IO623 - Setup
IO623 - Setup —
Configure the IO623 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).
Ports
This driver block has no input or output ports.
Parameters
-
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.
-
IO623 Variant
The IO623 I/O module is available in three variants which differ in
terms of the number of available bus interfaces. Select the variant that
has been installed in your target machine.
-
CHI File
The CHI file contains the configuration for a specific communication
controller (CC). There is one CC for each installed bus interface
available. The number of installed bus interfaces depends on the IO623
variant in your target machine.
You can download a tool from the Speedgoat Customer Portal which
imports a FIBEX file with your bus configuration and exports the
necessary CHI files for the I/O module.
Click on the Browse button to select
the CHI file.
-
Enable
This setting enables the corresponding CC.
You cannot use the CC in the Send and Receive blocks until it has been
enabled in the Setup block.
CC1 does not have this checkbox because it must always be enabled and
connected to the FlexRay bus to generate the interrupts which trigger
the IO623 driver blocks (see Usage Notes).
-
Bus Termination
Adds a bus termination resistor of 90 Ohm to both channels A and
B.
