qc_open_library('quarc_library/Data Acquisition/Generic/Immediate I//O')Description
The HIL Read Analog block reads the specified analog channels every time the block is executed. The channels are read immediately.
Input Ports
This block has no input ports.
Output Ports
The number of output ports depends on the Vector output parameter. If this option is checked then the output is a vector containing the analog voltages (or current for current sensing devices) read from the channels specified in the Channels parameter. Otherwise there is one output port for each channel and each port outputs the analog voltage read from the corresponding channel. Refer to the documentation on the Vector output parameter below for more details.
Data Type Support
The HIL Read Analog block outputs real signals of type double.
Parameters and Dialog Box
Board Name
The name of the board whose analog channels will be read. Boards are configured using the HIL Initialize block. Place an HIL Initialize block in your diagram to add a board name to the list.
Channels
The analog channels to read. The number of channels available depends on the board selected. Refer to Channels for more information.
Select a board type from the list for board-specific details:
Sample time
The sample time of the block. A sample time of 0 indicates that the block will be treated as a continuous time block. A positive sample time indicates that the block is a discrete time block with the given sample time.
A sample time of -1 indicates that the block inherits its sample time. Since this is a source block, only inherent the sample time when it is placed in a conditionally executed subsystem, like a Triggered or Enabled Subsystem, or in a referenced model.
The default sample time is set to qc_get_step_size, which is a QUARC function that returns the fundamental sampling time of the model. Hence, the default sample time is a discrete sample time with the same sampling time as the fixed step size of the model.
Vector output
If this option is checked then the block will have a single vector output with one element in the vector for each channel. The voltages read from each channel will appear in the vector in the same order as the channels in the Channels parameter.
If this option is not checked then the block will have one output for each channel. The output ports will appear in the same order as the channels in the Channels parameter. Each port will be labeled with the corresponding channel number.
