PCI-PDISO8 Digital Input block
Simulink® Real-Time™ Library for Measurement Computing™
I/O Module Input
Block Output Data Type
Low (opto off) = 0.0
The input is rectified before being applied to the opto isolator on the input. Without an additional input current limiting resistor, the opto turns on when volts.
Enter numbers between 1 and 8 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 all of the digital inputs, enter
Number the lines beginning with 1 even if this board manufacturer numbers the lines beginning with 0.
This vector controls the 5 ms noise filter. It is the same length as the channel vector. A value of 1 turns the filter on, and a value of 0 turns the filter off. If you specify a scalar, this value is replicated across the channel vector.
From the list choose
A because this board
only has eight channels.
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:
