IntervalZero’s RTX® is a real-time extension for the Microsoft Windows operating systems: Windows 2000, Windows XP, Windows 2003 Server and Windows Vista. The CIFX driver for RTX allows access to Hilscher netX based components (CIFX/COMX/netPLC/netJACK 100) with the same functionalities as those used by the CIFX Windows driver. It consists of a dynamic link library (RTDLL) that contains the CIFX toolkit. User programs accessing the driver functions by using LoadLibrary() and GetProcAddress() requests.
