I would recommend using one event for each line if each line's
interrupt drives a specific function so that you do not have to do
further processing to determine the location of the interrupt.
The PC-DIO-24 uses W2 and W3 to select the interrupt level and select
the interrupt enable line respectively. Appendix D of the
PC-DIO-24/PnP24/PnP User Manual
provides further instructions. The Traditional NI-DAQ (Legacy) C
Reference Help provides further information on the parameters to
configure the DAQ Event, this help file is located at Program Files
>> National Instruments >> NI-DAQ >> nidaqpc.chm.
