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.

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")

There are a total of 24 digital I/O channels. These are organized into three banks (A, B and C) and can be configured as inputs or outputs in groups of eight, with the exception of bank C (I/O channels 17-24) which can be split into two groups of four I/O lines. All the channels are configured as inputs at power-up or after module reset.

Active Output Channels

Select the active 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 enabled channels. 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".

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.

Active Input Channels

Select the active input channels in a vector. Check the active output channels to avoid conflicts.
