simulation. Models contain inputs and outputs that send and receive data. A model is built using The MathWorks, Inc. Simulink® application software.
Host VI—The VI that you use as a user interface to the model. In the host VI, you can use front panel controls to manipulate model parameters and display model outputs.
SIT Server—The software that transmits data between the host VI and the model using TCP/IP. You must launch the SIT Server, which starts automatically when you launch The MathWorks, Inc. MATLAB® or Simulink software, before running a simulation. By default, the SIT Server runs on port 6011.
Host Computer—The computer on which you run the host VI. The host computer must be a PC running Windows NT, 2000, or XP.
Execution Host—The computer on which you run the MATLAB® application software, the SIT Server, and the simulation itself. The execution host can be the host computer or a Windows computer on the same TCP/IP network as the host computer.

In the SIT Connection Manager (found in LabVIEW in the Tools pull down menu), you will need to select either Simulation Environment for the localhost or Driver VI on Localhost. If you would like to run your model deterministically, you will need a real-time execution target. To interface SIT with your real-time execution target, you will need the LabVIEW Real-Time Module.
