Library

xPC Target Library for Keithley Metrabyte

Note

The analog output range of this board is set -10 to +10 volts.

Scaling Input to Output

Block Parameters

Channel vector

Enter numbers 1 or 2. This driver allows the selection of individual D/A channels in any order. The number of elements defines the number of D/A channels used. For example, to use both of the analog output channels, enter

[1,2]

Number the channels beginning with 1 even if the board manufacturer starts numbering the channels with 0.

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 used for all channels. 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.

Initial value vector

The initial value vector contains the initial voltage values for the 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 the initial value for all channels. The channels are set to the initial values between the time the model is downloaded and the time it is started.

Sample time

Base sample time of a multiple of the base sample time.

PCI Slot (-1:autosearch)

If only one board of this type is in the target PC, enter

-1

to automatically locate the board.

If two or more boards of this type are in the target PC, 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
