Block Parameters

Channel vector

This parameter is a combined Channel vector and Range vector. The number of elements defines the number of D/A channels used.

Range vector

Enter a range code for each of the D/A channels used. This driver allows a different range for each channel with a maximum of 2 channels.

The following table is a list of the ranges for this driver and the corresponding range codes. The D/A specific jumpers on the board have to be set as required for the ranges entered.

Input Range (V)

Range Code

0 to +10

10

0 to +5

5

For example, if the first channel is 0 to + 10 volts and the second channel is 0 to +5 volts, enter

[10,5]
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.

Initial value vector

The initial value vector contains the initial voltage values for the input 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. If you provide an out-of-range value for a channel, that value is adjusted to be within the range defined by the parameter Range.

Sample time

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

Base address

Enter the base address of the board. This entry must correspond to the DIP switch setting on the board. For example, if the DIP switch setting is 300 (hexadecimal), enter 0x300.
