4.3 Digital Input Setup Window
The purpose of the Digital Input Setup window is to configure the routing of NI 9411 digital input channels and four
internally generated digital PWM signals to various destination functions of the DI Driver System. The window also
shows the status of each NI 9411 digital input.
There are twenty destination functions which can be assigned a digital input or internal PWM signal source. There
are up to sixteen digital signal sources.
The Crank, Cam, and Encoder destinations are always applicable. The PFIX destinations are only applicable if a
PFI Driver module is inserted in its
. The number of applicable DI Driver module channel destinations
depends on the number of DI Driver modules available in the system and the slots in which they are inserted. For
example, if there are two DI Driver modules inserted in the DI1 and DI2 slots, then only destinations DI1_XXX
and DI2_XXX are applicable. If there is only one DI Driver module inserted in the DI4 slot, then only destinations
DI4_XXX are applicable. Systems using the cRIO-9076 chassis will only have one slot assigned for a DI Driver
module and the destinations associated with DI2 – DI4 will not be applicable.
The number of applicable digital signal sources depends on the NI 9411 digital input modules inserted in the system
and the slots in which they are inserted. If there are two NI 9411 modules inserted in the
twelve digital input sources are available. If there is only one NI 9411 module inserted in the 9411_1 slot, then only
