NI-ModInst is a component that you can use to query information about National Instruments Modular Instruments installed in your system. NI-ModInst provides a programmatic way to determine the number, names, models, and other attributes of devices in your system that are supported by a specified driver. You can use the NI-ModInst API in applications you develop using LabVIEW, LabWindows™/CVI™, Measurement Studio, or C.

In general, you provide the name of a National Instruments instrument driver to NI-ModInst. Examples of instrument drivers include NI-SCOPE, NI-FGEN, and NI-DMM. NI-ModInst searches the system and finds all the devices that are supported by that driver. You can query NI-ModInst for the number of installed devices, the device names, product models, serial numbers, chassis numbers, slot numbers, bus numbers, and socket numbers.
