Description
This section describes the driver block used with the IO421-5 sub-module.
The characteristics of the sub-module depend on the factory configuration selected
at the time of the order. This information is available in a separate documentation
shipped with the device.
Output power: max. 6VA
Ports
This block has no input or output ports.
Parameters
-
Module ID
A unique module ID must be used for each type of IO421 module 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
-
Slot
The carrier board can contain up to three modules. This parameter
indicates where your IO421-5 sub-module is located.
-
Reference Frequency
The output frequency (excitation frequency) Units: Hz
-
Reference Voltage
The output voltage (excitation voltage) Units: Vrms
-
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.
