Simulink® Desktop Real-Time™ provides dedicated drivers for I/O modules. Some vendors can require the installation of vendor-specific software, even if you do not use this software. A warning or error message during the build or during execution can indicate this software installation requirement. Or, the I/O module fails to initialize.
If you encounter such instances, refer to the vendor documentation for vendor-specific requirements. If the hardware requires the installation of vendor software, install the vendor software on your computer.
