IO901/IO902 - Setup

IO901/IO902 - Setup — Configure the IO901/IO902 I/O modules

Library

Simulink Real-Time - Speedgoat

Description

Configures the SCRAMNet GT shared memory board. It configures important registers on the board acording to the user-defined node structure.

For each IO901/IO902 I/O module in your target machine there should be exactly one Setup block in your model.

Before you begin to configure this block, ensure that you have a predefined node initialization structure. Refer to the Usage Notes.

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")
Node Struct

Enter the name of the predefined node initialization structure.

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.
