Block Parameters

Board type

Select the specific board type from the list provided.

Channel vector

Enter a vector of numbers to specify the output channels. For example, to use the first and third digital output channels, enter

[1 3]

The channel numbers can occur in arbitrary order. Number the channels beginning with 1 even if this board manufacturer numbers them beginning with 0. The maximum allowable channel number is 16, except for the PD2-AO and PDXI-AO series. For those boards, the maximum channel number is 8.

Reset vector

The reset vector must be the same length as the channel vector. It contains values of 0 or 1. This parameter controls the behavior at model termination. A value of 1 causes the corresponding channel to be reset to the value specified in the initial value vector. A value of 0 causes the channel to remain at the last value attained while the model was running.

Initial value vector

The initial value vector must be the same length as the channel vector. It contains the initial values (0 or 1) for the output channels. The channels are set to these values between the time the model is downloaded and the time it is started.

Sample time

Enter the base sample time or a multiple of the base sample time (-1 means sample time is inherited).

PCI slot (-1:autosearch)

If only one board of this type is in the target computer, enter -1 to 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 [BusNumber,SlotNumber].

To determine the bus number and the PCI slot number, type:

tg = slrt;
getPCIInfo(tg, 'installed')
