IO203 - Setup
IO203 - Setup — Configure the IO203 read/write
block
Library
Simulink Real-Time - Speedgoat
Description
Your model can contain only one Setup block
for each I/O module in your target machine.
Ports
This driver block has no input or output ports.
Parameters
-
Parameter group
This control selects an I/O section, the parameters of which are then
shown in the dialog box below the 'Parameter group' field. Possible
groups are:
Parameter group: Module setup
-
Module ID
The Module ID has two functions:
It defines the logical connection between the Setup block and its I/O
blocks
It also informs the auto-search feature of the PCI Slot parameter. If
only one I/O module of this type is installed, the Module ID must be set
to 1. If n modules are installed, it
must be in the range 1:n. Not all the I/O modules installed in the
target machine need to be used. To see how each I/O module maps to a
Module ID, use this Speedgoat API:
speedgoat.getIoInterfaces("TargetName", "mySpeedgoat")
-
Enable 5V TTL output level
Enable 5V output level instead of 3.3V. In addition, the jumper J1 on
the I/O module must be set correctly.
-
PCI Slot (-1: auto-search)
There are two approaches for mapping this block to a specific I/O module installed
in your target machine. All modules of the same type must be configured using the
same method.
Auto-Search: with the default value -1 the I/O module will be automatically located in the
target machine. If you have multiple modules of the same kind, the
Module ID defines which module is associated with this block. To see how
each I/O module maps to a Module ID, use this Speedgoat API:
speedgoat.getIoInterfaces("TargetName", "mySpeedgoat")
Explicit Addressing: to explicitly define the logical address of the
I/O module in the target machine, you can provide the PCI bus and slot
numbers as a vector: [bus, slot]. To determine these numbers, run the
following command in the MATLAB command window:
speedgoat.getIoInterfaces("TargetName", "mySpeedgoat", "Advanced", true)Note
that the PCI address can change whenever an I/O module is added or
removed – usually, auto-search is the best option.
Parameter group: Lower channel group setup
-
Direction vector
Enter a scalar or a vector with a width of 32 to configure whether the
channels acts as inputs or outputs. A value of 0 defines a channel as
input, 1 defines a channel as output. If a scalar value is specified,
its value will be used for all channels. Examples: [1 1 1 1 1 1 1 1 1 1
1 1 1 1 1 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0] = 16 outputs and 16 inputs
1 = 32 outputs
-
Reset vector
This field specifies the behaviour of the channels at model
termination. Enter a scalar or a vector of the same length as the
channel vector. If a scalar value is specified, its value will be used
for all channels. A value of 1 causes the corresponding channel to be
reset to the value specified in the 'Initial value vector' field. A
value of 0 causes the channel to remain at the last value used while the
model was running.
-
Initial value vector
This field specifies the initial value of the channel after the model
is downloaded. Enter a scalar or a vector of the same length as the
channel vector. If a scalar value is specified, its value will be used
for all channels. A value of 1 causes the corresponding channel to
output a high-level, 0 a low-level.
Parameter group: Upper channel group setup
-
Direction vector
Enter a scalar or a vector with a width of 32 to configure whether the
channels acts as inputs or outputs. A value of 0 defines a channel as
input, 1 defines a channel as output. If a scalar value is specified,
its value will be used for all channels. Examples: [1 1 1 1 1 1 1 1 1 1
1 1 1 1 1 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0] = 16 outputs and 16 inputs
1 = 32 outputs

Initial value vector

channel vector. If a scalar value is specified, its value will be used
for all channels. A value of 1 causes the corresponding channel to
output a high-level, 0 a low-level.
