Description

The National InstrumentsNI6703 and NI6704 cards feature 16 voltage outputs and 8 digital I/O lines. The NI6704 card also features 16 current outputs. This block monitors the digital I/O lines and configures them as input channels.

Parameters

Bus TypeSelect the bus type (PCI or PXI) of the target node in this list.
Card TypeSelect the card model on this list.
PCI indexEnter the PCI index (see definition)of the card on the PCI (or PXI) bus.
Selection of channels used in inputEnter the vector of channel numbers to be monitored by this block. The channel numbers, in the range [0-7], can be entered in any order and must appear only once in the list.
Synchronizesee definition.

Inputs

This block has no inputs.

Outputs

At each calculation step of the model, the block returns the current values (0 or 1) of the I/O lines.

Only the values of the channels specified in the channel list parameter are returned and the outputs are in the order of the channel list parameter. The width of the outport of the block must be equal to the number of entries in the channel list parameter. Use a demux to connect individual outputs to the rest of the model.
