IO624 - Setup
IO624 - Setup —
Configure the IO624 I/O module
Library
Simulink Real-Time - Speedgoat
Description
Your model can contain only one Setup block
for each I/O module in your target machine.
All the supported I/O types for this module can be configured in the Setup block
dialog box. This block will therefore have an impact on other driver blocks (Send,
Receive, Sync Status, Sync Pulses and Wheel Speed (WS) Control).
Ports
This driver block has no input or output ports.
Parameters
The nine tabs of the Setup block contain the IO624 I/O module configuration
settings.
Refer to the IO624
main page for the cycle time and bit time specifications, as well as
details about the max time factor mentioned below.
Main Tab
-
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.
-
Channel X
The IO624 I/O module supports up to eight channels. Each channel can
be disabled or selected as a PSI5, custom, square wave, PWM, or AK/VDA
sensor emulator.
-
Channel Monitor
The module measures the voltage between the VDD and VSS pins. The main
application is for Sync pulse. The channel selected is in the Receive
block.
Channel Tab

parameter based on the communication protocol selected. Custom enables the configuration parameters.
High, Mid and/or Low
parameters are available depending on the sensor emulator
selected.
-
High [μA]
Defines the high current level in microamperes (0 to 75000).
-
Mid [μA]
Defines the mid current level in microamperes (0 to 75000).
-
Low [μA]
Defines the low current level in microamperes (0 to 75000).
-
Time Base Setting
The time base must be multiplied by the time factor to obtain the
cycle time or the bit time in the configuration. If there is no
indication that the time base is fixed, then these are the
options:

Emulator is selected in the Main tab. All the input and output

blocks.

-
Default Payload
Defines the default data frame transferred from the sensor to the
ECU. The payload must include the parity or CRC bits. The bits are
transmitted in ascending order, starting with bit 0. The Default Payload is only sent when the
Sensor Send block has no input data. In PSI5-D (Synchronous Daisy
Chain) mode, the default payload is transmitted until the sensor
address is received from the ECU. The default payload length is
32-bit words. Data Type: uint32.
