IO113 - Setup
IO113 - Setup — Configure the IO113 input/output
blocks
Library
Simulink Real-Time - Speedgoat
Description
Your model can contain only one Setup block
for each I/O module in your target machine.
The Setup block dialog box allows all the supported I/O types of this module to be
configured and therefore impacts on the other driver blocks (Analog output, Digital
output, Digital input).
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:
Module setup
Analog output setup
Digital I/O setup
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")
-
Autocalibration
Check this box if the module should calibrate itself the next time
this model (target application) is downloaded and initialized. The
autocalibration function compensates for component aging and minimizes
the effects of temperature on accuracy. We recommend keeping this
enabled. The calibration normally takes approximately 2 seconds, so we
suggest increasing the host-target communication time-out in the model
configuration parameters to allow for this. The status of the
calibration is displayed on the target screen. The calibration is not
re-executed during normal start/stop operation once the target
application has been downloaded. Warning: During the calibration process
various signals may be present at the output pins, but they will stay
inside the configured voltage range.
-
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: Analog output setup
-
Output Range
Select one of the three available analog output ranges. The selected
range applies to all analog channels.
-
Mode
Select either Single-ended or Differential. For more information
please see the I/O pin mapping section and the technical reference
manual of the I/O module. For Single-ended channels each output signal
is referenced between the HI line and the Output return (GND). For
Differential channels the voltage is referenced between the HI line and
LO line.
-
Active Channels
Select the active input/output channels in a vector. A defined number of channels
can be selected using square brackets, for example [1 2 3]. A sequence of channels
can be selected using a colon, for example, 1:4.
-
Initial Values
Define the initial signal level present on the outputs after the application has
been downloaded. The values can be set individually by entering a vector: the value
at a certain position in the Initial Values vector is applied to the channel as
defined in the Active Channels vector. A scalar value applies to all the channels;
for example, for individual values, type "[1 1.5 0 2.5]", and to set all channels to
zero, type "0".
-
Reset to Initial Values
Define whether the initial values are also applied once the application has
stopped. The behavior can be set individually for each channel using a vector. A
scalar value applies to all the channels; for example, for individual values, type
"[1 0 0 1]", and to set all channels to zero, type "0". "1" means use the Initial
Value and "0" means keep the latest value.
Parameter group: Digital I/O setup
- Direction of Channels 1-4
The direction (Input or Output) for channels 1 to 4
-
Direction of Channels 5-8
The direction (Input or Output) for channels 5 to 8
-
Initial Values
Define the initial signal level present on the outputs after the application has
been downloaded. The values can be set individually by entering a vector: the value
at a certain position in the Initial Values vector
is applied to the channel as defined in the enabled channels. A scalar value applies
to all the channels; for example, for individual values, type "[1 0 0 1]", and to
set all channels to zero, type "0".
-
Reset to Initial Values
Define whether the initial values are also applied once the application has
stopped. The behavior can be set individually for each channel using a vector. A
scalar value applies to all the channels; for example, for individual values, type
"[1 0 0 1]", and to set all channels to zero, type "0". "1" means use the Initial
Value and "0" means keep the latest value.
