IO203 - Setup v2

IO203 - Setup v2 — Configure the IO203 read/write v2 block

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

Module setup 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.

Enable 5V TTL output level

Enable 5V output level instead of 3.3V. In addition, the jumper J1 on the I/O module must be set correctly.

Channels Setup Tab
Use Checkboxes for I/O Direction

Select this option to use the matrix of checkboxes "Checkboxes channels configuration" to define the direction of the digital channels, or clear it to define it with the "Direction Vector".

Direction vector

Warning: To use this field, also in remote with set_param(), be sure that "Use Checkboxes for I/O Direction" is off.

When the "Use Checkboxes for I/O Direction" is not selected (cleared), the direction of the digital channels is configured with a vector of 64 elements of the type doubles, where the index number corresponds to the channel number. The value "0" defines the channel as Input, and the value "1" defines the channel as Output.

When the "Use Checkboxes for I/O Direction" is selected, this field is updated with the configuration used in the "Checkboxes channels configuration", and it can not be modified.

Checkboxes channels configuration

When the "Use Checkboxes for I/O Direction" is not selected (cleared), this matrix of checkboxes is used to represent the "Direction vector", and it can not be modified.

When the "Use Checkboxes for I/O Direction" is selected, this field is used to define the direction of each channel. As indicated in the Legend, when the channel's checkbox is cleared the channel is set to Input, and when the channel's checkbox is selected the channel is set to Output. The new configuration is then also represented in the deactivated field "Direction Vector". The "Toggle all" button takes the state of the first checkbox, and assign to all the channels the opposite state.

Reset vector

This field specifies the behaviour of the channels at model termination. Enter a scalar or a vector of the same length as the channel vector. If a scalar value is specified, its value will be used for all channels. A value of 1 causes the corresponding channel to be reset to the value specified in the 'Initial value vector' field. A value of 0 causes the channel to remain at the last value used while the model was running.

Initial value vector

This field specifies the initial value of the channel after the model is downloaded. Enter a scalar or a vector of the same length as the channel vector. If a scalar value is specified, its value will be used for all channels. A value of 1 causes the corresponding channel to output a high-level, 0 a low-level.
