PMC-ADADIO Digital Output block
Simulink® Real-Time™ Library for General Standards
Note that you cannot use the PMC-ADADIO Digital Input and Digital Output driver blocks simultaneously on the same board. Doing so causes an error at model update or build.
I/O Module Output
Block Input Data Type
< 0.5 = TTL low
The values passed to the enable input port and enable output port of this block are Boolean values.
Enter numbers between 1 and 8 to select the digital output lines to be written. This driver allows the selection of individual digital output lines in arbitrary order. The number of elements defines the number of digital lines used.
For example, to use all of the digital outputs, enter
Number the lines beginning with 1 even if this board manufacturer starts numbering the lines with 0. Note that the 8 digital lines are either all input or all output.
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 logical values
for the output channels. Enter a scalar or a vector that is the same
length as the channel vector. These values can only contain 1's and
0's. 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
[2 5 8], Reset
[1 0 1], and Initial
value vector is
[1 1 0]. On initial
download, channel 2 is set to high, channel 5 to high, and channel
8 to low. When the model is stopped, channel 2 resets to high, channel
5 remains at the last value attained, and channel 8 resets to low.
Select this check box to display an input enable port that controls writing data to the digital output ports on the I/O module. If the enable input signal is true, then the block input data is written to the digital output ports. If the enable input signal is false, then data is not written to the digital output ports and the output remains at the previous value. If this check box is not selected, then the enable input signal is assumed to be true.
Select this check box to pass the Boolean value from the input enable port to the output enable port. You can connect this port to the input enable port on another block to control other blocks in the model and specify execution ordering.
