IO207 - Setup
IO207 - Setup — Configure the IO207 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
Tab: 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")
-
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.
Tab: Front Channels Setup
-
Enabled Channels
This field enables either the first half of the channels (the rest of
the channels will be disabled) or all the channels. The value IO1 ... IO32 only enables the
channels 1 to 32, and the value IO1 ... IO64 enables all the channels 1 to 64.
-
Simultaneous Update
Available only when all the channels are enabled (see Enabled Channels). When set to OFF, the first group of channels, 1 to 32,
and the second group of channels, 33 to 64, are updated sequentially.
When set to ON, all 64 channels are
updated simultaneously. Enabling this option leads to greater latencies.
-
Directions
This field specifies whether the enabled channels act as inputs or
outputs. Enter a scalar or a vector with a width of either four or eight
(depending on the Enabled Channels
field). When a scalar value is specified, its value is used for all
enabled channels. When a vector is specified, one value of this vector
represents a group of eight channels (in sequential order, see the
Pin Mapping). A value of
0 defines the group of channels as
input, and a value of 1 defines the
group of channels as output. Examples with all channels enabled: a
scalar of 1 will set all channels as output, and a vector of
[1 1 1 1 0 0 0 0] will set the first
four groups as output (channels 1 to 32) and set the next 4 groups as
input (channels 33 to 64).
-
Pull Resistors
This field configures the pull-up/-down resistors of the enabled
channels. Enter a scalar or a vector with a width of either four or
eight (depending on the Enabled Channels field). When a scalar value is
specified, its value is used for all enabled channels. When a vector is
specified, one value of this vector represents a group of eight channels
(in sequential order, see the Pin Mapping). A value of 0 specifies a pull-down resistor, and a value of
1 specifies a pull-up resistor of
5 V, 2 specifies a pull-up
resistor of 3.3 V and 3 specifies
a floating line. Examples with all channels enabled: a scalar of 1 will
set a pull-up resistor of 5 V to all channels, and a vector of
[0 0 3 3 2 2 2 2] will set channels 1
to 16 with pull-down resistors, channels 17 to 32 with floating lines
and channels 33 to 64 with pull-up resistors of 3.3 V.
-
Initial Values
This field specifies the initial value of the channels after the model
has downloaded. Enter a scalar or a vector with a width of either 32 or
64 (depending on the Enabled Channels field). When a scalar value is
specified, its value is used for all enabled channels. When a vector is
specified, one value of this vector represents one channel (in
sequential order, see the Pin Mapping). A value of 0 causes the corresponding channel to output a low
level, and a value of 1 causes the
corresponding channel to output a high level.
-
Reset to Initial Values
This field specifies the behavior of the channels at model
termination. Enter a scalar or a vector with a width of either 32 or 64
(depending on the Enabled Channels
field). When a scalar value is specified, its value is used for all
enabled channels. When a vector is specified, one value of this vector
represents one channel (in sequential order, see the Pin Mapping). A value of 0 causes the channel to remain at the last
used value when the model was running, and a value of 1 causes the corresponding channel to be
reset to the value specified in the Initial Values field.
Tab: Rear Channels Setup
-
Enabled Channels
This field enables either the first half of the channels (the rest of
the channels will be disabled) or all the channels. The value IO65 ... IO96 only enables channels
65 to 96 and the value IO65 ... IO128 enables all the channels 65 to
128.
-
Simultaneous Update
Available only when all the channels are enabled (see Enabled Channels). When set to OFF, the first group of channels, 65 to 96,
and the second group of channels, 97 to 128, are updated sequentially.
When set to ON, all 64 channels are
updated simultaneously. Enabling this option leads to greater latencies.

resistor of 5 V to all channels, and a vector of
[0 0 3 3 2 2 2 2] will set channels
65 to 80 with pull-down resistors, channels 81 to 96 with floating
lines, and channels 97 to 128 with pull-up resistors of 3.3 V.
