Block

Mask

Description

The Op NI6602 DigitalIn block monitors the digital I/O lines of the National InstrumentsNI6602 card.

The block can monitor a subset of the 32 available digital I/O lines. Note that lines 0 to 7 are reserved for digital I/Os, while lines 8 to 31 are shared with 6 of the timers of the card. Please refer to the connector pin assignments below to avoid conflicts.

Parameters

Bus TypeSelect the bus type (PCI or PXI) of the target node in 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 [0-31], 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) on 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.
