MM-32-AT Digital Input block
Simulink® Real-Time™ Library for Diamond
The Diamond-MM-32-AT has one 8255 chip with three 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 input driver block, you configure the port as input.
I/O Module Input
Block Output Data Type
TTL low = 0.0
Enter numbers between 1 and 8 to select the digital input lines used with this port. This driver allows the selection of individual digital input lines in arbitrary order. The number of elements defines the number of digital lines used.
For example, to use all the digital inputs 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
C. The I/O board has an 8255 chip with three
ports. The Port parameter defines which port
of the 8255 chip is used for this driver block. Each port has a maximum
of eight digital lines that you can configure as inputs or outputs
depending on which driver block is chosen. One block is required for
each port used.
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
