IO751 - Setup

IO751 - Setup — Configure the IO751 IO module

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: Configuration
Module ID

The Module ID has two functions:

  • It logically connects 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 family is installed, the Module ID must be set to 1. To see how each I/O module maps to a Module ID, use this Speedgoat API: 

    speedgoat.getIoInterfaces("TargetName", "mySpeedgoat")

This Setup block belongs to two families of I/O modules that use the same hardware for multiple protocols. Across both families, the Module ID must be unique.

  • IO64X/IO75X (single-node modules): IO641, IO642, IO643, IO644, IO750, IO751, IO752, IO753, IO754, IO755, IO756, IO758

  • IO64X-32/IO75X-32 (multi-node modules): IO642-32, IO752-32, IO754-32, IO756-32

If the PCI Slot parameter is set to -1 (auto-search), the Module ID must be in the range 1:n, where 'n' cannot be larger than the number of modules of this type installed in the target machine. Not all installed I/O modules need to be used.

To use this Setup block with a multi-node I/O module (IO75X-32 family), the Module ID must be defined as a two-element vector. The second vector element is the sub-module ID. It describes the specific node (1:32) within the I/O module. The 32 nodes are internally connected to form two linear networks (daisy-chain), where the first and the last node of both chains are externally accessible. If one node is not configured (has no Setup block), the chain terminates at this point. The sub-module IDs must therefore start at node 1, 16, 17 or 32 and not have any gaps.

[Note]Note

When using I/O modules of both families simultaneously (single-node and multi-node I/O modules), always use explicit addressing in the PCI Slot parameter. Ignore the Module IDs returned by the getIoInterfaces function and instead assign unique Module IDs accross all modules used.

Target Machine Drive Letter

The drive letter of your target machine where the firmware and configuration files will be stored. The default drive is "C:\".

[Note]Note

This parameter serves no purpose in MATLAB R2020b and later.

Configuration Mode

This setting is not yet available.

Sample Time

Defines the base sample time at which this driver block gets its sample hit. This parameter can also be set to -1 for inherited sample time. The units are in seconds.

[Caution]Caution

All blocks that interface with the same I/O module must have identical sample times.

PCI Slot (-1: auto-search)

There are two approaches for mapping the block to a specific I/O module installed in your target machine. All modules of the same family (see Module ID above) 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 family, 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.
