CIO DAS1602/16 Digital Output block (not recommended)
Simulink® Real-Time™ Library of Drivers No Longer Recommended for Use
The DAS1602/16 has an 8255 chip with 3 ports (A,B,C). Each port has a maximum of 8 digital I/O lines that can be configured as inputs or outputs.
Use a separate driver block for each port. By selecting the digital output driver block, the port is configured as output.
I/O Module Output
Block Input Data Type
< 0.5 = TTL low
Enter numbers between 1 and 8 to select the digital output lines used with this port. 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 for one port, enter
Number the lines beginning with 1 even if this board manufacturer starts numbering the lines with 0.
From the list choose either A, B, or C. The I/O board has an 8255 chip with 3 ports. The port name defines which port of the 8255 chip is used for this driver block. Each port has a maximum or 8 digital lines that can be configured as inputs or outputs depending on which driver block is chosen. In each case, one block is required for each port.
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 values (
of the output channels. Enter a scalar or a vector that is the same
length as the channel vector. If you enter a scalar, that value is
replicated as the initial value over the channel vector. The channels
are set to these initial values between the time the model is downloaded
and the time it is started.
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
