Models can have multiple digital input blocks for one physical board. In this case, the Simulink Real-Time environment executes the blocks based on their sorted order as determined by the Simulink software.
Each board has one set of static digital I/O ports. You can independently configure each port to be input or output.
A digital input block can share channels with a digital output block. In this configuration, the input block reads the last value written to the digital output block on the shared channels.

Enter numbers between 1 and 32 to select the digital input lines used with this port. This driver allows the selection of individual digital input lines in arbitrary order. The number of elements defines the number of digital lines used.
For example, to use the first eight of the digital inputs for one port, enter
Number the lines beginning with 1 even if this board manufacturer starts numbering the lines with 0.
Enter the base sample time or a multiple of the base sample
-1 means sample time is inherited).
If only one board of this type is in the target computer, enter
locate the board.
If two or more boards of this type are in the target computer, enter the bus number and the
PCI slot number of the board associated with this driver block. Use the format
To determine the bus number and the PCI slot number, type:
