Description

The National InstrumentsNI671x cards feature analog inputs, analog outputs, digital I/O lines and counters. This block monitors a user-defined subset of the 8 digital I/O lines, and configure these channels in input mode.

This block supports a list of PXI and PCI compatible cards selectable in the block parameters menu.

Parameters

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 specified in the channel list parameter. The output width of the block must be equal to the number of entries in the channel list parameter.

Characteristics and Limitations

Cable

The SH68-68- EP cable (P/N 184749C-01) from National Instruments must be used.
