IO107 - Setup

IO107 - Setup — Configure the IO107 input/output blocks

Library

Simulink Real-Time - Speedgoat

Description

All the supported I/O types for this module can be configured in the Setup block dialog box. Please note that this block will have an impact on the Analog output driver block but not on the Analog output (DMA) block.

Ports

This driver block has no input or output ports.

Parameters

Parameter group

This control selects an I/O section, the parameters of which are then shown in the dialog box below the 'Parameter group' field. Possible groups are:

  • Module setup

  • Analog output setup

Parameter Group: Module Setup
Module ID (IO107+IO108)

A unique module ID must be used for each type of I/O module Setup block in your model.

The module ID has two functions:

  • It defines the logical connection to link the I/O module driver blocks with each other

  • It also has an impact on the PCI slot auto-search feature: if only one I/O module is installed, the module ID must be set to 1. If multiple 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

The IO107 I/O module uses the same module identifiers as the IO108 I/O module. If your target machine contains both of these modules, assign different values to each of them.

Analog Range

The voltage range for the analog output channels. The same range applies to all channels. For the IO107-HV version of the module, the ranges for "high-voltage ordering option" must be used.

External Sync Signal Type

Select a signal type for the clock output signal that can be connected to other input boards or to the IO107 output board.

Enable Remote Ground Sense Correction

Select this check box to enable the remote ground sense correction. See the IO107 reference manual for more information about this function.

Autocalibrate

Check this box if the module should calibrate itself the next time this model (target application) is downloaded and initialized. The autocalibration function compensates for component aging, and minimizes the effects of temperature on accuracy. We recommend keeping this enabled. The calibration normally takes approximately 2 seconds, so we recommend increasing the host-target communication time-out in the model configuration parameters to allow for this. The status of the calibration is displayed on the target screen. The calibration is not re-executed during normal start/stop operation once the target application has been downloaded.

Warning: During the calibration process various signals may be present at the output pins, but they will stay inside the configured voltage range.

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.

Parameter Group: Analog Output Setup
Active Channels

Select the active input/output channels in a vector. A defined number of channels can be selected using square brackets, for example [1 2 3]. A sequence of channels can be selected using a colon, for example, 1:4.

Initial Values

Define the initial signal level present on the outputs after the application has been downloaded. The values can be set individually by entering a vector: the value at a certain position in the Initial Values vector is applied to the channel as defined in the Active Channels vector. A scalar value applies to all the channels; for example, for individual values, type "[1 1.5 0 2.5]", and to set all channels to zero, type "0".

Reset to Initial Values

Define whether the initial values are also applied once the application has stopped. The behavior can be set individually for each channel using a vector. A scalar value applies to all the channels; for example, for individual values, type "[1 0 0 1]", and to set all channels to zero, type "0". "1" means use the Initial Value and "0" means keep the latest value.
