Channel Vector - 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 any order. The number of elements defines the number of digital
lines used.
For example, to use all of the digital inputs for one port, enter
[1,2,3,4,5,6,7,8]
Number the lines beginning with 1 even if the board manufacturer starts
numbering the lines with 0.
Port - From the list choose either A, B, or C. The I/O board has two 8255 chips
with 3 ports. The Port parameter 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 needed for each port.
Chip - From the list choose 1 or 2. The Chip parameter defines which of the
two 8255 chips is used.
Sampletime - Enter a base sample time or a multiple of the base sample time.
BaseAddress - Enter the base address of the board. This entry must
corresponds to the DIP-switch settings on the board. For example, if the base
address is 300 (hexadecimal), enter
0x300
