Block Parameters

Channel vector

Enter a vector of numbers to specify the digital output channels.

For example, to use the first and second analog digital output channels enter

[1, 2]

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 8.

Reset vector

The reset vector controls the behavior of the channel at model termination. Enter a scalar or a vector that is the same length as the channel vector. If you specify a scalar value, that setting is replicated over the channel vector. If you specify a value of 1, the corresponding channel is reset to the value specified in the initial value vector. If you specify a value of 0, the channel remains at the last value attained while the model was running. For example, if Channel vector is [1 2] and the Reset vector is [1], the action taken will be the same as if Reset vector was set to [1 1]. Both channels will be reset to their initial values when model execution is stopped.

Initial value vector

The initial value vector contains the initial voltage values for the digital output channels. Enter a scalar or a vector that is the same length as the channel vector. If you specify a scalar value, that value is replicated as initial value over the channel vector. The channels are set to the initial values between the time the model is downloaded and the time it is started. When model execution is stopped, the corresponding position in Reset vector is checked. Depending on that value, the channel is either reset to the initial value or remains at the last value attained while the model was running. For example, assume that Channel vector is [ 1 2 ], Reset vector is [1 0], and Initial value vector is [0 1]. On initial download, channel 1 is set to off and channel 2 to on. When the model is stopped, channel 1 resets to off and channel 2 remains at the last value attained.

If the Initial value vector value is greater than 0.5, the corresponding digital output port is turned on, otherwise it is turned off.

Sample time

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

PCI slot

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')
