Ruby-MM-1612 Analog Output block
Simulink® Real-Time™ Library for Diamond
I/O Module Output
Block Input Data Type
Enter a vector containing channel numbers between 1 and 16. This driver allows the selection of individual D/A channels in arbitrary order. The number of elements defines the number of D/A channels used. For example, to use the first and second analog output (D/A) channels, enter
Number the channels beginning with 1 even if this board manufacturer starts numbering the channels with 0.
Bank 1 consists of channels 1 to 8 and bank 2 consists of channels 9 to 16. The output range may be specified on a per-bank basis. These ranges must correspond to the jumper settings in header R4 on the board. See the board manual for details.
If you select a range of either
-5V to +5V or
to +5V for one bank, then it is not possible to select a
range of either
-10V to +10V or
0 to +10V for
the other bank. This is because jumper 5 in header J4 (On-Board Reference
Full-Scale Voltage Selection) affects all
channels, not just those of a single bank. See the board manual for
details. The following lists the allowed output voltage range combinations
for the two channel banks. B1 is
the first bank of channels, B2 is
the second bank of channels.
This driver supports the Adjustable Reference Voltage. You can
use this feature with either output range
-2.5V to +2.5V or
to +2.5V. If for example you adjust potentiometer R4 to
2.3 V (instead of the default setting of 2.5), then an input signal
of 1.2 results in an output voltage of (1.2 / 2.5) * 2.3 V = 1.1 V.
See the board manual for details.
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
the corresponding channel is reset to the value specified in the initial
value vector. If you specify a value of
channel remains at the last value attained while the model was running.
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 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 a value that is out of the channel's range, the value is reset to the lower or upper range value.
Enter the base sample time or a multiple of the base sample
-1 means sample time is inherited).
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
