  Software integration of diverse data acquisition and timing hardware devices in diagnostics applications is very challenging. While the implementation should manage multiple hardware devices from different manufacturers providing different applications program interfaces (APIs), scientists would rather focus on the high level configuration, using their specific environment such as EPICS, Tango, the ITER Real-Time Framework or the MARTe2 middleware. The Nominal Device Support (NDSv3) C++ framework, conceived by Cosylab and under development at ITER for use in its diagnostic applications, uses a layered approach, abstracting specific hardware device APIs as well as the interface to control systems and real-time applications. ITER CODAC and its partners have developed NDS device drivers using both PXIe and MTCA platforms for multifunction DAQ devices, timing cards and FPGA-based solutions. In addition, the concept of an NDS-System encapsulates a complex structure of multiple NDS device drivers, combining functions of the different low-level devices and collecting all system-specific logic, separating it from generic device driver code.
