PMC-16AO-12 Analog Output block
Simulink® Real-Time™ Library for General Standards
The analog output range of this board depends on the output
range that was chosen at the time of purchase. This range can be
I/O Module Output
Block Input Data Type
Enter numbers between 1 and 12. This is a vector parameter that specifies the output channels. For example, to produce output on channels 2 and 3, enter
The unspecified channels are set to 0.0 volts on output.
Number the channels beginning with 1 although the board manufacturer starts numbering the channels with 0.
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
[ 2 3 ] and
the Reset vector is
action taken will be the same as if Reset vector was
[1 1]. Both channels will be reset to their
initial values when model execution is stopped.
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. 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
5 8], Reset vector is
1], and Initial value vector is
5.6 0]. On initial download, channel 2 is set to 2.3 volts,
channel 5 to 5.6 volts, and channel 8 to 0.0 volts. When the model
is stopped, channel 2 resets to 2.3 volts, channel 5 remains at the
last value attained, and channel 8 resets to 0.0 volts.
From the list, choose either
+-10.0. The PMC-16AO-12 is specified at purchase
time as having one of these three ranges. Choose the range to match
that for which the board is configured.
Note that the range you set does not alter the configuration on the board. It is used to scale the signal when it is converted to a 16-bit value to be written to the output D/A converter (DAC).
The PMC-16AO-12 can check its own calibration (autocalibration) against an internal voltage reference. Choose this check box to execute the autocalibration cycle when the model is downloaded to the target computer. The output ports show a square wave during the cycle. The calibration cycle yields adjustment factors that are retained in onboard NVRAM. The PMC-16AO-12 reads these adjustment factors when the board is initialized. Unless you subject this board to harsh conditions, you should only need to run autocalibration occasionally—for example, once a month.
Note: The calibration cycle takes several seconds to run. Refer to the manufacturer documentation for further information on autocalibration.
Choose this check box to enable onboard compensation for ground potential differences. Refer to the manufacturer documentation for further information on ground sense.
