Select the name of the configurable I/O module for which you are defining the setup parameters.

The Module ID identifies the configurable I/O module in the target machine and creates a logical connection to all the code module blocks associated with this I/O module. The Module ID of all the code module blocks intended for use with a specific I/O module in your machine must match the Module ID in the IO3xx Setup block.

Unlike other module types, the Module ID parameter must be unique for each Simulink-programmable and configurable I/O module. To obtain the Module ID for use with your I/O modules, run the following Speedgoat API in the MATLAB command window:

>> speedgoat.getIoInterfaces

	Important
	If your target machine contains more than one configurable or Simulink-programmable I/O module of the same type (e.g. 2x IO334-325k), but the model does not contain IO3xx Setup blocks for all of these modules, use explicit addressing for the PCI Slot parameter to clarify the module you want to use.

Example Setup for a Target Machine with the I/O Modules Listed Above:

To run a model with PWM Generation on the IO336-325k in slot 2 and PWM Capture on the IO334-325k in slot 3, configure two IO3xx Setup blocks: one with ModuleID=3 for the IO336, and one with ModuleID=4 for the IO334. As there are two IO334 I/O modules in the machine, use explicit addressing for the PCI Slot parameter. Finally, set the ModuleIDs of the PWM blocks: configure the PWM Generation block with ModuleID=3 and the PWM Capture block with ModuleID=4.

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.

This parameter defines the configuration file (bitstream) to download to the FPGA of your configurable I/O module when your Simulink model is built and the application deployed to the target machine. The configuration file defines the pin mapping and the implemented functionality (code modules). The dropdown will show installed configuration files, files located in the actual working directory and files from installed Speedgoat I/O Configuration Packages. A configuration file can also be selected from a different location by using the Browse button. The entries are automatically limited to configuration files matching the selected I/O module.

This button opens a file explorer window to select a configuration file (.mat-file) from any location. The selected file is automatically applied as the new configuration file if compatible with the selected I/O module.

	Note
	Moving or renaming the file will remove the file from the dropdown, since the Setup block cannot find the file anymore.

This collapsible panel shows additional information about the selected configuration file.

Selecting a checkbox will enable the corresponding I/O interface extension. When not selected, the functionality located on the extension is disabled. The number and the type of selectable extensions depends on the configuration file.

Selecting the [IOMODULE] controlled checkbox changes the data transfer behavior between the hardware and the model, as well as the model trigger behavior. When this checkbox is selected, the model must be triggered and executed in polling mode using the Interrupt Setup block. The Add Interrupt Setup Block button automatically inserts a preconfigured block into the model (if the block is not already in the model). For normal model execution, deselect [IOMODULE] controlled and remove the Interrupt Setup block from the model.

When [IOMODULE] controlled is selected and the corresponding Interrupt Setup block is available in the model, all the driver blocks with the fastest model rate combine their data transfers to and from the CPU into single DMA transfers. This feature is particularly helpful to synchronize data sampling and reduce task execution time for highly demanding closed-loop applications. For detailed information about which functionality of the selected configuration file supports optimized data transfer or DMA, open the pin mapping window using the Pin Mapping button and check the Details tab.

	Note
	The Interrupt Setup block must be configured as follows if Optimize Data Transfer is used: The correct Interrupt Source must be selected (Speedgoat IO3xx FPGA polling) The Use as Model Trigger parameter must be selected The Use in Polling Mode parameter must be selected

When running a model using Optimize Data Transfer, the model triggering is controlled outside of the CPU of the target machine. If the configuration of the model sample rate is too demanding for the given setup and application, and results in a sample rate overload, select the Stop Model on Overload checkbox to control the stop behavior:

	Note
	Allowing task overloads by deselecting Stop Model on Overload should only be used in order to optimize the model step calculation time. Adding the DMA Controller v1 driver block to the model allows you to measure the exact timing duration and see overload indications for each model step.

This parameter is only visible if the selected configurable I/O module and configuration file supports different trigger sources for the optimized data transfer. If the parameter is not visible, the Model Step option is used.
