I use the Simulink® Desktop Real-Time™ software drivers for my I/O modules. I see warning and error messages about missing software during model builds.
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 their 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.
To resolve warning or error messages issue from third-party vendor software, 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.
