Starting Modules

TwinCAT C++ modules can be started in two ways:

• TwinCAT Loader: The TwinCAT Loader starts the TwinCAT module.
• The TwinCAT Loader requires a signature with TwinCAT user certificate.
• This option is mandatory for encrypted modules.
• The TwinCAT Loader is required for the versioned C++ projects.

Via System -> TcCOM Modules -> Class Factories tab you can see whether the TwinCAT Loader or the operating system is used:
