Analog IO33x-06 - Input v1
Analog IO33x-06 - Input v1 — This driver block is
available for the IO33x-06 module only.
Library
Simulink Real-Time - Speedgoat
Description
This driver block is available for the IO33x-6 module only.
Your model can only contain one of these blocks for each I/O module in your target
machine.
Ports
This block has as many outputs as defined by the channel vector.
Outputs
-
X (X is channel number)
The value read from analog input X. Type double.
Parameters
-
Configurable I/O Module ID
This parameter associates a code module block with a configurable I/O module setup
block. Set this value to match the Module ID defined in the setup block of the
required configurable I/O module.
-
Channel Vector
A vector of channels this driver block entity will access. You can specify
channels in the range 1-N (N = the number of channels implemented in your specific
configuration file defined in the Setup block). The width of this vector also
defines the subsequent size of some of the following parameters if scalar expansion
applies. With a single block, all the channels of the block are synchronized.
-
Analog input range
For better accuracy, small voltages can be amplified - this parameter
is used to indicate the expected input voltage range:
± 10 [V]
± 5 [V]
± 2.5[V]
± 1.25 [V]
-
Inter-module synchronization
This parameter defines if the model initiates the sampling. In this
case the driver is an initiator. The "ADC trigger" physical pin becomes
an output which propagates this signal. If the sampling is triggered by
an external source, the driver is then configured as target. In this
case the "ADC trigger" physical pin becomes an input used to read a
trigger signal.
-
Sample Time
Defines the base sample time at which this driver block gets its sample hit. This
parameter can also be set to -1 for inherited
sample time. The units are in seconds.
